ABSTRACT:
A material transportation system includes one or more material transportation vehicles, each having magnetic wheels coupled to a magnetically attractive surface that can include a ceiling, a wall, a floor, and/or a transition region. The material transportation vehicles are adapted to carry material from place to place. Each material transportation vehicle has sensors and motor controls that reduce swing motion of the material transportation vehicle and the material coupled thereto. A collision avoidance and traffic control system prevents collisions between the one or more material transportation vehicles.
