Swims like a tuna, looks like a tuna

Wow, of all the animal-like robots you've reported on, Ann, this  one really takes a page from its animal muse. I could see these robot tunas combing through rough waters and countless fisherman after them for the daily catch. Amazing, in terms of design, any way.

Thanks, Beth. I just wish we had a video of this one, so we could see how close its movements are to the original.

You bring up a very good point in regards to fishermen capturing tuna. I wonder if the design team thought about the fishing scenario and has provided a mechanism to protect there robot from fisherman. As always, Ann, a very good article on robotic applications. Keep them coming!!

That's an interesting point about fishermen and this robot tuna. Unless they're fishing near downed oil tankers, it may not be a problem. (And if they are, I hope I don't eat their tuna!)

Ann, I see your point. Yeah eating the tuna would be too much iron in one's diet. LOL

mrdon, you gave me a laugh. I was thinking less about nutrients than pollution: real tuna with tanker oil all over it. Yech.

Hi Ann, I'm glad you enjoyed the comment! Who said you can't have fun with technology?

These would be invaluable in checking exactly how much irradiated water is seeping into the sea out of the pipes of the Fukushima reactor.

Cabe,

I agree. Robotic tunas will definitely be an assest in investigating hazardous water conditions and collecting environmental data from a catastrophic event like the Fukushima reactor.

Do they school

Ann, this is really amazing, and one of the more appropriate bio inspired designs you have reported on.  I was just wondering, though, if you put a bunch of them together, would they form schools?  That would be a great sight.  It might also help catch people fishing illegally.

Lou, schooling in fish is basically swarming behavior--the term swarming is taken from insects, but the collective movements and communication are the same idea in robotics, whether the model is a flock of birds, a swarm of insects or a school of fish. These robotic tuna were designed to operate individually, not in groups via swarming behavior. But that would be an interesting option.

prevention vs repair

It would be fantastic if this is used to detect small leaks (that often lead to bigger problems) in oil tankers, rigs, etc.  They could be repaired before there's a problem.  Being ablt to navigate through oily water, after a spill, is useful too.

We'll need the earthworm equivalent very soon to help with the new oil pipelines.

Nadine, I like your earthworm equivalent idea. There are robotic snakes/worms used in medicine for detecting various substances. I wonder if those, or similar technology, could be ruggedized and adapted for pipelines?

Pipelines and maybe even tight spots in mines. Definitely would have been helpful in disasters like the Chile mining incident a couple of years back.
