Concentric suction cup array for end-of-arm tool

Abstract:

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.
