Patent ID: 7264436

Claim:
A robot-guidance assembly for carrying out precision motions of a disklike object, comprising a robot including at least one robot arm having a first free end and a second driving end so that said first end of said robot arm is adapted to be moved in at least one plane of motion; an end-effector for holding and transferring said disklike object, said end-effector being attached to said first end of said robot arm; a precision guiding apparatus being part of a production or inspection apparatus and adapted to and provided for precisely guiding said end-effector in said at least one plane of motion and extending parallelly to said at least one plane of motion, said precision guiding apparatus including a stationary guiding device and a movable guiding device which is guided on said stationary guiding device; and a coupling mechanism for removable mounting one of (a) said first end on said robot arm, or (b) said end-effector, to said precision guiding apparatus so that said robot is prepared to drive said movable guiding device when said coupling mechanism is coupled.
