space_donkey writes: Snake-like robots might make your skin crawl, but plenty of robotics researchers believe they could be idea for rescuing people buried beneath rubble, or perform military reconnaissance. Until now, however, no-one has developed a way to control them effectively. Researchers in Greece have now developed 'snake-bots' that can explore unknown areas on their own. Infrared sensors, which monitor the distance to the nearest wall or object, are linked directly to the robots control mechanism. This keeps them from bumping into stuff and helps them navigate along passageways and around corners.
