The present disclosure provides a servo output shaft angle calibration method and a robot using the same. In the method, when a servo output shaft rotational angle calibration instruction is obtained, an output shaft of a servo is controlled to move in a preset rotational direction, a current angle of the output shaft of the servo is obtained when it detects that the output shaft of the servo has rotated to an end point and has a stalling, and then a preset end point angle is updated as the current angle of the output shaft of the servo, so as to take the current angle of the output shaft of the servo as the new end point angle, thereby realizing the calibration of the end point angle of the output shaft of the servo. In this manner, the entire calibration process requires no manual intervention.
