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?)"

a little weird

[OrochimaruVoldemort]

but useful. the telcos would sure like one of those. the us govt. would also see an interest

Re:

[Brian Gordon]

Uh they're far from actually making delicate repairs on fiber.. but I was very wowed by it snaking around on that horizonal pole. That must be some crazy programming for it be able to keep balance and not fall off.

Re:

[Bozzio]

Wouldn't it depend on how it's built?
If it's got sensors that tell it where its point of contact are, then it should be pretty simple to keep at least two loops around the horizontal pole.

Maybe I'm completely off, but that's how I'd do it.

Re:

[phillips321]

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.

Does anyone else smell a "Snakes on a Plane" sequel?

Sadly, it's been done [imdb.com]....

Re:

That's not a sequel, it's the typical The asylum copycat version of a popular film. Check their filmography [imdb.com] for other jewels like The DaVinci Treasure (The DaVinci Code), I Am Omega (I Am Legend), Transmorphers (Transformers) or 100 Million BC (10,000 BC).

Nah, I can think of more entertaining stuff

[Moraelin]

Nah, I can think of far more entertaining stuff. Like programming one to give your least favourite luser/coworker/boss/etc a colonoscopy.

Re:

[electricbern]

Yes, but the snakes would have to be shutdown for takeoffs and landings as not to interfere with the plane's equipment (???).

Re:

Imagine a beowulf cluster of these!

Re:

[An ominous Cow art]

This would be known as a "Jormungand Cluster".

Unfortunately

[d3ac0n]

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.

Evangelion

[StCredZero]

The prototype Evangelion [google.com] were tethered, but they did a whole lot!

Re:

[EmperorKagato]

Yes and the advancements in machine efficiency.

Re:

[wodon]

It seems that they can work wireless.
The swimming motion does not use the tether.(5th section down in the linky below)

Re:

[v1]

Tethered is not necessarily a big limitation. Imagine you need to inspect a 200ft long pipe. Send it down (or UP!) the pipe, the tether is not a big deal. Unteathered is only important if you have to go a long distance, or have to go far down something you have to roll over. (did you notice the teather start to wind up in a few of them?)

Re:

[ivanjager]

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 wit

Great Surveillance Possibilities

[Russell2566]

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...

Re:

[PolarBearFire]

They already have remote control roaches. How about remote control snakes? They are much more mobile and flexible than anything we can make out of metal and plastics. Solves battery problems, noise issues, controls vermin pop, etc.

Re:

[calebt3]

Better for survoliance purposes, maybe. But try replacing a real snake's mouth with some sort of tool or sending it into hazardous environments. Also, I haven't ever seen a snake climb a pole. So even if the authorities don't use this robot, we should still pursue it's development.

Re:

[mabhatter654]

They're called tree snakes! Most snakes in the north are too small, but in the jungle, many live in trees (their kind of like poles)

planetary exploration?

[CarpetShark]

From the description of what it can do, it sounds like the answer to a lot of NASA's terrain negotiation problems. Anyone have an idea if this (perhaps on a larger scale) would suit them?

Cool

[PolarBearFire]

Very cool, but what would be even cooler is if it had sensors and an electronic brain that could coordinate all its movements. That would be a greater breakthrough than just the robotic component.

Impressive

[Degreeless]

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.

If she's your wife and she hasn't introduced you to her "toys" yet, you're missing out on half the fun :P

Of course we are all speaking in theory because no one in slashdot is married, the only women we see are images on our computers and our mothers when we ascend from the basement (MOM!!! MORE HOT POCKETS!!!), and of course the wife and two kids I have in the picture here in my office are fake... they came with the frame :)

Robot Snakes

[verbalcontract]

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.

Oh, so real snakes aren't scary enough? I have to worry about robot snakes too?

Imagine one of these quietly sneaking up on you at night and crawling on you while you sleep, turning its 'face' towards you and suddenly calls "BOOOO!", then quickly escaping. The coroner will have a hard time to finding out wtf happened.

Old hat

[Lars Clausen]

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.

-Lars

I think I saw that one

[blueZ3]

When the Decepticons were near it would transform into a giant robot! Who knew that PARC was responsible for the autobots?

Re:Old hat

[PlatyPaul]

You're referring to Polybot [parc.com], which has Generation I [parc.com] 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.

Even older hat

[jmichaelg]

John Calhoun of Glider [mac.com] fame built a snake robot back in the mid 90's. He showed it to me during the summer of 95. It wasn't water proof, couldn't climb cracks and tubes like this one can but otoh, it was untethered and could amble around his apartment.

The thing that impressed me the most was he built it with hand tools in his apartment as he didn't have access to a machine shop.

Other YouTube videos

[honestmonkey]

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?

promising

[darkob]

This is definetelly very promissing technology. I can easily imagine letting one of those (tethered, why now) devices into sewer (or even into toilet) two, three blocks away from the target.

Robot regulation and EULA

[Benjamin_Wright]

Picture the future. As StCredZero suggests, the unleashing of robots into society will raise privacy and other legal questions. The questions can in part be answered with devices that resemble the end-user license agreements we see on software today. Robot "terms of service" will be one tool for regulating robot bad behavior or unwanted spying. http://hack-igations.blogspot.com/2008/01/robot-surveillance-contracts.html [blogspot.com]

[souplogic]

It's a lot of time and money put into chaining servos together, something like this could likely be put together using parts from lynxmotion.

What would be impressive is to get onboard power, communication and sensors onto this body without hampering its physical abilities, then give it some sort of capability for autonomy. This thing presents a sensor integration nightmare, and solving that would be useful indeed.

Re:

Bigger? OK. Louder? Probably. Cooler looking is subjective, for sure. But more destructive? I'd say they're both tied for zero in that category. That "battle worm" thing just flailed helplessly as a little car bashed it to death.

For cooler looking my money's on the Japanese snake robot at the end of this video [youtube.com] -- its' much smoother than the one in the OP.

Re:

[trongey]

But more destructive? I'd say they're both tied for zero in that category.

Aww, come on. Give the guy the credit he's due. As I recall, the snake did manage to flop over onto it's first opponent and win that match.

Solid Snake

[Aegis Runestone]

Okay, that's really cool, but does it eat apples? :P

Anyway, I watched the snake hanging on a horizontal pipe in the upper area of a room. Maybe they could be used as mobile security cameras that could follow a susipcious person or possibly, if it can, communicate to other snakes about the problem.

Hmmm... this brings a whole new meaning to name: "Solid Snake."
