Abstract
An end effector for a robot having an array of suction cups includes an air control valve connected to each suction cup. Each valve can be individually operated so that specific zones of suction cups may be activated while others are dormant. The dormant suction cups are closed to the sub-atmospheric pressure, so that leakage of air through unused suction cups is avoided, while only the suction cups of the selected zone perform the picking of the work products. This allows the end effector to provide accurate and constant sub-atmospheric pressure to the work products during the picking process.
