This robot has six legs, and I"m including a simple extra-terrestrial landscape. It"s set up using inverse kinematics, and is incredibly easy to animate. After you download it, you can mess with the "smooth" modifier to change the shape of the robot. Tons of shapes can be made just by adjusting the smooth factor. The one with the blue background is one such example. Everything you see in the renders comes with the product
PostScript: It"s already animated, I included very convincing walk/run cycles, and a "fold up--unfold" sequence.
