Satoshi Tadokoro, one of Japan's leading rescue-bot researchers, is responsible for this snakebot, aimed more at the "search" part of search and rescue. The 26-foot-long, inch-thin snake actually propels itself with motor-powered nylon bristles. It may not move fast--around two inches per second--but it's capable of turning sharp corners, climbing 20-degree inclines, and squeezing through tiny gaps, and with its camera "eyes," it's capable of sending back images that let rescuers know the situation inside a disaster zone. It's been successfully tested in both control and real-life situations, helping a rescue team with a parking lot collapse in Florida.
