You know, a roaches brain is smaller than one of the dots on this percent sign % and it can control six legs at such high speed that it can out run most humans, while avoiding obstacles, adjusting to varying terrian and even switching briefly to flight if needed. What we need to do is make a chip with a roach brain in it that adapts it to control a robot. Or better yet, the mechanical aspects of a roach are pretty impressive too, why don't they do like in The Fifth Element, and make a chip controlled roach?
