Built by robotics students at Carnegie Mellon, Uncle Sam the Snakebot is simultaneously horribly awesome, and awesomely creepy.
Uncle Sam is programmed with a variety of different "gaits", or types of movement patterns, which are based on the real-life behavior of real-life snakes. The goal is to create a modular—and, thus, relatively simple to produce and scale—robot that can get to and through places where people, and less-willies-inducing robots, can't maneuver.
