Two-Phase Gripper to Reorient and Grasp
Two-phase gripper. The gripper reorients and grasps an object while being picked up, The gripper Includes a parallel jaw gripper including a pair of opposed, two-phase fingers, each finger including a cavity covered by an elastic strip wherein the elastic strip includes a point contact. Closure of the jaws of the gripper on as object at a first relatively lower force results in contact with lower friction between the point contact on the elastic strip on the fingers and the object allowing the object to rotate under gravity as the gripper is raised. Thereafter, closure of the jaws of the gripper on the object at a second relatively higher force causes the elastic strip to receded into the cavity resulting in multi-point contact with higher friction between the fingers and the object to securely grasp the object. In a preferred embodiment, the cavity is a Y-shaped groove and the object is cylindrical or prismatic.
SEMICONDUCTOR CLEANER SYSTEMS AND METHODS
In an embodiment, the present invention discloses a EUV cleaner system and process for cleaning a EUV carrier. The cuv cleaner system comprises separate dirty and cleaned environments, separate cleaning chambers tor different components of the double container carrier, gripper arms tor picking and placing different components using a same robot handler, gripper arms for holding different components at different locations, horizontal spin cleaning and drying for outer container, hot water and hot air (70C) cleaning process, vertical nozzles and rasterizing megasonic nozzles for cleaning inner container with hot air nozzles for drying, separate vacuum decontamination chambers for outgassing different components, for example, one for inner and one for outer container with high vacuum (eg., <10.sup.6 Torr) with purge gas, heaters and RGA sensors inside the vacuum charnber, purge gas assembling station, and purge gas loading and unloading station
Deformable gripper arm
A refuse collection vehicle includes a refuse grabber assembly, a lift arm coupled to the refuse grabber assembly, and a hopper configured to receive refuse from the refuse container. The lift arm is operable to position the refuse grabber assembly. The refuse grabber assembly includes a first grabber arm and a second grabber arm that are configured to cooperate to engage the refuse container. The first grabber arm includes a first gripper and a first support arm coupled to the first gripper. The first gripper includes a first deformable structure configured to contact a first surface of a refuse container. The second grabber arm includes a second gripper and a second support arm coupled to the second gripper. The second gripper includes a second deformable structure configured to contact a second surface of the refuse container.
