Abstract
A gripper assembly is provided. The gripper assembly comprises a pair of moving assemblies. In an exemplary embodiment, the moving assemblies comprise a pair of grippers coupled to a pair of gripper fingers that have end effectors adapted to contact a wafer. A magnet is placed in each of the moving assemblies so that the attractive force between the magnets moves a portion of the moving assemblies toward each other.
