when you pedal a ten speed, as long as the wheel is going slower than the pedals, the pedals stay engaged. If you go down a steep hill, and dont pedal faster, then the pedals are just spinning, and the back wheel is going faster, right?

Only drawback, you cant go backwards, unless you add a reverse gear.
If I'm not mistaken the majic behind that is called a one-way bearing. Interesting how you described it being applied to a robot. Instead of the one-way bearing, what about something like manual locking hubs on an old 4x4 truck/suv?
