Pose repeatability is one of the important parameters of industrial robots. Repetitive accuracy testing system for robots is mainly used for Pose repeatability detection.The laser tracker is selected as the contrast instrument to verify the repetitive accuracy test system of the robot. According to the GB/T 12642-2013 Industrial robots performance criteria and related test methods, a periodic verification method was put forward for the repeatability of the robot pose of repetitive accuracy test system, which ensured the duration of the robot of repetitive accuracy test system. It can maintain the reliability of equipment calibration status and get the best measurement ability, so as to ensure and maintain credibility of the test results.
