  "abstract": "A zoned vacuum gripping tool comprising one tool-change interface, one foam pad, one ejector, one manifold, three zone branches, one contact detector and one vent valve. When the foam pad reaches the workpiece, the foam pad is 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.",
