This article on New Scientist about a nifty new type or robot wheel which can roll around by itself. It uses heat to shrink and expand the spokes, thus changing the center of gravity and allowing it to roll up inclines of up to 20 degress and jump up to 8cm.
How long before these are sold on ThinkGeek?
