Abstract:
1. An apparatus for handling a disk-like member, comprising: a robot for carrying out at least an angular motion in a defined plane of motion; a wrist member that can be driven by said robot and forms a rotating mechanism for said disk-like member; an end-effector that can be driven by said wrist member, for holding and rotating said disk-like member about an axis perpendicular to a flat surface of said disk-like member, so that a surface of said disk-like member to be inspected can be offered in a desired inclination, wherein said rotating mechanism includes a pair of wheels having an axis of rotation in said flat surface of said disk-like member; wherein said angular motion of said robot and said rotating motion of said end-effector are combined to achieve said desired inclination of said surface, wherein said end-effector includes a body having an edge-gripping mechanism within that carries the disk-like member, and wherein said body having said edge gripping mechanism is arranged in a space between said pair of wheels and is fixedly connected to said pair of wheels.
