  "abstract": "A foam-pad vacuum gripping tool comprising one tool-change interface, one foam pad, one vacuum pump, one contact detector and one blow-off valve. When the foam pad reaches the workpiece, the foam pad is evacuated by the vacuum pump. After the workpiece has reached the set-down position, the workpiece is blown off by the blow-off valve. The arrangement is a proposed configuration composed from a typed library of mechanism blocks derived from published patents; it has not been constructed.",
