  "abstract": "A zoned vacuum gripping tool comprising one mounting flange, three bellows cups, one vacuum pump, one manifold, three zone branches, three pressure sensors, one contact detector and one vent valve. When the bellows cups reach the workpiece, the bellows 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.",
