That this is great! I would take one ha ha....I do research on underground utility inpection, replacement, and rehabilitation....that little robot could have so many applications. In our research center, we actually have something that is very similar to that (except it is about 20' long and 2' diameter) that goes inside larger pipe systems and repairs damaged pipe joints....cool stuff.
That's freaking amazing 0__0 It moves just like a real snake too! (I <3 robots ^__^) I remember a while ago reading an article about a guy trying to make a lobster-shaped robot that could walk around under water but he was having problems with the dexterity or something along those lines....wish I still had the article.
