I have seen a buggy built that looks a lot like this.. actually better. Seriously.
Here
ROCK RACER
Don't get me wrong that was amazing and a cool little video but check out the real little buggy
I linked to it is impressive and Its real!!
I think I will take the real thing it's awesome!!
Oh and not sure if you guys watched his other video... its like a running chicken robot.. legs mostly with a body.. but man is it smooth.. this guy is good.
