Snakebot

Snakes are unique creatures in that their bodies allow them to get into the cracks and crevices of the world that most other creatures cannot. With highly flexible skeletons and lacking limbs, snakes can contort their bodies in order to get into tiny holes, wrap around tree branches and slither over otherwise unmanageable rocks. These serpentine qualities are the inspiration for a new type of robotic, interplanetary probe, called a snakebot, being developed by engineers at NASA's Ames Research Center.
