ABSTRACT:
A method for controlling movement of an intelligent wheel over a discontinuity in a travel surface. The intelligent wheel has a rotational hub and support disc portion that carries a series of arcuately spaced extendable, weight bearing radial spoke mechanisms that can be controllably extended and retracted in response to the anticipated terrain surface over which the wheel is to travel. The hub of the intelligent wheel carries a microcontroller for a set of obstacle proximity sensors, force and position sensors and an appropriate electrical power supply for operation of spokes and control components.
