Here's a quote from Snow Crash about the "Smartwheels", which are quite similar to the TWEELs, but with lazers and hyrdrolics, and some kind of embeded computer system:
"Each one consists of a hub with many stout spokes. Each spoke telescopes in five sections. On the end is a squat foot, rubber tread on the bottom, swiveling on a ball joint. As the wheels roll, the feet plant themselves one at a time, almost glomming into one continuous tire. If you surf over a bump, the spokes retract to pass over it. If you surf over a chuckhole, the robo-prongs plumb its asphalty depths."
These new tires are also being used on the new iBot mobility device and Segway's Concept Centaur.

"Elvis the Robo-Cat is a housecat who lost the use of his rear legs in a traffic accident. His owner, an amateur roboticist, has built him a motorized platform that Elvis controls by means of his front paws in order to move around the house."

It also comes with an unmanned pathfinder which travels on a GPS controlled route ahead of the main unit. The pathfinder is secured by a 30m umbilical cord and uses ground-penetrating radar to assess risk."
Oh I have no excuse to actually own one of these, but I want one so. Reminds me of the newest Batmobile.
