 Cheers,

Thomas

Can't go wrong with the classics, I suppose.

But don't give up! Originality is usually worth the trouble if you achieve it. I'll be looking foreward to your future robots. :) 

As an extra hint, there are a billion robots out there with ~3~ wheels.

As far as the 3 leg thing...It would be incredibly hard to get it to move in a stable matter. Even 4 legged robots have some trouble walking.

 For stable movement, why not try 6 legs. (Like an ants!)

 However, if you have your mind set on an innovative tripedal robot, try putting some weight in the middle leg, and let it do a "Sapian/caveman walk"

Just pretend the gorillas actual legs is one big, flat leg.

Yeah, after a long look at the possiblities a 3 legged walker is not looking too posible at the moment. I'm just going to have to continue building my 1:1 replica "wall-e" instead :)

Hi,

I always thought this was a wicked imaginative solution to the 3 leg mobility problem.

It falls and rotates its whole body around 2 legs.  The sensor platform would be flipping upside down and right side up - but that could be a good thing (possibly) for scanners and such.
