Abstract

A robotic system can include or be coupled with an end effector assembly. The end effector may include multiple of suction cups configured to individually receive suction pressure (e.g., from a shared vacuum source), and a set of unidirectional valves coupled to the multiple suction cups to individually control supply or cut-off of the suction pressure to an individual suction cup of the plurality of suction cups. Each of the unidirectional valves may include a first flow path to convey the suction pressure from the source of suction pressure to the suction cup, and a second flow path extending between a suction cup to the atmosphere. The valve can be configured to switch between the first flow path and the second flow path to activate or deactivate the individual suction cup.
