anyone built a Mars Rover look-alike ?

Out of curiosity, has anyone built a Mars Rover look-alike or work-alike robot ? Maybe something semi-autonomous like the real thing ? Got some
photos ? Maybe relays images to your laptop instead of JPL ?
( Now, I would be REALLY impressed if it has a rock abrasion tool on it ! )
Thanks !
