<p>A multi-axis robot for high-speed applications comprises a first and a second guide rail (12, 14) arranged substantially parallel to each other for defining a first axis of motion. A crossbar (16) having a first end (18) and a second end (20) is moveably supported on the guide rails (12, 14). A carriage (22) is moveably coupled to the crossbar (16) for moving along a second axis of motion. A first drive system having first and second drives and a first belt (32) running along a first H-shaped belt path provides for a movement of carriage (22) along the first and second axis of motion. Second and third belts (34, 36) extend at least partially along the crossbar (16) and the guide rails (12, 14). According to one aspect of the invention, the second and third belts (34, 36) run along different second and third belt paths, with one of the second and third belts (34, 36) entering the crossbar (16) 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 (16) with a left-hand turn and leaving the crossbar with a right-hand turn.
