Abstract: The present disclosure is an apparatus for testing an idle position of a servo, including: driving mechanism, a transmission unit transmitting torque of a driving servo to a testing servo, and a control circuit electrically connecting to the driving servo and the testing servo to acquire idle position information. The apparatus drives the output shaft of the testing servo to rotate by an external driving mechanism, and measures an amount of rotation of the output shaft by an internal sensor of the testing servo. Therefore, an external sensor may not be provided, and a problem of precision installation of the external sensor can be avoided. Further, a problem caused by poorly install the external sensor and the output shaft can also be avoided, and accuracy of a testing result can be increased.
