Abstract
A vehicle (10) for transporting a container (12) and for loading and unloading a load port (14) is disclosed. The vehicle (10) comprises a frame (16), a container holder (26) mounted to the frame (16), and front wheels (18) and rear wheels (20) mounted to the frame (16). The front wheels (18) are movable with respect to the rear wheels (20), so that the critical footprint of the vehicle is reduced during loading and unloading. The vehicle is particularly useful in personal guided systems and methods for loading and unloading wafer containers.
