Unlocking for Industrial Users the Power of ROS 2: ROS-I October Training Highlights

The ROS-Industrial Consortium Americas provided a hybrid, online/in-person, ROS 2 training October 22-24. The three-day ROS-I developers training class was given to trainees from across the ROS-Industrial Consortium membership.

Whether you are just starting to use, are already experienced in ROS 2, the training offered something for all levels. Newcomers learned the ropes, getting a solid foundation in the framework’s core concepts, while experienced developers delved into advanced topics such as advanced motion planning, including tuning optimizatoin contsraint parameters.

Currently training is on ROS 2 Humble, delivered through an AWS EC2 instance. On the first day, the attendees were divided into two groups: beginner ROS developers and advanced ROS developers. The advanced group learned how to set up a basic motion planning pipeline in Tesseract, where they refined a planning pipeline increasing robustness. By the end of the day students were adding unique customizations to the pipeline.

The beginner group focused on learning the fundamentals of ROS 2, including workspace structure and best practices for adding scripts and building the workspace. They also learned about creating packages / nodes, topics (publishers / subscribers), messages, services, actions, launch files and command line parameters.

Day 2, groups gathered to learn how to develop URDF/XACROs to describe a robot, as well as how to use TFs and create a MoveIt Package for an industrial robot for motion planning in a simulation environment.

Day 3 started with a tour that focused on ROS 2 robotic systems within the Robotics Department at SwRI, where the instructors were able to give insights on the capabilities of ROS 2 in more tangible working industrial examples.

Wrapping up the training participants were given the opportunity to share with instructors and the group how they intended to use ROS in their projects and where already under way the instructors were able to provide additional assistance to address issues in their application development back home.

Hybrid training always presents challenges, in making sure those online get the same attention as those in the room. However, it was rewarding to assist attendees in getting deeper into ROS 2, whether they were just starting out or wanting to expand their solution set or add features to an ongoing project. As always, as instructors, we always look forward to seeing how they apply these new skills and always look forward to interactin through the repositories or various ROS/ROS-I collaborative events.

Scan-N-Plan with the ORBBEC Femto-Mega

During the annual ROS-I Consortium Americas meeting in March, ORBBEC provided for evaluation to Southwest Research Institute (SwRI) a Femto Mega, a depth+RGBD camera. Since then, the ROS-I team has tested the performance of the Femto Mega within the standing Scan-N-Plan demo and qualitatively compared it to the previously used camera, an Intel RealSense D455.   

SwRI’s Scan-N-Plan demo utilizes RGB-D depth sensor to generate colored point clouds. The point clouds are utilized by Industrial Reconstruction to generate a colored mesh of the object in the environment. In the Scan-N-Plan demo, the scanned object is the underside of a white paint wok.

Scan-N-Plan demo with ORBBEC Femto Mega mounted on a Yaskawa HC10

Setup 

Setting up the Femto Mega was relatively easy. There is github page for ORBBEC ROS2 drivers and documentation on how to install and use the driver, as well as download the OrbbecViewer. The datasheet was helpful for determining valid combinations of frame rate and resolution that the Femto Mega could be configured with the driver. The Femto Mega’s power over ethernet feature made long cable runs convenient and the publishing rate for the sensor data was very stable thanks to the onboard computing. 

Qualitative Comparison 

After calibrating each camera, we ran a scan using the D455 and then the Femto Mega. The Femto Mega had much less noise in the depth data and produced crisper edges. The Femto Mega also handled glare much better than the D455. In the reconstructed mesh, the Femto Mega had better surface quality than the D455. However, the D455 did result in a reconstructed mesh that had less blurring of the color data, particularly when looking at the written blue text. This is likely an artifact of how Industrial Reconstruction averages color data when reconstructing the mesh and may be further optimized in configuration settings.

ROS-I Americas Puts On Training at Wichita State hosted by Spirit AeroSystems

This July, the consortium conducted a training at Wichita State University (WSU), more specifically National Institute for Aviation Research (NIAR), hosted by Spirit Aero Systems, from July 16th-18th. The attendees contained consortium members from Spirit Aero System, NIAR, Iowa State University, and Santa Clara University. This training was a great first exposure for those who haven’t touched ROS 2 before, while those more seasoned in ROS development got to dip their toes in motion planning with Tesseract. There were many moments where the attendees realized how they could apply these new skills to current and future projects.

This training was solely in ROS 2 Humble. On the first day the attendees were split into two groups: beginner ROS developers and advanced ROS developers. The beginner group focused on learning the fundamentals of ROS, covering workspaces, publisher/subscribers, services, and launch files. The advanced group learned about motion planning with Tesseract. On day 2 the groups came together to learn about creating URDF/XACROs to describe a robot, and using Moveit2 for motion planning in a simulated environment. The third and final day contained attendees working through the Perception Driven Manipulation Demo and moving a real-world robot.

All instructions for the ROS Industrial Training are available online. The template and solution code can be found on the ROS-Industrial github.

Special thanks to Spirit AeroSystems for enabling this training to be held at NIAR/WSU and thanks to NIAR for providing the Universal Robot for the laboratory exercises.

Next training will be in October, so stay tuned to the ROSindustrial.org events page for those details as they are finalized!

Exploring ROS2 Basics: Training at Mitsubishi Electric Nagoya Works

Recently, our consortium conducted a comprehensive ROS2 Basics training session at the Mitsubishi Electric Nagoya Works Factory Automation Centre in Japan, from May 14th to 17th . This training brought together our consortium members from IHI, Mitsubishi Electric, Pepperl+Fuchs, and Panasonic,as well as the training team from RIC-AP (Glenn Tan, Adriel Ho, Sheila Suppiah), all eager to delve into the topics of ROS2 Basics.

The sessions covered essential topics including the publisher/subscriber model, service client model, launch files, and parameter tuning in ROS2. A significant focus was also placed on comparing ROS1 and ROS2, highlighting the advancements and improvements in the latter.

To ensure a solid foundation, the course began with an introduction to the Linux operating system and command line interface, which is essential for ROS2 development. The engagement from our consortium members was great, with active participation and thoughtful questions that contributed to a vibrant learning environment. Their enthusiasm underscores a shared commitment to advancing robotics through ROS based technologies.

As part of their final assessment, students applied their newfound knowledge in a practical application focusing on the usage of a TurtleBot3 Burger. This hands-on approach allowed them to demonstrate their understanding of ROS2 concepts in a real-world context, further solidifying their learning.

The feedback from participants was generally positive, with many expressing their interest to delve deeper into more advanced ROS topics in the future. We also had the opportunity to further enrich the learning experience, as we concluded the training with an insightful factory tour of Mitsubishi Electric.

This training session wouldn't have been possible without the continuous support and dedication of our consortium members. Their unwavering interest in ROS2 is paving the way for future advancements in robotics, demonstrating the power of collaboration in driving innovation forward.

We look forward to our next run of trainings in Japan! Do drop a comment or contact us if you are interested to participate in subsequent runs. #goROS

Robotic Blending Milestone 5 Wraps Up on the Foundry Shop Floor

On March 7, 2024, the Robotic Blending Milestone 5 team convened in West Jefferson, Ohio, at Fisher Cast Steel to see a demonstration of a Scan-N-Plan framework, optimized for a foundry system, that has an operational goal of grinding riser and gate surface anomalies to finished surface tolerances. The idea is to provide a system that is operator-driven and requires no interaction with the traditional robotic teach pendant. Through the use of intuitive user interfaces, the system should be able to work from simple operator cues to process parts to their desired finish state.

Workflow including Isu developed capability

Launched in March 2023, the program was built around a team that included sponsor Steel Founders’ Society of America (SFSA), Iowa State University (ISU), Yaskawa Motoman, PushCorp and Southwest Research Institute (SwRI). The program would leverage legacy ROS-Industrial Scan-N-Plan developments over the course of prior Focused Technical Projects (FTP) developed via the ROS-Industrial Consortium, as well as university developed capabilities at ISU, funded previously by SFSA. The combined capability may be seen in the below graphic.

The program held workshops and integration events at multiple team member sites. The first was a process development workshop hosted by PushCorp in their process development lab in Garland, Texas. Fisher Cast Steel provided samples for each team to utilize for testing and PushCorp provided guidance on how best to set up their spindle and active compliance device.

From there a starting system, with minimal Scan-N-Plan framework was instantiated in the lab at SwRI. This was largely based on the Scan-N-Plan Workshop which has been the basis for some of the recent trainings relative to industrial reconstruction and motion planning pipeline tuning.

Process development at pushcorp

From this point after a virtual demonstration in the SwRI lab, work got going in the Iowa State lab. ISU had installed a robust Kawasaki industrial robot with a similar but different PushCorp active compliance/spindle combination. One of the goals of this program was to create the same software implementations at each site on their specific configurations. This would enable ISU to develop add-on capabilities and test them in their lab and then update the main application to enable incorporation into the end user foundry site for evaluation and use. The software framework for the program and the modules to be updated and contributed by ISU are pictured below.

ISU hosted an integration event and the team worked together to assist ISU in updating their prior work from ROS Kinetic to ROS 2 Humble. Also, there were numerous working sessions to get a reliable ROS 2 driver and on robot interface for the PushCorp hardware working on their system. By the time the demonstration came around at ISU they had a working Scan-N-Plan system and had gotten tool path planning, and new concepts for approaches for grinding stone media working. This would end up being the prime path moving forward relative to the target castings for the program.

Though we did not get all the ISU capability incorporated, the team continued to work on the ISU segmentation approach and the program at ISU continues to work and test a more recent version. The participation of the students highlighted the opportunity for collaboration of grad school programs with more seasoned programmers to establish the foundational tools needed to enable students to come up to speed on complex ROS-based systems and how to sustain the talent pipeline.

Finally, the Yaskawa Motoman team completed their build and integration activities. The team came together quickly at Fisher Cast Steel to get the system ready for ROS-based capability deployment. Safety issues were resolved and cable management and PushCorp equipment integration was further optimized. Once the system was ready, the SwRI team deployed to the industrial PC via developed Docker images the full application, executed camera calibration and started initial testing.

By the mid-point of the second week the system was regularly grinding castings. It became evident that process optimization and development would be required. Due to the human-drawn boundary segmentation not being ready, the user selects a region of interest to do the grinding on the UI by simply circling it on the reconstruction in the view. The industrial reconstruction provides nice contrast and human markings show up clearly to assist in the process.

The full team convened for the demonstration on March 7, 2024. A number of features were processed, and the system demonstrated, even with region selection from the GUI to efficiently process only within the region of interest. There have been several areas for improvement identified, but the team felt a lot was learned and the system can deliver value. Fisher Cast Steel has since done a number of process enhancements and continues to improve system performance while also training operators to run the system independently. A number of enhancements to the open source Scan-N-Plan_workshop have been pushed and a blog post details those improvements in detail. A highlight video of the program is slated for later release.

Thanks to the full team for their work on realizing this capability at Fisher Cast Steel. This program highlights the value of bringing university partners together with robotic system deployers and solution providers along with sound software practices to realize compelling capability and provide pathways for funded university research to get more efficiently into operational environments. Thanks to the program sponsor Steel Founders’ Society of America for being the champion for this program and thanks to Fisher Cast Steel for their continued enthusiasm and feedback to continue to improve the delivered system which will further benefit others down the road.

Open Source Improvements from Recently Completed Robotic Blending M5

A Focused Technical Project (FTP), championed by the Steel Founders’ Society of America (SFSA), sponsored by the DLA-Troop Support, Philadelphia, PA, and the Defense Logistics Agency Information Operations, J68, Research & Development, Ft. Belvoir, VA, within the ROS-Industrial Consortium (RIC), has recently completed the Focused Technical Project (FTP) Robotic Blending Milestone 5. The team included RIC team members consisting of Yaskawa America, PushCorp and Southwest Research Institute, along with SFSA member university, Iowa State University. This work culminated in a deployed system at a SFSA member foundry site.

The project built on the prior Robotic Blending Milestone 4, which demonstrated high-mix material surface finishing and edge processing of arbitrarily shaped and contouring parts, largely targeting piece-parts to be welded. This work sought to extend that work, adding new features and incorporating additional SFSA funded work to realize human in the loop high-mix casting finishing for foundry operations.

During the development process, we have contributed the following improvements to the foundational Scan-N-Plan framework that served as a starting point for the FTP. This framework is maintained as a workshop repository within the RIC GitHub repository and is used in whole or in parts for developer instruction in ROS 2 for industrial robotics.

Scan-N-Plan Updates

ROS 2 Control:

We have added ros2_control code to the Scan-N-Plan example implementations to preview the robot’s motion during a simulated motion execution.

Constant TCP Velocity Time Parameterization:

We have added a time parameterization algorithm for maintaining constant TCP speed during motion planning. The approach works by first calculating forward kinematics at each trajectory waypoint to get the pose of the TCP. Then, we create a line path between adjacent TCP poses and parameterize the line with a trapezoidal velocity profile. The joint velocity and acceleration at each waypoint are computed given the TCP Cartesian velocity and acceleration. These obtained velocities and accelerations are then validated to be within the limits of the robot.

Docker Images:

To make the deployment and development of Scan-N-Plan more efficient and standardized, we have created Docker images for ROS 2 Foxy, Humble, and Rolling that can be found here.

Selectable Representation for Collision Object:

In addition to the default behavior of converting the scan mesh into a convex hull, the collision object can now be represented as a detailed mesh or as an octree.

Default behavior: Converts the scan mesh into a convex hull. This generally results in the fastest motion plans, especially with TrajOpt, but can be too conservative and may cause motion planning failures if the scan object is not actually convex or nearly convex.

Convex Hull Representation of Collision Object

Mesh: Represents the collision object as the exact “detailed” mesh represented by the mesh file. With the contact test type CLOSEST for TrajOpt, this representation results in a somewhat slower planning time than convex_mesh, but not significantly longer.

Mesh Representation of Collision Object

Octree: Represents the collision object as an octree comprised of spheres with a diameter specified by the octree_resolution parameter. With the contact test type CLOSEST for TrajOpt, this representation results in slightly faster planning times than mesh but slower than convex_mesh.

Octree Representation of Collision Object

Simplified Raster Planner

Simplified Raster Planner Widget

The parameters exposed in the raster planner GUI widget were modified to only show commonly tuned parameters during raster planning such as rotation offset (degrees), point spacing, line spacing, minimum segment length. This declutters the raster planner to improve usability.

Python Scanning and Execution Nodes

For ease of development and debugging during deployment efforts, we have converted the mesh reconstruction and motion execution simulator nodes from C++ to Python.

Service for Generating Scan Motion Plans

A separate service for generating scan motion plans has been made as an intermediate step to support creating dynamic scan trajectories in the future. This service will be called to create scan trajectory patterns that originate from a specified starting location.

Behavior Tree and Reactive GUI

The custom application back-end logic has been replaced with a behavior tree to improve workflow modularity and customizability. The behavior tree can change the GUI appearance based on the current behavior executed. Widgets are exposed and hidden during the workflow to guide the user’s focus to actions and settings relevant to the process at hand. A progress bar and preview motion bar have been made more accessible to inform the user where they are in the process.

Noether Updates

Tool path and Mesh Visualization Tool

Mesh/Tool path Viewer Widget

When developing and debugging tool path and mesh modifiers, it is helpful to visualize the original tool path, the modified tool path, the original mesh, and the modified mesh. Previously, there was no way to view the unmodified sub-mesh after applying a mesh modifier.

We have added a widget in the Noether application to toggle the view of the mesh and tool path VTK objects. We replaced the concatenated mesh viewer using a vtkAssembly and using vtkSmartPointers instead of using raw pointers for internal objects.

From Left to Right: Modified Tool path and Modified Mesh, Modified Tool path and Original Mesh, Original Tool path and Original Mesh, Tool path Hidden and Modified Mesh

Approach and Departure Tool Paths

To better stay within selected regions during processing, we added linear approach and departure tool paths (see below for the linear approach tool path). A modified version of these tool paths (circular approach/departure) creates an approach/departure curve of specified radius.

Linear approach tool path modifier

Plane Projection Mesh Modifier

We added a mesh modifier that fits a plane to the input mesh using random sample consensus and projects the inlier points onto the plane. This modifier prevents tool paths from being generated on an unintended inner or outer surface near the edge of a complex part, where the desired processing surface should be flat.

We hope developers and those interested in experimenting with ROS 2 for their industrial robotics application development have found this resource helpful. If you have questions, comments, or have observed an issue, please do not hesitate to either engage with the ROS-Industrial community or leave an issue over at the GitHub repository.

Cartesian Waypoints with Tolerance in TrajOpt

When translating a robot trajectory from a motion plan in a ROS system to an actual executed motion, there is an inherent loss of precision. In general, trajectories are sent to a controller that adheres to the exact position and timing constraints to the best of its ability, but compromises must be made to execute the trajectory. Additionally, robots cannot achieve infinite precision in positional accuracy because the kinematics of the system cannot be known with infinite precision. We have participated in work to maximize position and velocity accuracy, but not every process requires this level of precision. The process planning component should match the level of precision required by the application, but, traditionally, motion planners work assuming infinite precision. That is why we have now introduced tolerance into our motion planning pipeline when using Cartesian waypoints in TrajOpt.

TrajOpt is an optimization-based motion planner that uses a seed trajectory along with costs and constraints to refine towards a better trajectory. This process typically involves avoiding collisions and smoothing the motion. Previously, whenever we specified a Cartesian waypoint, the tool frame needed to adhere to the desired waypoint exactly. The total error across all six degrees of freedom (6DOF) could deviate by 1e-4 meters/radians, or it would be considered a constraint violation. In applications where we allowed free rotation or motion about an axis, the coefficient associated with that constraint could be set to zero, but users were not able to set bounds on the motion. For example, a common ROS-I application would allow free rotation about the Z-axis, so we would set the last coefficient in our waypoint coefficient vector to zero. An example of this process can be seen in the Scan N Plan Workshop.

Both the extremely high precision requirements and all-or-nothing approach to 6DOF Cartesian freedom of motion do not fit most applications. Additionally, these tight constraints can often cause unnecessary motion planning failures when a small freedom of motion would enable success. With the new tolerance parameters available in TrajOpt, we can more closely match the requirements of the system while reducing the number of motion planning failures. Now available in the trajopt_default_plan_profile are various settings to tailor the various waypoint requirements to the system’s needs.

Below are two example gifs. The first shows a failed plan when no tolerance was allowed (except for free rotation about the z-axis), and the second example illustrates a successful plan when tolerance was enabled: 15 mm in X and Y, 1.5 mm in Z, and 0.01 radians in rotation around X and Y (again, free rotation about Z was allowed). Visually, these two motions look almost identical, and infinite precision would not be required for this buffing process. Using tolerance in this application will enable the robot systems to align with the process requirements and improve overall success at incorporating robotics into various processes.

RICA Community Meeting Puts a Bow on 2023 Developments

The ROS-Industrial Consortium Americas hosted a fourth quarter end of year Community Meeting that highlighted recent develoments and upcoming events for 2024.

Matt Robinson led off the meeting with programmatic updates and some of the findings from the recent roadmap workshops and highlighted that a roadmap revisit at the ROS-Industrial open source project level would be coming for 2024. Furthermore, updates on training, with a proposed schedule was shared along with the announcment of the ROS-Industrial Consortium 2024 Annual Meeting.

The 2024 edition of the RICA Annual Meeting will take place March 27-28 and include demonstrations and lab tours. There is also the oppportunity to consider some hands on workshop time and surveying of the membership will take place early in 2024 to nail down specific events and Annual Meeting content. The event listing will continued to be updated as details are firmed up.

New feature enabling submesh visualization in noether

For the technical portion of the program Michael Ripperger shared recent workshops and technical updates to various ROS-Industrial tools and resources. The first noted was REACH hihgligthed by the recent ROSCon 2023 workshop that took place in New Orleans. There are now two working demos included in the workshop repository, which will eventually be moved to the ROS-Industrial GitHub organization. This workshop may be offered as a stand alone workshop or as part of an existing ROS-I training event.

Next, Michael shared a recent enhancement to noether, the tool path planning repository within ROS-Industrial. For some time, noether has supported region selection and application of tool paths within a selected region. However, it was not able to provide a visualization of that sub-mesh. Visualizations of sub-meshes has recently been merged and this enables both an improved visualization experience for an end user, but also the means to more thoroughly understand how an automated segmentation function is performing during the application development process. This is exactly the use case for the ROS-I Consortium Focused Technical Project Robotic Blending Milestone 5, where there is interest in applying tool paths in human drawn boundaries.

Tool path tolerancing to enable improve trajopt performance

Tyler Marr then dove into recent developments within Tesseract and in particular TrajOpt. The first update was the ability to use custom tasks in Tesseract motion planning pipelines. Tyler provided a couple examples in the presentation and provided a URL reference in how this is used in the Scan-N-Plan workshop.

From here Tyler covered the ability to apply Cartesian tolerance waypoints for Trajopt. Historically, Trajopt would simply attempt to find a solution for a proivded tool path or set of way points wihtout understanding what additional flexibility may be available. By enabling the application of tolerances in x,y,z, roll, pitch, and possibly free rotation around z, trajopt has greater liklihood of finding a solution. In the recording there are comparison screen casts of before and after leveraging this feature. It is anticipated this will enable a greater array of more complex tool path presentations to be solved via Trajopt. This is currently a pull request, but it is anticipated to be merged before the end of '23.

Overview of sword - ROS-I planning tools in a CAD environment

Michael wrapped up the technical session with an update on SWORD, the ROS-I planning tool that operates in a CAD environment. An alpha release is planned in early January 2024, with a website and the ability to experiment with a trial version. If you have interest in experimenting with SWORD, feel free to contact any of the ROS-I Americas team.

Thanks to all those that made this meeting. You can find the presentation material here and over at the event listing. The recording is linked directly and can be found at the ROS-I YouTube Channel.

As always reach out if there are questions or if you are interested in contributing or being involved wiht the ROS-Industrial open source project or the Consortium. Have a great end of year and start to 2024 and as always thank you for your interest and support in open source for industry.

Shaping Future Roboticists: Highlights from the ROS-Industrial Bootcamp 2023

The ROS-Industrial Bootcamp 2023 recently concluded, marking another successful chapter in our ongoing commitment to nurturing the next generation of robotic innovators. This 4-day highly anticipated event, held from October 2nd to 5th, brought together 24 aspiring Roboticists from three Institutes of Higher Learning: Ngee Ann Polytechnic (NP), Singapore Polytechnic (SP), and Singapore University of Technology and Design (SUTD).

Since its inception in 2017, the ROS-Industrial Bootcamp has been a cornerstone of our mission to equip students with essential knowledge in Robot Operating System (ROS) before embarking on their final year of studies or internships. The 4-day intensive program is designed to bridge the gap between theory and practical application, ensuring that participants are well-prepared for the challenges that lie ahead.

The bootcamp commenced with a foundational session on the fundamental principles of ROS, expertly led by Vinu from SUTD. During this session, participants delved deep into the core concepts of ROS, gaining profound insights into its pivotal role within the realm of robotics.

On the second day, participants were introduced to the practical side of robotics. Collaborating with Weefa Robotics, a local startup specializing in educational robots, students had the unique opportunity to configure a robot, providing them with hands-on experience that is invaluable for their future endeavours.

The intensive 4-days program was packed with important ROS concepts. On day 1, students were provided with the basic knowledge of ROS. Manu, from SUTD provided a lecture on ROS

On the second day, the students were given the opportunity to configure a robot. This year, we engaged Weefa Robotics,a local startup specialising in education robot.

On the third day, the focus of the bootcamp shifted towards the exploration of advanced robotics applications that enable navigation for robots. Specifically, the day was centred around two crucial components: augmented reality and autonomous tracking. These in-depth sessions broadened the students' horizons while fostering an environment conducive to innovative thinking and problem-solving.

The highlight of the bootcamp on the final day was when students participated in a mini competition. Working in teams of two to three, they faced the challenge of guiding their robots through a maze in the fastest time. The competition brought together all the knowledge and skills acquired throughout the bootcamp, providing a platform for students to showcase their abilities.

We extend our warmest and most heartfelt congratulations to the exemplary champions who emerged victorious in the maze navigation challenge. Their remarkable achievements serve as a resounding testament to the unwavering dedication and extraordinary talent exhibited by our future robotic engineers.

At ROS-Industrial, we believe that events like the ROS-Industrial Bootcamp 2023 inspire young engineers to innovate and push the boundaries of robotics applications. As we look forward to the future, we remain committed to fostering the next generation of robotics pioneers who will undoubtedly shape the landscape of robotics and automation.

We would like to express our sincere appreciation to our esteemed trainers: Adriel, Shalman, Vinu (SUTD), Sheila, Fairuz, and our amazing interns - Yu Cheng, Gabriel, and Ryan. Your dedication and support have played a pivotal role in making this event a resounding success.

ROS-Industrial Consortium Americas September '23 Community Meeting

On September 21 ROS-I Consorium Americas hosted a community meeting where a number of topics were covered. The presentations have been made available and the recording may be found over at the ROS-I YouTube channel.

To kick things off I reviewed some Consortium initiatives. Most recently we have been addressing concerns around industrial_core. There have been comments on a ROS 2 support issue about porting of industrial_core. However, as pointed out on the GitHub repository we will not be porting industrial_core due to the desire to take advantange of advances in OEM provided external motion interfaces and new approaches in driver development such as ros2_control based drivers and the recent Yaskawa micro-ROS based driver.

The idea is that OEMs will see opportunity in engaging the ROS community by offering a driver they are comfortable supporting, therefore there are not issues relative to performance as OEM changes occur within their software stack. We look forward to following up with an updated industrial driver specification, and will keep the community engaged on progress on that front.

From there we covered a couple focused projects. You can catch all the details in the slides, but the Robotic Blending Milestone 5 Focused Technical Project was covered, as well as work and progress on SWORD.

The FTP has already resulted in numerous enhancements to scan_n_plan_workshop and will also realize improved capabilities in a few other supporting repos.

SWORD came about as manufacturing engineering stakeholders continued to request ease of use tools, that also enabled greater ties to the CAD environmetn. SWORD seeks to provide, via a plug-in to FreeCAD, a simple UI for end-users to set up work cells and do various types of motion planning and motion tuning operations. We look forward to showing more, beyond what is in this deck or this deck, of SWORD in the coming months.

For the guest speaker at the meeting we were excited to have Pablo Garrido Sanchez from eProsima on board to share the latest around micro-ROS and supporting advanced ROS 2 deployments on microcontrollers and similar resource constrained devices. Check out his deck also included here and on the event page, as well as his full talk on the ROS-I YouTube channel.

Thanks to all those that attended and we look forward to hosting upcoming Developer Meetings and the Workshop at ROSCon. As always check out ros-i.org/events for the latest in chances to learn and collaborate with others excited about open source for industry.

10th Meeting of the ROS-Industrial Consortium Americas highlights reaffirming of the mission

On May 25 in Detroit the ROS-Industrial Consortium Americas (RICA) held the 10th iteration of the annual meeting, where Consortium members can get together, learn from each other, assess the state of the ROS-Industrial open-source project and provide feedback and engage in guided discussions, all with the intent of providing a two way interaction to understand the state and happenings relative to ROS-I and to provide their needs and areas for improvement.

A few wrinkles were included in this year’s edition. First, during the opening talk around the state of the Americas Consortium Shaun Edwards offered insights and thoughts relative to the beginnings and what we should be possibly considering looking forward.

The morning program continued with regional updates, including recent work by ROS-I Consortium EU seeking to instantiate a ROS 2 reference work cell, and highlighted recent contributions and plans to realize their vision. ROS-I Consortium AP shared their recent efforts to realize system level capabilities stemming from their extensive work around the interoperability framework Open RMF.

Kat Scott of Intrinsic shared the latest features included in the recent Iron Irwini ROS 2 release which happened only days before. A number of features highlighted include inclusion of REP-2012 Service Introspection, which is sort of a ‘ROS debug mode’ for understanding service calls and their results. Also, pre and post parameter callback, to enable parameter lists on the fly, and external logger configuration to enable only one node in verbose mode if you choose, as well as improvements in launch, rclcpp, rcl, and CLI.

Dave Coleman of PickNik shared the latest developments around MoveIt Studio and their recent efforts in support of SpaceROS with some key highlights that drive relevancy for industry, such as code quality and reliability.

To wrap up the morning session David Poweleit of the Steel Founders’ Society of America (SFSA) shared their recent initiative to sponsor a collaboration project across a diverse team including Yaskawa Motoman, PushCorp, Iowa State University, Southwest Research Institute, EWI, and ARIS Technology. The intent is to build on prior Scan-N-Plan collaborative efforts, referred to as Robotic Blending which had been through 4 prior milestones, to realize a prototype job shop system to enable high mix low-lot foundry finishing. This served as a lead-in for the broader goal and mission around the SFSA and their members relative to enabling funded research to get into foundries more efficiently.

From here Keynote speaker Shane Whitaker, Applications Engineer at Lockheed Martin, shared how and why their team has chosen to leverage ROS and open source in their pursuit of advanced capability. The value proposition for the nature of the operations is around the realization of operational agility for their environments and the nature of the tasks they need to get done to produce the products in their factories. The number of processes of interest and developed, leveraging open source, were broad, and it was inspiring to understand that these developments are making a difference on the floors of Lockheed Martin factories.

Shane Whitaker from Lockheed Martin shares their Agile Automation journey and how ROS has made an impact for their operations

New for this iteration of the annual meeting was offering externally guided workshop time. Per past annual meetings we spend time discussing what is within ROS-I, seek to drive conversations to understand what those that are looking for capability need, both with regards to capabilities and resources to enable their success. A lot of feedback was gathered, and some really interesting insights were shared. A more formal report on feedback will be coming soon.

The additional workshops were led by David Poweleit of SFSA and Adam Norton of the Nerve Center at University of Massachusetts Lowell. David led a dialog, largely centered around the SFSA members that were in attendance, but also solicited great responses from other general industry members that have similar challenges as the foundry industry. Technology developers also engaged, asking about requirements, the desired types of capabilities, and means to operate.

Adam Norton along with colleague Berk Calli of Worcester Polytechnic University led a conversation around their National Science Foundation funded work on Pathways to Enable Open-Source Ecosystems starting with Open-Source Robotic Manipulation and Benchmarking: Current Gaps and Future Solutions. The scope was broad as it covered open-source assets, such as software, designs of physical robotic components and systems, datasets that support AI/ML, and instructional elements that enable benchmarking of various components. The goal is to drive a discussion on what is missing and how can we better assess and continue to grow leverageable open-source assets and compare them to sustain a future where open-source plays a key role in innovative development. You can learn more about this initiative via this handout and the presentation shared at the workshop.

Diving into the afternoon Bharath Rao, Senior Research Lead at Spirit AeroSystems, covered their vision for sustained deployment of advanced systems and solutions for entire value stream monitor and control across many assets, some human driven, others if not autonomous a future where they are. Bharath laid out a compelling vision for how a manufacturing entity may leverage open-source to realize a vision over incremental capability introduction that grows with testing, validation and improvement.

Dr. Eugen Solowjow, Head of Research at Siemens Berkeley, shared the recent work within Siemens to enable AI for robotics and how they are delivering products that enable AI solutions to run on and interoperate with traditional industrial hardware, such as PLCs.

The latter part of the afternoon included the latest in improved motion profile accuracy at high speeds for complex 3D curves presented by Dr. John Wen of Rensselaer Polytechnic Institute. This work has been really exciting for those that want to leverage autonomous motion planning but struggle with how the actual manipulator turns the sent trajectories into real motion. The two-step process includes a redundancy resolution algorithm that filters and adjusts the input target tool path and then leverages a reinforcement learning approach to further tune the manipulator that may be done on hardware via a handful of dry runs or in the OEM simulation engine if it accurately represents the physics. These tools have been provided in the RPI open-source repositories and have been developed in the course of an ARM Institute project.

Wrapping up the day, Joseph Giampappa of the ARM Institute provided an update on the latest initiatives within the ARM Institute, and the day concluded with Ted Miller of Yaskawa Motoman announcing the official release of MotoROS2. This is the latest in ROS 2 support in the industrial manipulator domain and the first where the ROS 2 node actually runs on the robot controller.

Looking back, it was a great week in Detroit and a great day spent with all the organizations, collaborators and individual developers seeking to make open-source for industry a leverageable resource for innovation in industrial settings. The continued development and latest work taking place both in the open-source and within the organizations that are leveraging open-source and making contributions, are building on the legacy and enabling new players to deliver novel new solutions. This brick-by-brick approach enables broader opportunities for innovation while enabling educational resources for future roboticists.

Americas Puts on Updated ROS 2 Training with Revamped Motion Panning Special Topic

This July, Southwest Research Institute (SwRI) hosted the most recent ROS Industrial training workshop. A large group came in from around the Americas region to learn a mix of ROS 2 fundamentals and advanced topics, as well as explore the city of San Antonio.

ROS-I trainers and students gathered to enjoy dinner out in San Antonio

To start the workshop, beginner students worked through the basics of ROS 2, while those already familiar with ROS were walked through our freshly updated exercise on performing motion planning with Tesseract. All students then came together to learn about setting up their robot URDF, do motion planning with MoveIt, and process pointclouds using PCL. Notably, these students were the first to experience the ROS-I training fully in ROS 2 Humble. No more spending time during training wrapping your mind around ROSbouncing between ROS 1 and ROS 2 1 just to get MoveIt up and running.

The students were also given a tour of Southwest Research Institute’s robotics facilities, where they got to see what they were learning in action. SwRI demonstrated a scan-n-plan application that utilized the ideas of motion planning and perception taught during training.

ROS-Industrial celebrates 10 years of uniting researchers and industry to solve industrial automation challenges with open-source software

Industrial robotics has changed dramatically from a decade ago, when a small group of researchers held the first annual meeting of the ROS-Industrial Consortium. Back then, much of the robotics research happening in university and corporate labs would languish in papers because it was difficult to replicate custom implementations using proprietary software.

Things started to change when the Robot Operating System (ROS) – an open-source software platform founded in 2007 by Willow Garage, the Stanford AI Laboratory, and Open Robotics – started reappearing in research papers. ROS helped open the door to R&D scalability across industry and academia, enabling a means to abstract robotics hardware, while also bringing a modularity and notion of abstraction and reproducibility to the robotic research space.

ROS caught the attention of a group of leading robotics companies and research institutions, including Yaskawa Motoman and Southwest Research Institute (SwRI). They teamed up with Willow Garage and founded the ROS-Industrial Consortium (ROS-I), which held its first annual meeting in 2013. On May 25 of 2023, the ROS-Industrial Consortium celebrates its 10th Anniversary.

In 2013, when ROS-Industrial held its first meeting at SwRI in San Antonio, there were 14 member organizations. Today, membership has expanded to over 85 organizations representing a broad range of industries and academic institutions.

The First ROS-I Consortium Gathering March 2013

How ROS-I Harnessed the Potential of Open-Source for Industry

The ROS-Industrial founding organizations saw the potential of open-source robotics technologies to revolutionize the manufacturing industry, and they came together to create a platform that would enable the development and deployment of these technologies in a cost-effective and efficient manner. ROS-I sought to bring more advanced computer science tools and standard path planning/motion planning libraries that were not sole propriety of the robot manufacturer. This confluence enabled investigation of a new approach to industrial robotics and a chance to set a path towards new capability that was not either only in a research lab or only available via one robot manufacturer.

Shortly after the founding of ROS-I, that first commit by SwRI’s Shaun Edwards and Paul Hvass—with the support of SwRI’s Paul Evans and Clay Flannigan—launched the ROS-Industrial Consortium. It wasn’t long before Fraunhofer IPA in Germany and the Advanced Remanufacturing Technology Centre in Singapore launched collaborative ROS-Industrial Consortia for the European Union and Asia-Pacific regions. Their energy and ingenuity have made Consortium growth and management such a fruitful experience.

Since that time the Consortia, via collaboration and engagement with industry, have made significant progress towards the goal of accelerating the development and adoption of open-source robotics technologies for industrial applications. Some of the consortium's key accomplishments include:

• Developing a comprehensive set of software tools and libraries that enable the use of ROS for industrial applications.
• Creating a vibrant community of ROS users and developers in the industrial robotics space.
• Conducting several successful Focused Technical Projects (FTPs) that have developed new capabilities for ROS-I.
• Working with leading robotics companies and research institutions to promote the use of ROS for industrial applications.

Growing ROS-I by Improving Standardization & Expansion

Shaun and Paul have since benefitted since joining and leading Plus One Robotics while also continuing to be stewards and champions for open-source collaborative development.

Shaun provided his take on what he has seen from the start of the ROS-I Consortium and what it has enabled: “In the very beginning of ROS-I, we found ourselves defending the robustness and reliability of open-source software. Only time would demonstrate that ROS could be as robust and reliable as commercial software as it was adopted across industrial and commercial robotics. Those companies with existing robot software stacks were not able to wholesale switch to ROS. Instead, they created integrations with ROS, while mimicking features of ROS that users found compelling (e.g. rich visualizations, physics simulation, and advanced computer vision). End users with complex and dynamic robot processes found ROS was necessary in order to build advanced solution. One such example was the ROS-Industrial Scan-N-Plan project(s). Scan-N-Plan leads to deployments at end users and was later followed by several startups who productized similar technologies for welding (Path Robotics) and sanding (GreyMatter). In addition to those examples, many startups without existing software stacks, were free to start with ROS as the core of their product offering. Plus One Robotics, Fetch Robotics, Renu Robotics, and Amp Robotics are just of few of hundreds. These companies have gone on to solve valuable problems and become respectable robot companies.”

Though a lot of progress has been made, there is still a role for a consortium that fosters collaboration between the open-source community, industry, and academia. Recently it has become very clear that standardization of various interfaces, communication standards, and modeling is lacking, manifesting in numerous translation efforts and frustration when multiple protocols are required within one application. Numerous working groups are in progress to investigate these, and the ROS-I Consortium has played a role in providing input to drive an industry perspective.

Shaun took the time to add his take on what the Consortium can contribute moving forward: “The consortium speaks with a louder voice today than ever before. It should use this new standing to expand its footprint. There remain many challenges in robotics today that could be addressed by cooperative research in the vein of Scan-N-Plan and other consortium projects.”

Shaun added that, “Expansion beyond robotics should also be considered. There are more open standards and open software in industrial automation today than ever before. An advanced robot cell contains robots, PLCs, and HMIs, as well as links to the cloud for analytics and planning. All these aspects have a software component that already have or could have has open-source alternatives. Just as ROS is now firmly a part of industrial robotics, the ROS-Industrial Consortium could usher in the age of open source for the entire factory.”

The Next Decade: Building Community & Integrating AI

ROS-I is well-positioned to continue to accelerate the pace of advanced robotics for industry in the years to come. The consortium has a strong track record of success, and it has a vibrant community of users and developers who are committed to the advancement of open-source robotics technologies. In addition, ROS-I is working with leading robotics companies and research institutions to promote the use of ROS for industrial applications. ROS-Industrial seeks to enable efficient incorporation of Artificial Intelligence in its various forms, and supporting commercial entities that seek to streamline the ease of use for robotics and AI together.

The ROS-I Consortium will continue to work towards providing value not only to its members, but also to the open-source robotics community. This includes example applications, helping to make open-source robotics technologies more accessible and affordable, and it is enabling the development of new and innovative industrial capability that can improve productivity, safety, and quality.

We look forward to collaborating with the robotics community more broadly to enable more end-users to solve their complex challenges in an efficient way and provide the means to entrepreneurs to have bankable new tools for which to address the needs of their target market. At this, the 10-year anniversary of the Americas Consortium meeting where members gather to share the latest in open source for industry, we will seek pathways to continue this mission. The ROS-I Consortium has enjoyed providing the foundation and we look forward to continuing to enable the industrial robotics solutions for tomorrow.

For remote attendees live streaming of talks has been a tradition and was made available and recordings of the sessions will be available in the future.

The basics of getting up and running with ROS 2 in Windows

Development in ROS used to only be able to be done in Linux, with Ubuntu being the only fully supported operating system. With ROS 2, more options have opened up to support ROS development. In this blog post, we’ll discuss how you can get ROS 2 up and running on the Windows.

Why use ROS 2 in Windows?

There are a number of reasons you may wish to pursue ROS development in Windows.

• You or a client are limited in available operating systems
• You want to utilize applications/libraries that are only supported in Windows
• You are much more comfortable with Windows development over Linux development

Why not use ROS 2 in Windows?

While there are good reasons to use ROS in Windows, the reasons against it are substantial:

• ROS 2 packages are still typically developed with Linux in mind, and often don’t build without
• modification
• ROS in Windows is generally less supported and complete than it is in Linux.
• You will have more trouble finding solutions for any problems that come up
• More unexpected issues are likely to pop up than in Linux
• ROS behaviors are not entirely consistent between operating systems

RVIz launching in windows

What are my options?

The simplest option to using ROS 2 in Windows is to avoid using Windows as much as possible by using Windows Subsystem for Linux (WSL). WSL operates a Linux kernel on top of the already running Windows kernel, allowing it to execute programs meant for Linux while within Windows. This is much more lightweight than a full virtual machine and allows easy access to files located within your Windows system. Head here (https://learn.microsoft.com/en-us/windows/wsl/install) to get started with WSL.

>A second option is to use a fully pre-built package from the chocolatey package manager. This will streamline the installation process to a few copy-paste commands and greatly reduces the likelihood of errors occurring in the installation process (which can be non-trivial to debug). aka.ms/ros hosts a package for ROS 2 foxy, with instructions available here (https://ms-iot.github.io/ROSOnWindows/GettingStarted/SetupRos2.html)

A final option if you really need a version that is not installable as a full package via chocolatey is to follow the installation instructions for that distro from the ROS 2 docs (https://docs.ros.org/en/humble/Installation/Windows-Install-Binary.html). There are a large number of steps that are far more prone to error, and since Windows is not as well supported, these instructions are more likely to be out of date themselves.

Working with ROS in Windows:

If you choose to use WSL, then congratulations! You don’t have anything new to learn. You have access to a bash shell with all the usual ROS 2 commands you know and love. Simply start your WSL instance and you’re good to go.

If you are truly only using Windows, you will be working within a Powershell or Command Prompt window, which will work with their own commands for you to learn instead of bash. Make sure to call the appropriate setup.ps1 or setup.bat for the terminal you are using, and expect to modify the Cmake for any ROS projects that you are building from source. A few other considerations are listed here (https://docs.ros.org/en/foxy/The-ROS2-Project/Contributing/Windows-Tips-and-Tricks.html)

Conclusion

While it is recommended to stick with Linux for your ROS development, you have options to continue your applications in Windows. There are some extra limitations and difficulties, but once you get past the initial pains, the development process is largely the same.

ROS-Industrial Focused Technical Project Robotic Blending Milestone 5 Launches

The ROS-Industrial Consortium, championed by the Steel Founders’ Society of America (SFSA), has launched the Focused Technical Project (FTP) Robotic Blending Milestone 5. This builds on the prior Robotic Blending Milestone 4, which demonstrated high-mix material surface finishing and edge processing of arbitrarily shaped and contouring parts, largely targeting piece-parts to be welded.

In this new milestone, launched in March, the key goal is to place a working system at an SFSA member foundry site, and enable that end-user to leverage the CAD free, entirely perception-driven system to remove unwanted surface features due to casting pour process and finish the total surface area for subsequent inspection and ship to the client.

To make this FTP a reality, a diverse team provided various forms of contribution to enable successful application development, core capability implementation, testing, and a pathway to replication for additional foundries. This team consists of champion SFSA, Southwest Research Institute (SwRI), Yaskawa America, PushCorp, Iowa State University (ISU), deployment foundry Fisher Cast Steel, and in-kind team members ARIS Technology and Edison Welding Institute.

As is the case in prior FTP efforts, there will be multiple integration events that enable cross-team collaboration and will leave functioning capability at partner sites. In this case with partner university ISU, which will integrate recently developed capability, host a collaborative integration event, while learning the blending framework. SFSA has a long history of working with ISU and a key milestone will be implementing into the Scan-N-Plan framework recently developed riser removal perception driven finishing that has been demonstrated in the ISU lab. The goals of this integration of the ISU capability are to leave a functioning Scan-N-Plan system in the ISU lab to enable them to implement and test capabilities developed with SFSA and enable more efficient transfer to end-user sites that may adopt the Robotic Blending capability in the future.

The project completes with an integration event at the SFSA member, Fisher Cast Steel, and demonstration of capability on production cast parts. The removal surface irregularities due to riser removal will be evaluated across the parts as well as overall surface finishing to support surface inspection processes where required. A summary of core repositories that were improved will be detailed and a highlight video and supporting documentation will be provided. In-kind partners will have the opportunity to support additional end-users to adopt the capability and make further refinements on top of the core developed capability.

The ROS-Industrial Consortium, in collaboration with SFSA and the development team look forward to furthering advanced robotics capability for industry and to provide a pathway for foundries to adopt intelligent automation for high mix casting environments.

What Went Down in the April ROS-I Developers' Meeting

On April 11 we held the ROS-I Developers’ Meeting. For those that haven’t checked one of these out, this is a gathering of developer-centric folks that are interested in hearing what is in development within the ROS-I ecosystem, what new resources may be available, and have some dialog on issues and/or areas for potential collaboration. This edition was hosted by the Americas ROS-I team, and we were fortunate to have three updates after a brief introduction.

• Doug Smith shared work around OPC-UA and how to take advantage of this standard to enable PLC to ROS-based system interaction. Doug provided a few resources and shared a couple reference repos.

The meeting wrapped up around some great discussion around the FreeCAD ROS plug-in that has been in Beta informed by feedback from the ROS-Industrial end-user and developer community. Updates are coming and we appreciate the feedback and interest from the community to date. You can check out the full discussion in the video below and feel free to review the slides here. ROS-I Developer meetings are held monthly on a regional rotation basis. You can see the full schedule and register for each region here.

ROS 2 Training Event Hosted by RPI Featuring New Advanced Topic

At the start of March, Tiffany Cappellari, my colleague, and I made our way to Rensselaer Polytechnic Institute in Troy NY, to deliver ROS2 Training to members of our ROS-Industrial community. Rensselaer Polytechnic, in addition to being a prestigious academic institution, has been a proud partner in project work with many other ROS-Industrial Consortium members, collaborators, and those in need of more advanced capability. RPI kindly hosted our first in-person training of calendar year 2023.

Tiffany Cappellari introduced the experienced students to a new motion planning pipeline exercise utilizing the Tesseract toolbox while I introduced the fundamentals of ROS 2 to engineers and developers of a wide range of experience levels. All our attendees were able to explore a variety of capabilities and packages for motion planning, perception, and image processing, either native to ROS 2 or hosted by ROS-Industrial's many open-source toolbox repositories.

Workshop attendees included graduate students, mechanical engineers, software developers, and project managers that together were enabled to discuss, in context, how the training tools can be applied to their systems and processes. For participants familiar with ROS 1, our in-person discussions included porting best-practices and lessons learned about the framework & operational differences between the two. Our exercise-based fundamentals course begins the development of a basic ROS workspace and setting up basic ROS packages for incorporation into other projects. From there, all trainees construct URDFs, basic motion planning packages using MoveIt, and Python script launch files to generate a robot workcell, plan and enact movements with that robot, and bring it all up through one, simple script.

Trainees also tried ‘Building a Perception Pipeline’, a special topic exercise that introduced several tools from Point Cloud Library (PCL) to filter and segment camera data for use in manipulation tasks. Our latest special topic, ‘Motion Planning with Tesseract’ highlighted the motion planning pipeline capabilities in Tesseract to create smooth, optimized trajectories.

RPI’s precocious graduate students kindly took us on a tour of their workspaces, including spaces where the Tesseract toolbox utilized for the special topic on motion planning is implemented on hardware.

All training materials can be found on the ROS-Industrial Training wiki, and they are updated regularly for new capabilities. Check out the github for a setup script used for a VM or Docker to get a head-start on system settings if you’re operating on an OS other than Ubuntu 20.04. We hope to see you at our next training event in July 2023 in San Antonio, TX!
