I picked this link up off of our news aggregator: Skating Robot. It is a pretty neat discussion of and some videos for a legged robot that can both walk and skate. Wheels at the tips of the legs can flip down and become feet. However, while in the rolling position there are no motors attached to the wheel. They 'free wheel'. The robot uses these like you would use skates.
