  "abstract": "A foam-pad vacuum gripping tool comprising one tool-change interface, three foam pads, one ejector, one isolation valve, one manifold, one contact detector and one vent valve. When the foam pads reach the workpiece, the foam pads are evacuated by the ejector. 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.",
