    Ok, yeah, interesting video but...mate, wind your neck in, turn your mouth off and let the interesting people talk. Yeah, I get it, you love yourself and you love the sound of your own voice and you have a massive ego to feed but FFS the professor is way more interesting than you but you just wouldn't let the guy talk. I nearly turned off this video because of you annoyingly interrupting the interesting guy all the time but I stayed with it because I wanted to hear what he had to say.

    I am really into bicycles. And to see a freaky bicycle already makes my head turn. But to try and imagine what such mechanisms could do on bikey ... that makes my mind spin. And that is just the small application I could relate to, but ... I never say that, I just avoid that term whenever I can, but this is AMAZING.

    My main concern is fatigue at the bending point. While their tests show it can handle millions of cycles, it would have been nice to have a reference against a hinged equivalent. Does the lower price, weight and complexity of the compliant mechanisms bring with it a lower durability? For example, being ten times as cheap, but 100 times less durable than hinges, would (depending on application of course) make it the lesser option. Either way, a very interesting video.

    You meet smart people as you live your life. It is easy as a relatively intelligent person to not see the gap in other smart people and yourself all the time. (the obvious mega geniuses not included) "You are smart, that girl is sharp, what about my old professor?..... sure he is brainy too!" But when you see a guy like this making simple devices that are conceived and executed so perfectly, you can't help but be proud to be human... i'm not him but i'm on the same team as him.

    This all looks incredible, but what's really scratching at my suspension of disbelief is how there is not one mention of metal/plastic fatigue - the single largest apparent obstacle to flexible machines, apart from the little bit where they claimed to have so reached so many repetitions in their stress testing. I'm not saying it's impossible, or even casting doubt on their ability to do it, I just wanna know how exactly they make it not an issue.

    I think the idea of 3d print-ability is what gives these things extreme credit....I imagine us going back to the mechanical computer age so that parts can be easily replaced with 3d printed materials. This would be, in my opinion, an absolute necessity for space travel and colonization, as a 3d printer is much lighter than bringing an entire microchip fabrication machine.

    I found this really interesting and I wonder if it's a hard sell to convince some engineers to accept the reliability of compliant mechanisms (given that, in the real world, 'living hinges' have been extant for a long time in cheap consumer plastic goods, and are often very poorly implemented)

  68. Chris Colon

    Chris ColonIl y a 7 heures

    I think the only problem with these weird type of mechanism is, if they break, you have to replace the entire piece. I don't think its as easy as welding it back together, which it may, but the integrity of the mechanism wouldn't be the same.

    I've often wondered about what life could look like on other planets, and about how the mechanical processes of animals could be enacted by different biological processes. Like, why does everything on Earth use flesh and bone and muscles? Could you have an animal that use gears and shafts and electric motors? How would it compare to an Earthly animal of the same size? Well, the more I learn, the more I realize that life on Earth is actually built EXTREMELY well in terms of overall design philosophy. Take the principles in this video, for example. Flesh and bone and muscles don't wear out nearly as fast as mechanical components like gears and hinges, don't really need maintenance, don't cause friction by rubbing on each other, don't have any gaps or seams where stuff like rocks or sand could get caught, and can absorb pretty hard impacts without sustaining major damage. With possible exception of bones and teeth, we're entirely built out of compliant mechanisms, from the protein to the ligaments. It's an ingenious structure, and it works really well. I don't know that human science will ever get metal robots that perform as well as human bodies do.

    This isn't news to me. I have a pair of non-conductive needle nose pliers, molded as a single piece of plastic, that my father used in his TV repair shop in the 1960s. Companies have been manufacturing things like this for a very long time. Any trip to a dollar store will reveal dozens of "compliant mechanisms". The miniaturization aspect is cool, though.
