Abstract
The present disclosure provides a transmission hysteresis detecting method and apparatus. The method includes: transmitting a forward rotational instruction and a reverse rotational instruction to a motor of the servo; storing motor end positions of the motor and output shaft end positions of an output shaft corresponding to the motor in a forward rotational cycle and a reverse rotational cycle, respectively; generating first position data based on the motor end positions and the corresponding output shaft end positions in the forward rotational cycle; generating second position data based on the motor end positions and the corresponding output shaft end positions in the reverse rotational cycle; and calculating a transmission hysteresis of the servo based on the first position data and the second position data. The technical solutions of the present disclosure only needs to obtain the position data of one forward rotational cycle and one reverse rotational cycle.
