Abstract
The robot has a first rail which extends in one direction and has a first slide mounted thereon, the first slide being slidable along the rail. A second rail extends away from the first rail, and has one end secured to the first slide. First and second motors are mounted in fixed positions relative to the first rail, the motors driving first and second drive belts. The first drive belt is attached to the first slide, thence routed around a first pulley at one end of the first rail, thence around a second pulley at the other end of the first rail, and thence back to the first slide. This produces movement of the first slide along the first rail. The second drive belt is routed from a third pulley at one end of the first rail, thence around a fourth pulley at the other end of the first rail, thence around a fifth pulley mounted on the first slide, thence out the second rail and around a sixth pulley mounted on the second rail, thence back towards the first rail and around a seventh pulley mounted on the first slide, and thence back to and around the third pulley. A computer controls and coordinates the first and second motors to produce movement of the first slide along a first axis …
