ABSTRACT:
A robot system includes a support assembly and a robot arm. The robot arm includes a platform and a carriage movable back and forth along the platform. A shuttle is movable back and forth along the carriage. A first belt and pulley system is provided for moving the carriage back and forth along the platform and a second belt and pulley system is provided for moving the shuttle back and forth along the carriage. Each belt and pulley system includes a belt and a first pulley. The diameter of the pulley on the first belt and pulley system is one half the diameter of the pulley on the second belt and pulley system. The first pulley on the first belt and pulley system and the first pulley on the second belt and pulley system are fixedly coupled relative to each other so that rotational movement of one of the first pulleys will cause the same amount of rotational movement of the other one of said first pulleys. Consequently, the amount of movement of the carriage relative to the platform will be one half that of the amount of movement of shuttle relative to the carriage and the resulting movement of the shuttle relative to the platform will be the sum of the movement of the carriage relative to the platform and the shuttle relative to the carriage. The belt on the second belt and pulley system is driven by a motor.
