Abstract
Reporters obtained the following quote from the background information supplied by the inventors:“The invention generally relates to robotic and other sortatio n systems, and relates in particular to roboticsystems having an articulated ar m with an end effector that employs vacuum pressure to engage objectsin the env ironment.“Most vacuum grippers employ vacuum pressures well below 50% of at mospheric pressure, and arereferred to herein as high vacuum. A typical source for a high vacuum gripper is a Venturi ejector, whichproduces high vacuum but l ow maximum air flow. Because of the low flow, it is essential to get a goodseal between a vacuum gripper and an object, and it is also important to minimize th e volume to beevacuated.
