A Modular Snake Robot

StCredZero writes "Researchers at CMU are working on a Modular Snake Robot. A video from this site is up on YouTube. In addition to being able to traverse a wide variety of terrain, the robot can also climb poles, the inside of pipes and conduits, small grooves in walls, and probably more. It can also swim. Many robots can do one of those tasks. This one can do them all. That's quite an accomplishment. This has tremendous potential for the maintenance of fiber optic networks, pipelines, and plumbing in large buildings; and also as a spy device. (I wonder how loud it is?)"
