An end-of-arm-tool attachment deploys gripper arms to help stabilize picked items. The arms rotate around the lower body of the tool and, depending on the size of the item, will either support the item from below or help reduce swinging by applying pressure to the sides/top. When not in use, the arms are stowed on the upper body of the tool to minimize potential for collision and to provide a smaller profile for maneuverability.

Concentric suction cup array for end-of-arm tool

An end of arm tool includes concentric rings of suction cup assemblies. Each suction cup assembly includes a tube for supplying vacuum and a distal suction cup. The suction cup assembly can be longitudinally moveable (that is, in a retraction direction) upon engaging an item. Each ring has a vacuum control. Each ring can have its own action or compliance.

An end-of-arm tool includes concentric rings of suction cups. The pneumatic actuators control the extension of suction cups, and are actuated in rings. Each suction cup is longitudinally retractable in response to a force applied to an item and has a compliant suction cup. Each ring has a vacuum control. Each ring can have its own compliance.
