  "abstract": "A foam-pad vacuum gripping tool comprising one tool-change interface, two foam pads, one plant vacuum connection, one isolation valve, one manifold, one pressure sensor, one contact detector and one blow-off valve. When the foam pads reach the workpiece, the foam pads are evacuated by the plant vacuum connection. 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.",
