SummaryOriginally, industrial robots are used for painting, welding or handling, and don't need a good repeatability for those processes. Yet new 3D measuring systems tend to use robots for their speed, accessibility, wide work field and easy reprogramming, but they need more complex processes and trajectories.
The main goal is a 3D scan using a 6 axis robot to carry the measuring system. The challenge is to obtain better results than with existing scanning methods for robots, that is to say better accuracy, robustness and cycle time. Firstly a study on robot elastic-geometric model will be carried out. Then scan trajectories will be built with robot performances maps and scanning system performances. Finally a multi sensor dynamic measure will be investigated to solve deformation problem when large pieces are carried by the robot, and to reinforce measure robustness by monitoring the scanning process.
