Abstract
A force and torque converter provides an electronic signal in response to at least one of an applied force and an applied torque. The converter includes a base, a movable member that provides movement relative to the base in response to the at least one of the applied force and the applied torque, a controlling mechanism, and a detection circuit. The controlling mechanism has a plurality of resilient mechanisms, connected to the base and co-acting with the movable member, that provide at least one of a restoring force and a restoring torque to the movable member in response to the at least one of the applied force and the applied torque. The controlling mechanism further includes a restraining member, disposed within the movable member, that restrains the movable member when the movable member is in contact with the restraining member. The detection circuit co-acts with the controlling mechanism, to detect the movement of the movable member relative to the base, and provide the electronic signal.
