Flexible mechanical arm control method and robot system

Abstract

A flexible mechanical arm control method and a robot system. The control method comprises steps of: obtaining a total amount of angular displacement of a joint output end of the flexible mechanical arm (110) along a first direction when a load on the joint output end changes; driving the joint output end to move in a second direction according to the total amount of angular displacement, so that the joint output end returns to a position and posture before the load changes; the second direction is opposite to the first direction. According to the method, the position and posture of the joint output end can be maintained when the load on the joint output end of the flexible mechanical arm (110) changes, so as to facilitate a doctor to execute predetermined surgical operation in the fixed position and posture.
