Rotating end of arm tool including asymmetrical independently controllable suction zones

A system, comprising:

• a robotic manipulator;
• and
• an end of arm tool to detachably couple with a distal end of the robotic manipulator, the end of arm tool comprising:
• a stator rotary union comprising a first pneumatic outlet and an electrical pathway;
• a rotor rotary union rotationally connected to the stator rotary union and comprising a plurality of second pneumatic outlets, individual second pneumatic outlets of the plurality of second pneumatic outlets being independently openable and closeable;
• an electro-pneumatic rotational joint defined by the stator rotary union and the rotor rotary union, the electro-pneumatic rotational joint enabling the rotor rotary union to rotate at least 300 degrees about a tool axis with respect to the stator rotary union, defining the electrical pathway, and defining a pneumatic pathway between the first pneumatic outlet and the plurality of second pneumatic outlets;
• and
• a suction manifold connected to the rotor rotary union, the suction manifold comprising:
• a bottom;
• a lid comprising a plurality of third pneumatic outlets in pneumatic communication with the plurality of second pneumatic outlets;
• a perimeter wall extending between the lid and the bottom so as to define an interior chamber having an interior volume;
• at least one interior wall that divides the interior chamber into a plurality of asymmetrical sub-chambers, each asymmetrical sub-chamber defining a distinct interior sub-volume and an independent pneumatic pathway with one of the third pneumatic outlets of the plurality of third pneumatic outlets;
• a first set of suction devices connected to the bottom and in pneumatic communication with a first asymmetrical sub-chamber of the plurality of asymmetrical sub-chambers to define a first suction zone;
• and
• a second set of suction devices connected to the bottom and in pneumatic communication with a second asymmetrical sub-chamber of the plurality of asymmetrical sub-chambers to define a second suction zone, wherein the first suction zone and the second suction zone are independently operable.
