I'd expect a legged lunar robot to be a tetrapod at least, or perhaps
something akin to a centaur. Two legs aren't enough to deal with
random ruggedness; it's too easy to step into a hole that you didn't
know was there before you committed your weight to that foot.


It should have six legs, so that while walking it stands stably on three
feet while moving the other three in the direction of travel. The feet
should be wheels, for the flat ground. Look up, if necessary,
ATHLETE_(robot) in Wikipedia.
