Abstract

See full text

The present disclosure relates to a kinematics calibration method for a robot with multiple degrees of freedom. The robot includes a base, an end effector, and a plurality of links connected by joints. The method includes locking part of the multiple degrees of freedom by limiting the base and the end effector impose a limitation of degree of freedom; moving the robot to perform a first movement and accordingly obtaining a first set of data associated with joint angles and a first actual motion of the end effector; calculating a first theoretical motion of the end effector based on the first set of data and initial kinematics parameters; and updating the initial kinematics parameters of the robot to obtain a first set of updated kinematics parameters based on the first theoretical motion and the first actual motion.
