  "abstract": "A zoned vacuum gripping tool comprising one tool-change interface, four bellows cups, one ejector, four isolation valves, four zone branches, four pressure sensors and one vent valve. When the bellows cups reach the workpiece, the bellows cups are evacuated by the ejector. 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.",
