Watch a robotic snake swim eerily like the real thing

Don't be shocked if you see a mechanical snake swimming around undersea equipment in the near future... it (probably) isn't there to kill you. Eelume, Kongsberg Maritime and Statoil are building a robotic snake worker that will inspect (and occasionally fix) underwater gear. Robot snakes are nothing new, but this serpent is both production-ready and almost uncanny in how it moves. Throw in thrusters, however, and it's something else -- it can quickly twist around pipes as if they were only minor obstacles.
