Autonomous RoboFish at the London Aquarium 136

Posted by Zonk on Friday October 07, 2005 @09:38PM from the i-want-a-robolemur dept.

mikael writes "The London Aquarium currently has an exhibit based on autonomous robotic fish. Each fish is 50 cm long, 15 cm high, and 12cm wide with a maximum swim speed of 50cm/second with battery life lasting up to 5 hours at half speed. The BBC has more details (with video). Many more videos are available at the Robotics Video Gallery." From the article: "We have embedded sensors on board - so, unlike the previous fishes that have remote controls, these are fully autonomous and artificial-intelligence based ... This one is more life-like - it mimics normal swimming and sharp turning ... People get confused and think it's a real fish."

    The problem with that is that you'd have to extract the energy-bearing chemicals from the water (water is a chemical too of course) and that would most likely take more energy than it would yield.

      For the same reason you can't just hook the positive side of your car's battery up and expect it to work. Voltage is really a difference in potential between two points, and the water would just have a distributed potential that'd be hard to take advantage of for charging purposes.

Before anyone complains about why they make robotics fishes instead of say, a robotic trash picker or something more useful, robotics have been useful in helping us understand biology. While most of us tend to look at robots as tools to serve some purpose of ours, some scientists see robots as models. They formulate a theory and build a robotic model to tend if that theory works. Why not a simulation? Because in the paraphrased words of someone I can't remember, "When you build a robot, you get the rest of the world for free."
One very interesting example of this is when they made a robotic pike or some species of fish that propels through water in a more efficient way than we previously thought was possible. Someone came up with a theory that its movements generate eddies that help propel it along more efficiently. So, they built a robotic model to test this theory and it worked. It did swim like a pike. Does that mean that really is how pikes swim? Not necessarily but it does give some credibility to the theory.
In any case, building robotic models of lifeforms isn't as pointless as it may seem. It's not always just for entertainment.

  On one hand, I agree with you: an aquaruium does seem like an odd place to keep robots.
  
  But then again, few other museums/etc. are going to have the facilities to display robot fish swimming around with real ones. I know that the science and tech museum in Ottawa certainly doesn't have any big tanks lying around, let alone the staff required to clean tanks/feed real fish/do other such tasks. An aquarium already has all of those things and more.
  
  Besides, this is less weird than the Vancouver aquarium having

That Grant Naylor guy(s) can really predict the future.

But seriously, I sometimes wonder if humans will eventually lose some major macrofauna species and replace them with robots to console the loss (as seen in Blade Runner). For most species, I don't see this being insurmountable in the near future, especially since we have lots of film footage of the more popular species. We have faux furs in the fashion industry. The film industry makes fake animals all the time. We would easily be able to program behavi

  We would easily be able to program behaviors that account for 95% of the "real" species behavior, but it would be that last 5% that would be hard to replicate perfectly.
  That's easy...just program them to go where they can't be seen 5% of the time.

Fish with no identifiable markings? or perhaps they've scrubbed off their VINs?

Another thing that comes to mind is... now all they need to do is invent little tiny floating photocells attached to battery packs (with power terminals on them somehow) and introduce 'robo-plankton' to recharge the fish!

So what happens if they put these robofish in with real fish? Are they able to school with them and follow the pack around? If they could do that this could provide a neat way to track schools of fish in the ocean without having to attach sensors to real fish. Add some sensors for determining when it gets out of water and you might have a way to catch people engaged in illegal fishing.

  There have been many studies, but like geese, fish also take advantage of swimming in groups:
  
  Scientists show how fish save energy by swimming in schools [harvard.edu]
  
  And there have been many studies into dolphin and whale motion [gwu.edu].
  
  Hydrodynamic study into whale flippers [uci.edu]
  
  The use of rotary motors only seems to occur at the bacterial level (flagella bacteria [adelaide.edu.au])
