ConTrax Robotic System – a standard robot built on the base platform of the AGV. The AGV can travel along the optical track to different stations, either travelling forwards or backwards. At the workstation the robot’s gripper handles both the container and the workpiece.

The robot is positioned at the loading/unloading station via an optical referencing system. Every station is assigned a coordinate which is attached to a cube. The robot’s camera takes a picture and calculates the deviations in position of the AGV from the theoretical coordinate. Only one cube with a coordinate system is required at the loading/unloading station for this robust and simple solution. The deviation is calculated in approximately one second. All three spatial axes can be calculated subject to the requirements of the process. Workpiece accuracies of +/- 0.2 mm can therefore be achieved on the robot, regardless of the position of the AGV.
