Much has been said about how Japan is better prepared for earthquakes than any other country, and some of this prep involves the robots they have developed to help in rescue situations. This self propelled snakebot is designed to burrow deep into collapsed buildings, showing rescuers anyone who might be trapped inside.
Developed by leading Japanese rescue-bot researcher Satoshi Tadokoro, the Snakebot has motorized nylon bristles that propel it along like a snake, wriggling through the tightest cracks. A pair of joints near the head allow it to make tight turns, while a camera and light send back information about what's buried.
Hopefully, the Snakebot is being used right now to locate buried victims.
