Same principle it only has six moving parts, six motors, but it has springy, tuned legs. It moves in the gait of the insect.

We couldn't believe that it could do this. It said to us that if you could build a robot with very simple, springy legs, you could make it as maneuverable as any that's ever been built.

The animals, when you look at them running, appear to be self stabilizing like this, using basically springy legs. That is, the legs can do computations on their own the control algorithms, in a sense, are embedded in the form of the animal itself.
