It may be just circuits and metal, but this robotic snake from Carnegie Mellon University's Biorobotics Lab will give you flashbacks to the hydrobots from Terminator Salvation. Behold the robot that could someday be used for surgeries and search-and-rescue.

Carnegie Mellon hopes that these serpentine robots will someday be adapted for crisis relief and have medical applications — the snakebot's wriggling design allows it to navigate small areas that conventional robots may be vexed by. For example, the snakebot could be adapt to find earthquake victims:

Snake robots have many more degrees of freedom than conventional robots and rescue machinery, while at the same time have a small cross-sectional area. These many degrees of freedom enable snake robots to thread through tightly packed volumes reaching locations otherwise inaccessible to conventional robots and people, while at the same time, not disturbing the surrounding areas. This is critical in search and rescue operations where large pieces of debris become fragile make-shift support structures.
