Abstract:
A method for an external force to drive a moving piece in a mechanical joint, wherein less force is used to drive the moving piece in the mechanical joint. The joint comprises a stationary piece, the moving piece and a driving mechanism ( 13 ), the driving mechanism comprises a servomotor ( 131 ), a driver ( 132 ) and an encoder ( 133 ), and the servomotor is connected to the moving piece. The driving method is: when the joint is in a stationary state, the servomotor is in a torque mode, and the servomotor outputs a resistance-reducing torque having a direction which changes with time; the external force is used to drive the moving piece, so that the moving piece moves with respect to the stationary piece; the driver determines the movement direction of the moving piece according to an output of the encoder; if the moving piece is moving in a positive direction with respect to the stationary piece, the servomotor is controlled to stop outpacing the resistance-reducing torque or output an assistance torque enabling the moving piece to have a positive direction movement trend; if the moving piece is moving in reverse with respect to the stationary piece, the servomotor is controlled to stop ontputting the resistance-reducing torque or output an assistance torque enabling the moving piece to have a reverse movement trend.

Claim (Index 3):
The method for an external force to drive a moving piece in a mechanical joint according to  claim 2 , wherein in step b, no matter the moving piece is moving in a positive direction or a negative direction with respect to the stationary piece, the servomotor is controlled through the driver to output the assistance torque, and the strength of the assistance torque is equal to or less than the value of the resistance-reducing torque when the moving piece starts to move with respect to the stationary piece.
