METHOD FOR CONTROLLING ZERO-RETURN OF SERVO OF ROBOT, AND SERVO AND ROBOT WITH ENHANCED ZERO-RETURN

摘要

The present disclosure relates to a method for controlling zero-return of a servo of a robot, and a servo and a robot with enhanced zero-return. The method includes: outputting an activation command to a motor, and reading a default zero-point of the motor (w1) and a default zero-point of an output shaft of the speed reducer (w2). The output shaft of the motor (w1) is driven to return until the default zero-point of the output shaft of the speed reducer (w2) is the same with the current position of the output shaft of the speed reducer (w4) in response to the default zero-point of an output shaft of the speed reducer (w2) being not the same with the current position of the output shaft of the speed reducer (w4).
