Abstract
The present disclosure provides a robot servo jitter suppression method and device. The method includes: counting an amount of reciprocating jitter of an angular position of an output shaft of a robot servo in a predetermined period, after the robot servo enters a lock position state for a first predetermined period; determining whether the robot servo is in a jitter state according to the amount of the reciprocating jitter of the angular position of the output shaft of the robot servo and a predetermined fluctuation value; and suppressing the jitter of the robot servo by adjusting control parameter(s) of the robot servo, in response to the robot servo being in the jitter state. The robot servo jitter suppression method and device solve the problem of the jitter of the robot servo appears when the virtual positions of the robot servo and the robot joint structure are not properly controlled.
