We saw millipede when we were walking along the Lake Ashi. We were so impressed by its legs synchronizing perfectly, and making beautiful waves. We were talking about a robot of millipedes. Probably, the program for moving hundreds of legs perfectly will be very complicated, and the robot will move very very slowly if we are allowed to pack only a small computer in it. So again, life is amazing. This small millipede can run without thinking using its small "brain", which probably has very complicated neuron networks.
