      If you have the book "Robot Builder's Bonanza" by Gordon McComb check out
the "Damnation Alley" vehicle on pages 149 through 152.  This has a "Tri-Star"
wheel arrangement which allows a vehicle to overcome all kinds of obstacles,
including stairs.  Although the vehicle was used for a movie, the wheel
arrangement itself  is a legitimate patent held by Lockheed Aircraft for an
all-terrain vehicle.
