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.

An adaptive gripping device for industrial robots and fixturing parts comprising: two substantially identical opposing jaw assemblies both having a matrix of axially movable gripper pins and means for biasing said pins to a fixed position; an operating mechanism on which said jaw assemblies are mounted to have opposing linear relative motion to grasp and release an object, and means for activating said operating mechanism to slide said jaw assemblies together causing individual pins to contact the object and be depressed and collectively conform to the shape of the object; each jaw assembly including pin locking means comprised of two locking mechanisms for each pin operating in opposite directions that mechanically lock the pin in any position within its range of motion when an axial force is applied to the pin, whereby said jaw assemblies retain the object shape after release of said object, and pin unlocking means actuated by power means for unlocking all of said pins which are returned by said biasing means to said fixed position.
