ABSTRACT:
A versatile robotic gripper is easily and quickly adjusted to grip objects of different geometrical shapes without changing parts and under complete machine control. Opposing jaws have a matrix of axially movable pins each of which is mechanically locked in any axial position. Actuation of an operating mechanism to move the jaws together to grasp an object depresses the pins and they collectively conform to the shape of the object; the jaws retain this shape upon release of the object. A plate is raised to unlock the pins which are returned by springs to a fixed coplanar position.
