Scan-N-Plan™
Scan-N-Plan technologies are a suite of tools that enable real-time robot trajectory planning from 3-D scan data. Traditional industrial robot programming is performed using either online, teach-pendant programming or offline programming with a simulated version of the robot and work piece. The Scan-N-Plan approach overcomes limitations in traditional robot programming for applications that:
- Have highly variable part mixes such that hand programming is impractical
- Do not have CAD part models available
- Include flexible or deformable parts such that pre-programming is impossible
- Have part-to-part variability that is difficult to accommodate with static programming
- Require flexible part fixturing or no fixturing at all
These applications are representative of adaptable and flexible operations that respond dynamically to changes in part geometry or presentation — all with little or no human intervention. In addition, the dynamic nature of the trajectory generation permits real-time adaptation based on process feedback.
Traditional robot programming requires an expert-in-the-loop, which limits responsiveness to changes in the process:
The Scan-N-Plan approach leverages 3D scanning techniques to generate the part geometry and location in realtime, eliminating the human in the loop and enabling agility:
Scan-N-Plan can be generalized to many different processes such as painting, surface finishing, deburring, inspection, and others. The ROS-Industrial Consortium is currently developing the technique for surface blending (sanding) and it has previously been deployed in robotic paint applications.

As part of EU-funded project ROSIN, Fraunhofer IPA made a Scan-N-Polish application together with ROS-Industrial Consortium member PILZ and showcased it on AUTOMATICA trade fair 2018 in Munich, Germany, as well as ROSCon and IROS 2018 in Madrid, Spain.
