    I'm not any kind of professional so if this is stupid advice just ignore it. I am not perfect at anatomy but I think you need to make a nose bone because it can hold that skin that's being stretched. The cartilage on peoples noses holds the nose up but the skin on the face seems to be also held from that point too I assume with the ears also falling into alignment there as well. Kind of like an imaginary line from nose to ears being at the right alignment - there is cheek muscles and nose cartilage grafting onto the bone / skull. I would put a spacer where the nose bone would be and have it make surface tension kind of similar to what you did with the eyelids.

    • @DaveMakes
      @DaveMakes  3 дня назад +19

      I think you're right. Some kind of nose bone, maybe with a bit of an adjustable hook(s) so I can make minor adjustments to the tension - pulling the nose-bridge inwards a bit. Best case scenario would be a little knob I can turn to tighten it a bit after i've got the face on there.

    I did an experiment with your vidoes. I showed them to several groups of friends. For someone I casually introduced it as "check what this guy made". For the other I introduced ot as "check out what this woman made". Fascinating results, nearly everyone going in thinking a woman made it was creeped out but ultimately said it was really cool too. Meanwhile the introduced as man groups were also creeped out but got comments like "he needs to be arrested", and "he shouldn't be allowed near this". Interestingly someone in the introduced as a woman group thought it wasn't a woman, because as she said "women don't film like that"

    I'm not too sure why RUclips randomly recommended this video to me, but I'm glad it did, and I've been binge watching the entire series since. Very impressive to watch how it's all been coming together, and all the various design iterations.
    One of the first anime I ever watched was "Chobits", and as a teen, I had a bit of a crush on the character "Cameron" from "Terminator: The Sarah Connor Chronicles", so I've also kind of had a weird interest in female androids for a long time. Keep up the good work, and I'll definitely be interested to see how this project progresses over time 🙂

    Regarding the skin below the eye, you could use the same velcro technique you used for the eyelid. But since you need that bottom skin to be tight against the face, you could attach the velcro to a little threaded panel, and you could turn a screw in the back to adjust the depth of the panel. Or instead of a screw, you could use a rubber band in the back or something. But the main point is the velcro pad attached to a panel that is pulled backwards towards the face. And the way the silicone is bound to the velcro, it should be a an effective way of keeping the skin from sagging

    To simulate the mechanical binding effect of the velcro loops without the added thickness of the velcro, do you think printing the plastic of the eyelid with perforations for the silicone to anchor itself through would work? It would require some silicone to end up on the back side of the eyelid to form a wider mass that can't fit back through the perforations, but I don't know if that would be a problem.

    • @DaveMakes

  • @ghiktheoriginal
    @ghiktheoriginal 2 дня назад +2

    for the skin stretch problem you could really just use magnets to pull certain parts of it together like in the nose since that isnt a part that will be moved alot it would also maybe help with the eye gap a bit, or you prob plan on adding it but you could just add a temporary bottom eyelid just to hold it and fix the gap issue + the gap when she blinks, but idk im no expert im just guessing lol anyway, i love the project keep the awesome work my man, i hope to one day be able to do something like this.

    Velcro is very nice work really. I thought it would look clunky at first, but its not. About face deformation.. maybe same velcro "frame" for overall face? like snowboard-glasses-shaped (but flat) frame with same velcro? so it won't affect eyes, but will "save" nose and things out of the eye/brows area. I think it will work pretty well. same velcro for the chin and parts of the jaw, cheeks maybe more free tho (like what if you invent some-kind of way for her to be able to puff and "suck in" the cheeks, etc, who knows?) overall super nice upgrade, keep up the great work, for the future!

    Awesome work, I am once again in awe of how far this project has come. I love the new motors which don't make a sound. I always look forward to your update videos, this is so cool!
    On that note, once you cover up all the electronics, I would assume most sounds coming from the robot as masked and therefore muted?
    Also, would it be possible for you to post a video in the future showcasing the speed and power of the motors? I am very curious to see how fast the head is capable of moving/turning.

    • @DaveMakes
      @DaveMakes  3 дня назад

    • @VirgilAllenMoore
      @VirgilAllenMoore 3 дня назад +1

      @DaveMakes they use hydraulics instead of motors, and it produces a very humanoid movement. It's basically simulated tendons and muscle. Even with only a simple clothing sleeve like spandex, it looks very convincing. Almost like a hand wearing an opera glove over a gaunt arm.
      At some point they'll be looking to do aesthetic improvements with their models. It might be a good time now to get in touch with them so you're on their radar when they get to that step.
      Again, just a suggestion. They haven't actually gotten one of their models to walk yet, but they're currently developing the lower body now.
      If you were able to get on their design team for the aesthetic portion, they could release anime robots, which would of course sell like hotcakes. Then all they'd have to do is get a licensing deal for the character Hatsune Miku. And it would be like printing gold.
      Good luck.
      And I'll keep an eye out for your videos over the years.

      the motors for the neck are GM5208-12's, and other smaller gimbal motors in the head. Typically used for camera gimbals I think.
      I'm thinking 7 axis for an arm, and some greatly simplified hand shape. Maybe built around the idea of having a single motor articulating one particular grasp very well with some linkages, but no others. Interchangeable hands for different grips maybe? Not sure, probably i'll change my mind a dozen times before I get down to the hands.

      lots of distributed microcontrollers set up to receive simple position instructions from some master controller. I will likely try doing this wirelessly. Hannahs brain can be a desktop computer nearby, without having to be inside her. I imagine a large variety of movement behaviours, poses, actions and blends of actions to be situationally addressed by an LLM that chooses which motions are the most appropriate at any given moment. In a rudimentary way, an example I can think of would be the Bing chatbot. It uses a lot of emoticons, and it does so fairly naturally in appropriate situations. Those emoticons can be translated into a variety of motions or poses. A bit of sensor awareness in the robot can further modify the way the emoticons are inflected, taking into account people in the environment and other things as well.
      That's what i'm thinking at the moment, but it will be a bit of time before I can get around to doing it.
