Abstract

A compliant underactuated grasper includes a palm base and two fingers. Each of the fingers comprises: a proximal phalanx; a distal phalanx; a compliant flexure joint connecting the distal phalanx to the proximal phalanx; and a pin joint connecting the proximal phalanx to the palm base, the pin joint constraining angular movement of the proximal phalanx relative to the palm base to rotation about a pin pivot axis. The grasper further includes at least one actuator to move the fingers. The grasper has fewer actuators than degrees of freedom.
