  "abstract": "A zoned vacuum gripping tool comprising one tool-change interface, three suction cups, one vacuum pump, three isolation valves, three zone branches and one vent valve. When the suction cups reach the workpiece, the suction cups are evacuated by the vacuum pump. After the workpiece has reached the set-down position, the vacuum circuit is vented by the vent valve. The arrangement is a proposed configuration composed from a typed library of mechanism blocks derived from published patents; it has not been constructed.",
