A pole balancing cart on an unmodelled terrain

A pole balancing cart comprises a wheeled or track-guided vehicle which can move under its own power in the fore-aft direction, and a pole pivoted at its lower end which can swing smoothly in the fore-aft plane like an inverted pendulum. The cart is able to balance the pole in a near upright position while it moves across an unmodelled terrain through sensing the inclination of the surfaces and noise compensation. The cart with an inverted pendulum is a classical example in the control of unstable systems. This paper describes the mechanical, electrical, and electronics design of such a pole balancing cart.
