Another CNC-enabled repair robot

Turns out this isn't the first time Design News has posted a story on robotic CNC repair. Here's one from two years back:
http://www.designnews.com/document.asp?doc_id=229513
This one also began as a (relatively) mobile underwater repair station, although specifically for repairing welds on a nuclear reactor's containment vessel.

The FreeHex link we gave in the article has some detail and provides further links to yet more detail. I suggest you check them out.

I am trying to imagine what sort of repairs need precision machining, and finding it a bit of a challenge. Mostly, repairs involve either replacing a broken part or tightening something that has come loose. BUt I am sure that a robot that is able to do precision machining of some kind will find a few uses eventually.

This is a news story, not a product story or an in-depth feature article. It's also true that the MiRoR site has, regrettably, very little info available. That's why we also gave the link to the FreeHex info, which is more detailed. It's a bit early for a purchase decision. No doubt if and when this becomes ready for sale there will be lots more detail. Meanwhile, you might consider writing one of the consortium members.

I like the idea of these bots crawling around machines to do repairs. Like a building or a ship with a living organism's blood cells, repairing all the time. The best tech imitates life.

"Submarine repair" is rather vague, though, without knowing exactly what sort of repair operation it might be performing. When I read these sorts of articles, I'm usually thinking in terms of "how can we apply this to our business?" I just couldn't find anything in the article describing what it might do (cut, grind, weld, measure, etc) in a way that would allow me to extrapolate its usefulness. "Repair" is really too general for a technical magazine.

As the article clearly states, Rolls-Royce commissioned the original for use on submarine repair. The leg attachment is described in somewhat more detail at the FreeHex link we gave in the article.

Real-world applications?

I'm not at all clear on what the specific applications for such a machine would be. Currently, the main example of automated/robotic maintenance in inaccessible places are the "pigs" used to maintain pipelines. They're well-served by the current form factor.

I question the usefulness of the "legged" deviced describe because it's not at all clear how it would attach itself rigidly to the structure being repaired. If there's one requirement for machine tools that's held true for two centuries, it's that they must be very rigidly. The machine shown, with articulated legs and a gooseneck tool head is far from rigid, and I guess we're supposed to believe that the legs just magically stick to the workpiece. Given that, by definition, it will work in confined places, there isn't likely to be any convenient place for it to stand and attach itself.

The other big unanswered question relates to what it would do even when it gets to where it needs to go and somehow attaches itself. Most repair operations require additive processes such as welding cracks or flame-spraying worn shafts. I can't think of any common repair to a machine, other than cleaning, that solely involves removing material. Furthermore, within a machine, wear usually happens where two parts are in contact, such as a shaft and a journal, so the parts must be separated before they can be repaired, no matter what method is used.

If one could build a gear-repair machine that could somehow crawl down inside a gearbox, flame-spray worn gear teeth, heat treat them, grind them to the desired shape and surface finish, and remove all grinding swarf from the gearbox, that would be a very handy robot with great potential to save money in repairing gearboxes that are large, expensive, and inaccessible (e.g. wind turbines). However, every one of those steps, by itself, appears to be impossible for anything resembling the device described here, all of them must be performed for the device to be useful, and combining them all is pure fantasy at this point.

Thanks for your input Cabe. I agree, isn't the concept a cool one? Bring the small mobile repair machine to the big hulking array of things that need repairing, are mostly connected to each other, not easily movable and/or dangerous to work with.

Hexapod machining is growing in popularity. I love this concept, spot machining. This looks heavily geared towards the building of all types of vehicles. I would like to see the concept adapted for circuit building and repair. Also, sounds like a new system for graffiti, carving a "tag" on a wall.
