ABSTRACT:
In a force controlling system, a movable member fixed to an elastic member applies a force to an object in correspondence with a force reference signal. At this time, an additional force is applied via a driver to the movable member by the positive feedback of the displacement of the elastic member to the driver, so that the reactive force due to the displacement of the elastic member is counteracted by the additional force. As a result, the movable memer applies only a force in correspondence to the force reference signal to the object.
