  "abstract": "An end effector for vacuum end-of-arm tooling with compliant bellows cups is described. The tool comprises a tool-change interface (10), a bellows cup (12), a vacuum pump (14), a isolation valve (16), a vent valve (18). The arrangement addresses gripping workpieces that are not at the same height, where a rigid cup that reaches the workpiece first takes the whole load while its neighbours are still in the air. The description covers how the folds take up the difference, how many folds are used, and what that does to the seal at the face. Every connection is stated with the medium it carries, and the operating sequence is given as conditions on named operations.",
