Abstract

Accuracy measurement is an essential front step to error compensation of industrial robots. Different measurement methods have been tried all the way over the past years. In this paper, we propose a novel method to measure the positioning distance accuracy based on the multi-station technology of the laser tracer device. Compared with the laser tracker device, this method is more precise in measuring the coordinate values of the robot end-effector. Besides, the laser tracer is more portable than the laser tracker. At the last part, a practical example is presented in which we have carried out in an domestic industrial robot.
