Snake robots can use their many internal degrees of freedom tothread through tightly packed volumes and access locations that peopleand machinery otherwise cannot. These highly articulated devices cancoordinate their internal degrees of freedom to perform a variety oflocomotive gaits that go beyond the capabilities of conventionalwheeled and legged robots. The true power of these devices is theirversatility; they can crawl, climb, swim, and scale flights of stairs.
