  • Stair climbing platform apparatus and method
    Patent number: 7806208
    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.
    Type: Grant
    Filed: May 30, 2008
    Date of Patent: October 5, 2010
    Assignee: Gamma Two, Inc.
    Inventors: Louise F. Gunderson, Christian Brown, James P. Gunderson
  • STAIR CLIMBING PLATFORM APPARATUS AND METHOD
    Publication number: 20080288128
    Abstract: 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.
