Flying Robot Bird Unveiled 152

mikejuk writes "Festo, well known for their biologically inspired robots, have a new creation called SmartBird. It is amazing to watch and all the more amazing when you realize that it flaps its wings and all of the control is via a torsion drive which twists the wings during each flap. The whole thing depends on the constant intervention of the software to keep it under control."

    That seems to be a fairly well understood problem. Hasn't pretty much every fighter aircraft from the 1970's F16 onward required such software intervention? Inherent flight instability being leveraged for greater performance?

      And also, real bird also depend on constant intervention of the software, i.e brain. Usually when birds lose their heads, they stop flying. Or so I've heard.

      • This calls for immediate discussion!
      • And also, real bird also depend on constant intervention of the software, i.e brain.

        Birds have not evolved to handle inherently aerodynamically unstable systems. The demands on their brains are probably closer to the human pilot flying older inherently stable designs than more modern designs that can't fly without thousands of corrections per second on multiple control surfaces controlled by computers.

        • I don't think so. Most of the 'stabilization hard- and software' of the birds is probably built-in into the autonomous neurological network, just like a human is able to walk/run/jump upright - which is inherently unstable - without having to consciuously micromanage all muscles that are involved.
          • In fact, our brains do more than that. We can consciously learn to do things, then pass to a stage of being aware of what we are doing, then do something without conscious thought. Sometimes I drive to work with hardly a conscious thought about the process, sometimes in hazardous conditions (ice, school moms) I'm conscious of what I'm doing all the time. Anyone who has watched young birds learning to fly knows that they go through this process. I've watched a young jackdaw practice, over and over, flying fr

              I think you're mixing up two things. Yes, the physical aspects of driving (changing gear, choosing the right brake pedal, steering) become sub-conscious, but you should always be aware when you are driving of what is going on, whether it's ice, soccer moms, cyclists ahead, pedestrians at the side of the road, a driver about to pull out in front of you, or whatever.

      Yes, but any model plane that size doesn't require intervention from software to keep it under control.

  • Obviously the bird in the video isn't to the point of being to perform in the same way as our Harriers, but we are definitely seeing the future of military aircrafts. Our fighter jets out perform nature in many ways, but one only has to go outside for a few minutes to see bird after bird perform in ways that makes every current aircraft pale in comparison. This is a demonstration that gets the ball rolling.

      Huh? Birds are a lot smaller, so scaling is on their side. Also, they are built of flight, unlike human pilots. And I wouldn't like to see a bird get *close* to Mach 1.

      UAV will be much more impressive. But the Air Force doesn't like them, as it makes pilots obsolete.

        • I remember reading about a software pilot using neural networks that could outperform any human fighter pilot in simulations (not least because it could keep working fine at 8Gs or more). The military didn't want to use it because the down side of a neural net is that the programmer doesn't really understand how it works. The advantage of autonomous drones is pretty obvious - an enemy can't disable them with an RF jammer. The down side is that you need to be completely sure that the software is correct,

      Fighters already exceed the capability of the pilot in terms of maneveuring - it doesn't matter if you make the planes even better the pilot will still black out/die anyway.

      Why do no ornithopters employ feather analogs? They all have solid wings. Flight feathers form a check valve, letting air through the wing on the upstroke, and capturing it on the downstroke. This arrangement allows the bird to put a lot less energy into the upstroke (and thus not lose as much altitude). With a solid wing, you wind up pushing the craft down on the upstroke almost as much as you lift it on the downstroke.
      • I'm not saying you're wrong,but the point of flapping is thrust not lift.
        • I'm not saying you're wrong,but the point of flapping is thrust not lift.

          It's both, actually. However, a wing is probably not going to generate a lot of lift on the upstroke, so why pour a lot of energy into it? When you look at bird musculature, they have huge muscles for pulling the wing down, but for pulling it up - not so much.

      • I'm not an expert on flapping-wing aircraft, but you can also acheive low drag on upstroke by rotating the wing so it has the lowest angle-of-attack, and then turning it back so it blocks the most wind on the downstroke.

        Birds, having been created by the blind idiot-god evolution, favored (in the appropriate non-intelligent sense) wings that didn't have to do such tricks -- like you say, with feathers, you need a relatively simple flapping motion because they automatically reduce profile on the upstroke and

    We still have to crack the energy issue. We lack both reliable ways to gather energy, and reliable ways to store it.

    b) AI

Until we realize that we can produce as much as we need of just about anything, and that we are limiting ourselves by creating artificial scarcity to keep alive a system that's been dead for a long time, we won't make that breakthrough into what we thought the year 2000 was going to be.

        We're not far off having distributed manufacturing able to make shit for us for very low cost (almost free). But there's no way our current economic model can survive that. Given the amount of hassle we're dealing with because we can make copies of songs for free, what are we going to have to cope with when we can make copies of cars for free?

How are you going to share that among all humans? Time share? Ha ha.

          You could only make free copies of a car if there were a limitless supply of energy and raw materials. That rather sweeping assumption makes comparison with digital copying irrelevant.

    • Certain things are by their nature difficult and I don't think it's reasonable to expect these things to be solvable.

      a) My expectation is that if there were any really good ways of gathering and storing energy, then lower life-forms would be able to exploit these without having to go through the trouble of evolving into higher lifeforms and then figuring it out. You also have the inherent issue that forms of energy which store well are the most difficult to collect.

        Why do you expect that? We have designed many systems that are in some specific ways better than those systems found in nature. We can go faster, go further, see more, see smaller things, process numbers faster, store more numbers, and do heaps of other things better than natural systems can.

      • regarding (a): fat is a good way of storing energy. I'm not sure if I understood my highschool chemistry teacher right, but he said storing energy in fat is better than current rechargeable battery technology (note that this was around ten years ago, so it may not be true now).

        • The energy density of fat is close to that of Diesel fuel. Tank weight for battery weight, a Diesel car has more than 6 times the range of a battery powered car. (Nissan Leaf 100 miles, equivalent Nissan European Diesel approx. 600 miles.)

      This is true, or not--it really is a matter of personal perspective. I myself think we are making fairly equitable process in terms of the limited resources we are splitting between all of our priorities:

      We are still in diapers in weak AI, and not even started in strong AI.

      Might as well be saying this in the year 1850 in respect to clockwork men. The human brain is not software so much as it is hardware, and modern transistor chips do not resemble it very well. I think our present level of AI is fairly suited to the sort of computers we are manufacturing. Get quantum computers (in which we are make quite excellent progress) up to where large chips are viable, and I think the code development of AI will be a few orders of magnitude more viable as well.

      We still have to crack the energy issue. We lack both reliable ways to gather energy, and reliable ways to store it.

      We can generate massive (nuclear) and store massive (dam) amounts of energy. Scaling it down becomes more troublesome. But the real issue is that it's easier to dream up ways to use energy than to produce it, due to troublesome and altogether uncircumventable laws of thermodynamics, which in one sense will always make us seem like we're lagging. Energy "does stuff," and we'll almost always want to "do as much stuff" as we can, which can always be translated into some kind of gain. Getting back to the AI issue: there are fundamental constraints on the the amount of computation that can be done per joule of energy expended. And will we ever be happy with the amount of computing we do? I don't think so. So, in that respect alone, we already have some desire for infinite energy, to say nothing of whatever finite supply we have at a given time.

      We are still based on the stupid principle of scarcity. Until we realize that we can produce as much as we need of just about anything, and that we are limiting ourselves by creating artificial scarcity to keep alive a system that's been dead for a long time, we won't make that breakthrough into what we thought the year 2000 was going to be.

      Humanity always produces as much as it needs. If not, people die and the equilibrium is re-established. It comes to producing as much as we want, and that, as given in one example, is pretty much limitless. Scarcity of resources in that respect is inevitable and the distribution of those resources is fairly well addressed by capitalism. I doubt there will be a better way to distribute them until our super-AI comes online to figure it all out for us. Until then, humans are provably terrible at guessing where resources should go by any means other than rational self-interest.

      What do you mean "started"? Weak AI is the path to strong AI, it's not binary, it's a spectrum and at some point weak AI research will develop enough for the fruits of it to cross the boundaries into strong AI. Weak AI IS a start towards strong AI, strong AI isn't something we can just jump into blind.
