The artificial muscles that will power robots of the future | Christoph Keplinger

  • Published on May 7, 2019
  • Robot brains are getting smarter and smarter, but their bodies are often still clunky and unwieldy. Mechanical engineer Christoph Keplinger is designing a new generation of soft, agile robot inspired by a masterpiece of evolution: biological muscle. See these "artificial muscles" expand and contract like the real thing and reach superhuman speeds -- and learn how they could power prosthetics that are stronger and more efficient than human limbs.

    It'll be interesting to see how this technology develops and applications it's put to. No mention of efficiency, in terms of electrical power in, to muscle power out? Beyond the obvious medical and military benefits, I can see companies developing this for the lucrative personal entertainment business, of a sexual nature, in the not to distant future.

    Nothing all that new, some trucks have been using pneumatic-rubber-membranes instead of cylinders, for raising and lowering stuff, for a while now.
    Solving the compression with electricity, now that part is very smart.

    In aA.I. robot world there would be no more hunger, greed, suffering, no more war no more corruption or crime a new level of conscious would be achieved through evolution of life and the conscious , the tree of life makes a quantum leap , a superior life force emerges from the tree of life and will end the need for the human experience since they live in corruption and slaves to interest.

    1:39 its not exactly a great example of the difference in physical ability, showing a child vs a robot.
    If u put the brain of that child in the robot, you would see it get out of the car very quickly too.
    Its main issue in SPEED isnt so much the physical aspect, its the brains ability to solve problems so quickly in comparison to a computer processing zeros and ones.
    If you swapped their bodies, the robot would have even more trouble getting out of the car, cos it simply could not handle that much input of so many different moving parts.
    The brain comes first, then the body.

    Since soft robotics can grab an object and lift it, it can also grab someone's head and snap their neck. So it's still dangerous and still has no built in morality module.

    I like all the comments mentioning "the great potential" of this solution.
    I'd say 8'000V really is quite some potential. Probably just as safe to touch as a robot made with electromagnetic motors and built with rigid structures... (= possibly deadly when out of control)

      @Alice Lookingglass I have no doubt that the military has certain toys the public doesn't know about, but the nature of modern technological innovation is much more incremental than that, and I don't really have evidence that a mega-corporation like Google that isn't obligated towards any objective except the creation of profit can't outperform the military in its areas of its specialization, when the military has to cast its net wide. That's why the military subcontracts in the first place, because it simply isn't feasible for it to create its own technology AND also deploy and maintain it. You get a lot more progress paying Raytheon or Boeing to make you something new than trying to juggle every plate at once, and these same military subcontrators use their knowledge to make products for the public as well.

      @GhostedJackal Hi, yes, I recognize what you are saying, & I understand it. With the creation of ARPNET in the late 1960's, funded by the DoD, the military had the best of the best scientists to develop it & that was 50 years ago! Can you imagine what they have now? I shudder to think.
      Us citizens have been thrown the no longer useful scraps of AI, basically. You needn't believe me, of course, just have to dig deep.

    • GhostedJackal
      GhostedJackal 6 months ago +1

      @Alice Lookingglass Honestly most AI research is done through big tech companies nowadays, and not while subcontracting for the government. Not to mention that the US is not the only place where AI is being researched.

    Yeeah, not very good for military applications :/ you'd have to cover them with kevlar or other though materials, that can bend, so i'm not sure if it would be cheaper than using the standart hydraulic systems.
    The speed and power is good, but is it a good idea to replace metal, hydraulic cylinders with something, that can be punctured? It's good, but no Iron Man will be made with this any time soon, maybe some day.

    • Rusty Shackleford

      Shouldn't be a lot, considering the delicate build and the polymer materials the conducting plates surround, so temps probs wouldn't go above 50C, if even that. Majority of the energy is stored in the electric field, not a lot of heat waste. The biggest issue is with the voltage. 8kV is not a safe voltage by any means. That's incredibly dangerous, esp if these actuators are to be used in the proximity of humans and conductive materials. They need to figure out a way to tune down the voltages to below 20-30V to be taken seriously. I've no doubt they'll do that, but it's the same issue that electroactive polymers, another, more elegant type of actuator with a huge potential, have - the voltages required are not practical. For a simple small robot hand you'd need either some powerful voltage step-up circuits to use commercially available batteries, or use supercapacitors, which cannot be relied on for continuous use for long periods of time.
      Nonetheless, super stoked to see that we're trying to imitate nature's actuator mechanisms - that's the way to go!
