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?)"

      The problem we are at is that any robots we make have crap movement and physical structure but we can 100% control their brain.
      On the alternative, live animals have the movement we desire sadly we have yet to 100% control their brains.

    They are still all Tethered units, which limits their functionality. Of course, they are still in the development stage, so a tethered unit is to be expected.

    It will be interesting to see if they can progress beyond tethered to wireless, and finally to fully autonomous units. I would imagine that they will need to get a bit bigger to accommodate the extra electronics needed.

    Still, a very cool and potentially VERY useful technology.

      No, they are not all tethered any more. They've had an untethered one for about a year now. I could go down and ask them how long exactly if anyone's really interested.

      They are pretty lound however, especially the untethered one I saw, as it needed a high speed fan on it to keep stuff cool. I don't remember exactly why they needed the fan, but I think it might have been because they didn't want huge heatsinks on the voltage regulators. The other source of noise of course is the sound of dozens of servos with cheap gearboxes. Each joint is controlled by a separate servo.

      Sorry, I don't really know much about the current status, as I haven't been keeping up much after I leaving that lab. I still work at CMU, so I still see them now and then.

    I bet this would be an amazing tool for Police, Swat and the likes. I bet our boys over seas could find some uses for it as well to sneak into places undetected.

    Too bad it's probably really loud on hard surfaces and requires a massive cable bundle...

  6. Impressive by Degreeless · · Score: 3, Insightful

    It is an impressive feat though there ae issues of range, woth it being tethered it it's control/power, and also its application for maintenance may be limited to identifying faults depending upon whether suitable tools could be made withoput hampering the movement of the snake.

    Issues aside it also looks very cool, if a little creepy when it's climbing uyp that guy's leg.

  11. Old hat by Lars+Clausen · · Score: 4, Interesting

    The ability to climb poles (and legs) is cute, but apart from that, Xerox PARC had a modular robot in 2000 that could not only be a snake, but could reconfigure itself into a ball or a spider to go faster or to traverse difficult terrain. It was extremely nifty, but like so much else from Xerox PARC, they never capitalized much on it.

      You're referring to Polybot, which has Generation I listed at 1997. Polybot is a bit more flexible (har har) due to the fact that each module is entirely self-sufficient (aside from power, which they can channel from module to module as needed), although I haven't seen a demo of it handling water....

      "Already done" notwithstanding, it's nice to see a robot succeed so well in such varied scenarios.

    If you check the video out, it looks cool. Youtube also points out other robot snake videos. It looks like the Japanese already have several types of things like this, they are wireless and apparently have on-board batteries, and seem to do most if not all of what this one does. So, is this really a big advance or just a bad copy-cat of a Japanese version?
