Abstract

A multi-stage telescoping tube structure and a robot including a multi-stage telescoping tube structure. The multi-stage telescoping tube structure includes an outer tube, an intermediate tube, and an inner tube. The intermediate tube is slidably received in the outer tube, and the inner tube is slidably received in the intermediate tube. It further includes a multi-stage screw for arrangement translating rotary motion into linear movement of the tubes, and a drive means coupled to the screw arrangement. The robot further includes a support bracket, rotatably supporting the multi-stage telescoping tube structure, and an electric motor for rotating the arrangement. The structure further includes rail guides engagable with complimentary horizontally extending rails for horizontal movement of the robot.
