Abstract


Conventional calibration of industrial robots is carried out with a use of special measurement equipment, which is expensive and it also requires skilled personnel to operate. This paper presents a methodology, which utilises a camera to perform measurements of position accuracy of a robot. The experiments were conducted with a KUKA robot and a coupled measuring arm, as well as an in-door GPS (iGPS) in order to compare the results. The accuracy obtained with the camera is in agreement with the robot accuracy, and is better than the error measurement results of the measuring arm and the iGPS. Hence, it is envisaged that this methodology, together with numerical optimisation, can be used for robot calibration.
