Device and method for finding original point by utilizing torsion detection

The invention discloses a device and method for finding an original point by utilizing torsion detection. The device comprises an action mechanism, a motor connected with the action mechanism and usedfor driving the action mechanism to rotate, a driver and a controller. The motor is provided with an encoder for detecting the torsion of the motor; the driver is connected with the motor and the encoder and is used for receiving a torsion signal transmitted by the encoder so as to convert the torsion signal into a motor feedback value and driving the motor to work according to a control instruction; the controller is connected with the driver and is used for sending a corresponding control instruction to the driver according to the motor feedback value; and the controller is provided with aregister for setting a torque upper limit. The encoder is used for detecting the torque of the motor to act, so that the reliability is high. 本发明公开了一种利用扭力侦测寻原点的装置及方法，它包括动作机构；马达，所述马达与所述动作机构相连接，用于带动所述动作机构进行转动；所述马达具有侦测其扭力的编码器；驱动器
