Snake Robots

"The question naturally arises, why snake robots? Biological snakes occupy a wide variety of ecological niches, ranging from arid desert to tropical jungle as well as swimming in rivers and oceans. Abandoning limbs and developing elongated spines has proved an effective survival strategy, allowing snakes to hunt underground in confined tunnels, above ground in grassy fields and up in the tree-tops, even falling in a controlled glide from one tree to the next. By attempting to build robots that emulate and perhaps match the capabilities of their biological counterparts, it is possible that we will create useful tools capable of carrying sensors, taking samples, and making physical changes in a wide variety of environments."
