Abstract: 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).

Abstract: A method for servo locking control is provided. A servo enters a first lock state, and determines whether the current angular deflection values of the servo in a first preset period are all greater than a preset angular deflection value. When the current angular deflection values of the servo in the first preset period are all greater than the preset angular deflection value, the servo enters a second lock state, and determines whether the current angular changing values of the servo in a second preset period are all less than a preset angular changing value. When the current angular changing values of the servo in the second preset period are all less than the preset angular changing value, the servo enters the first lock state. A servo for performing the method for servo locking control is also provided.
