Using the characteristics of highprecision measurement of laser tracker,the robot rod lengths were measured directly and accurately by changing the robot’ s different pose. Compared with the results by using RoboDyn calibration software,the position accuracy of the tested robot was improved less notably than the latter. But the results by means of previous two ways were both improved a lot. The error resources of the rod length measured based on laser tracker were also analyzed. The experimental results show that the simple calibration method based on laser tracker is aconvenient and effective method.
