Checking the accuracy of robot trajectories

The measurement of the trajectory accuracy or its reproducibility is carried out along a diagonal straight line in space. The robot moves the measuring head, which is fitted with sensors, along a steel rule. The deflection of the 2m long rule due to its own weight is compensated by software. Through the arrangement with six sensors both position and
orientation deviations are acquired simultaneously.
