Perceptron, Inc. announced receiving an order for nine AccuSite® optical tracking systems for precision robot guidance and metrology applications. In robot guidance applications no part is perfect, and no process is perfect; therefore, there are two goals to achieve optimal part placement. Goal one is removing the variation introduced by these two factors. To achieve this, Helix sensors are installed around the assembly to measure key locating features and then send an offset to the robot to correctly place the part in the assembly. Goal two is removing the variation caused by any changes in the robot due to temperature and mechanical drift. An AccuSite Star is mounted on the robot’s end-of-arm tooling and the AccuSite Tracker captures its precise position. Based on this measurement, a secondary offset is calculated and sent to the robot ensuring precise placement.
