  "abstract": "A foam-pad vacuum gripping tool comprising one tool-change interface, four foam pads, one plant vacuum connection, one manifold, one pressure sensor and one vent 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 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.",
