The present disclosure is provides a servo control method as well as an apparatus and a robot using the same. The method includes: obtaining a teeth force reduction multiple of a gear of a servo; creating a voltage queue based on the teeth force reduction multiple; calculating a target loading voltage corresponding to a current moment based on a voltage queue; and applying the target loading voltage on a motor of the servo, wherein the target loading voltage is for driving the motor of the servo to rotate. Through the above-mentioned method, the loading voltage can be effectively reduced when the servo is started, thereby protecting teeth of the gear of the servo and increasing the service life of the servo.
