Abstract

The invention is suitable for the field of robots, and provides a robot motion error in-situ detection and compensation method and robot motion error in-situ detection and compensation equipment. The robot motion error in-situ detection method comprises the following steps that based on structural parameters of a standard part, a target motion track is generated; and a robot enables a measuring device to move along the target motion track, and in the process that the robot enables the measuring device to move along the target motion track, the actual motion error of the robot is obtained through detection of the measuring device. The motion track of the robot is compensated with error data to obtain the compensation motion track of the robot, then the motion error of the robot is restrained, and the robot motion precision is improved.
