  "abstract": "A suction-cup vacuum gripping tool comprising one tool-change interface, one suction cup, one plant vacuum connection, one isolation valve, one pressure sensor, one contact detector and one vent valve. When the suction cup reaches the workpiece, the suction cup is evacuated by the plant vacuum connection. 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.",
