Rotating end of arm tool including asymmetrical independently controllable suction zones

Examples described herein are directed to methods, computer-readable media, and systems for controlling an end of arm tool with one or more suction zones to pick up an item. Sensor data regarding the item is obtained. The sensor data is used to determine which of the one or more suction zones should be used to pick up the item. A rotational orientation is also determined that orients the determined suction zone(s) with the item. The end of arm tool is then instructed to create a suction force at the one or more suction zones and to pick up the item using the suction force.
