ABSTRACT:
An apparatus for gripping objects comprising a first jaw having a first support member and a first support plate that is slidingly attached to the support member with respect to a first direction or motion. The apparatus is also comprised of a second jaw that has a second support member and a second surface plate attached to the second surface member. Additionally, the apparatus is comprised of a structure holding the first jaw and the second jaw such that the first jaw and the second jaw can move in a second direction toward or away from each other to grip or release the object, respectively. In a preferred embodiment, the second surface plate is fixedly attached to the second support member and the first direction is perpendicular to the second direction. The sliding action of the first support plate acts to reduce the effective frictional force between the object and jaws to facilitate stable grasping.
