Carnegie Mellon University’s Biorobotics Lab shows off their new modular snake robot, Unified Snake. Watch as it climbs up a pole, performs rolls, and sidewinds.

This work considers two issues: snake robot locomotion and modular robot design. We achieve snake robot locomotion by designing gaits, which are cyclic internal motions that allow the mechanism to interact with the environment to propel itself forward. Our gaits enable snake robots to maneuver through a variety three-dimensional terrains and include swimming and climbing. The robots, themselves, are a modular chain of single degree of freedom units each powered by a low-cost, yet modified, hobby servo that we call the Super Servo. We have updated the internal electronics in the servo as well as created new mechanism designs so as to optimize efficiency and robustness.

    That is awesome…pretty amazing what sort of movement can be made with a very simple (looking) design. I would be curious to see what sort of implementations could be had for a snake-design.

    I actually saw this about a month or 2 ago in person. It was incredibly neat. I brought my 2 year old son and he was mesmerized by the way it was moving. The way it moves it in a shape of a sin wave.. just think back “Why would I ever need to learn about sin waves???”… well.. there you go.

    Anyway, nice find. The videos are great.

    Head movement can improve, if they give the head an independent movement could also roll forward

    its design is excellent,

    will have great contributions to search and rescue incorporating a camera
