Abstract:
1. A multi-axis robot for high-speed applications comprising a first and a second guide rail arranged substantially parallel to each other for defining a first axis of motion, a crossbar having a first end moveably supported on the first guide rail and a second end moveably supported on the second guide rail, a carriage moveably coupled to the crossbar for moving along a second axis of motion extending from the first end to the second end, a first drive system having first and second drives and a first belt running along a first H-shaped belt path for moving the crossbar and the carriage along the first and second axis of motion, and second and third belts extending at least partially along the crossbar and the guide rails, wherein the second and third belts run along different second and third belt paths, with one of the second and third belts entering the crossbar with a right-hand turn and leaving the crossbar with a left-hand turn, and the other one of the second and third belts entering the crossbar with a left-hand turn and leaving the crossbar with a right-hand turn.
