| 20080288128 | STAIR CLIMBING PLATFORM APPARATUS AND METHOD - A platform wheeled apparatus that incorporates an intelligent wheel configuration for each wheel in which each wheel can dynamically change its radius to negotiate various obstacles. The intelligent wheel has a rotational hub and support disc 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 the spokes and control components. | 11-20-2008 |
