A stereoscopic theodolite measuring system is used to determine the three dimensional positioning accuracy of an industrial robot. The control of the theodolite movement and the robot movement, the image processing and the coordinate calculations were done by a host computer, which also processes the measuring data and communicates them by the local computer network. The spatial positioning accuracy of the robot is measured separately on translational and rotational axes.
