Abstract
Systems and methods are provided for utilizing enhanced vacuum gripping techniques. One embodiment is a method that includes locating an array of valves for an end effector, selectively switching valves within the array between open states and closed states based on a shape of a work piece that the end effector will transport, selectively applying vacuum through a plurality of valves in a shape that corresponds with the shape of the work piece, disposing the end effector at the work piece while the vacuum is applied to grip the work piece, and picking up the work piece by moving the end effector while the vacuum is applied.
