When the world's first amphibious robotic snake became declassified, Discovery aired freaky video of it in 2010. The robosnake demonstrated impressive speed, both in hallways and the pool. It also sported a brightly lit "eye" containing a camera. Instead of preying on unsuspecting civilians, the robot was created for applications such as locating victims following an earthquake and performing minimally invasive surgery. On a more practical level, technologists at the Fortune Institute of Technology in Taiwan designed a robotic snake called BioCleaner2 that contains special bacteria to clean toxic metals from water as it moves.
