For its size, VELOCIRoACH is easily the fastest robot in the world--it can cover 26 of its own body lengths in the span of a second. It does so by employing legs much like those of the actual cockroach that act like springs as they hit the ground 15 times per second. At any given time three legs are touching the ground giving the robot very good stability. And, like the real thing, the cardboard cockroach can skitter right over obstacles by bouncing its front end upward and pulling itself over. It can even carry four times its body weight.
