A system to automate distribution of materials and tooling to production machines, where a very simple cross-section track, such as a circle or an X, is anchored to the equipment and to load/unload stations for materials and tooling, and where simple one or two wheeled robotic cars, where the wheels need not be mounted with yaw pivots to the cars, transport the materials or tooling. A control system keeps controls the motor or motors that drive one or two wheels to minimize pitch of the cars as they move along the track.
