Research on fast field calibration method of industrial robot

Robot calibration is an important method to improve the accuracy of robot, and for the question about the complicated operation on parameter identification for Multiple Degree of Freedom in the process of the industrial robot calibration, Based on the Laser Tracker System and SA software, this article has developed a fast calibration method to identify the geometric parameters for robotic connecting rod, this method can be directly used to measure connecting rod geometry parameters of the robot without complicated operation on parameter identification, so it is more suitable for fast and precision calibration in industrial field. At the last of this paper, the effectiveness of experiment has been proved by the field testing on robot HSR-JR608. Experimental results show that this method can quickly raise the straightness of the robot.
