ABSTRACT:
A transporting system for a robot comprises a self-propelled wheeled platform which travels along a pair of tracks which establish a path between a series of spaced work stations. Accurate positioning of the platform at the work stations is achieved by a toggle-operated platform-mounted mechanism which lifts the platform above the track, using four precisely positioned locator blocks fixed to the tracks at each work station. These blocks provide a reaction and reference surface for the lifting mechanism and have formations which cooperate with formations on the carriage to cam the carriage into the desired longitudinal and transverse position as the carriage is lifted. The lifting mechanism also functions to fixedly clamp the carriage to the locator blocks once the final position has been achieved. Alternative embodiments permit precise elevational and lateral positioning at predetermined elongated positions along the track, while loosely gripping the elongated locator blocks, thereby permitting the robot to perform operations as it moves along the track, while still being precisely positioned and stabilized against overturning tendencies.
