Abstract
A voluntary close mechanical grasping device suitable for use in robotics or as a prehensor for body-power prosthetic equipment provides an energy efficient two stage process for sizing and gripping an object and a holding assist capability for assisting a wearer in maintaining his or her grip on the object. During the first stage, the device sizes an object but does not apply a force against the object sufficient to grasp the object securely. During the second stage, the device exerts a force against the object sufficient to grasp the object securely. After the object has been grasped, the device provides a mechanical holding assist capability to help hold the object securely while the input energy supplied by the wearer is reduced.
