This is a thread to discuss smaller or general waifu building problems, solutions, proposals and questions that don't warrant a thread or touch on more than one topic. In a way this is a technical meta, minus news. Keep it technical. A lot of topics in the old thread here >>83 have a thread on their own by now. The main topics in the old thread with the link to the related dedicated threads are listed here - it was mostly about actuation at the beginning: Topics in the old OP: - liquid battery and cooling in one (flow batteries) >>5080 - artificial muscles (related to actuators >>12810) - high level and low level intelligence emulation (AI) (related to AI >>77 >>22 >>250 >>27 >>201) - wear and maintenance, including repairs - sanitation >>1627 (related to actuators >>12810) > cheap hydraulic and pneumatic muscles > woven sleeves out of strong nylon fishing line > exhaust excess heat by breathing and panting (related to thermal management >>234) >>1635 (related to energy systems >>5080) > sitting in her 'recharging chair' > swapable battery packs, air tanks > sleeve and other 'fabric' weaving TOOLS >>1691 -TOOLS- > automatic winding >>1698 -TOOLS- > looming mechanism >>1711 (related to actuators >>12810) > belt to transfer the mechanical energy to joints >>1715 (related to actuators >>12810) > not uncommon to use wires >>1716 (related to actuators >>12810) > double-end style towing sock cables (for hydraulics/pneumatics) >>1716 (related to actuators >>12810) > synchromesh drive systems >>1757 (related to actuators >>12810) > wires that themselves contract when heated >>1758 (related to actuators >>12810) > air muscles ... using an origami folding approach >>1779 (related to skin >>242) > self healing stretchable electronic skin >>1792 (related to actuators >>12810) > cable driven design >>1793 > klann linkages >>1799 > Jansen's Linkage >>1879 > software for waifu mechanical development >>1993 > hands (related to hand development >>4577) >>2032 >>2048 > decentralized computing of motion >>2377 (related to AI >>77 >>22 >>250 >>27 >>201) > AI and memory related, fuzzy NAND >>2670 --LIQUID-- > algae living in the internal water tanks >>2754 > copper for internal tanks >>2756 (related to vagoo / punani >>419) > slime onahole >>3182 (related to AI >>77 >>22 >>250 >>27 >>201) > combines MuZero, the Intrinsic Curiosity Module, Go-Explore, Hindsight Experience Replay and Divide-and-Conquer MCTS > pretty tough AI questions to solve >>3223 (related to AI >>77 >>22 >>250 >>27 >>201) > generally AI related thread >>3240 (related to AI >>77 >>22 >>250 >>27 >>201) > Flowtron ... autoregressive flow-based generative network for textto-speech synthesis >>3249 (related to AI >>77 >>22 >>250 >>27 >>201) > Tacotron, transformers >>3930 > intellectual humility >>4827 > most common methods to glue (3d printed) plastics together >>4831 > micro RC car, assembly of small stuff >>4861 > 90 facts about the human body >>5038 > DIY and inventors thread in the dollforum >>5448 > 3D printers to produce tensegrity structures >>5457 > silicone ball jointed doll ... held together by wire or string. >>5457 (related to skin >>242) > silicone skin covering the body with two layers of thin plastic in between ... skin feels like actual skin moving around >>5479 > Polyurethane foam to add plastic to the outside >>5487 > OpenLOCK >>5674 (related to actuators >>12810) > free spring calculator >>5928 (related to vision >>97) > lidar sensors for less than $100 >>5942 (related to organisation >>4143) > summarize papers and abstracts ... research sandbox >>5944 (related to AI >>77 >>22 >>250 >>27 >>201) > AI simulators >>6420 (related to energy systems >>5080) > alternative energy sources >>6503 (related to actuators >>12810) > compressor-free McKibben muscle using high-pressure electrolysis > hydrogen gas muscle >>6578 (related to AI >>77 >>22 >>250 >>27 >>201) > 'understanding'/real world context of the concept itself > quick mental images , AI, NLP >>6587 (related to AI >>77 >>22 >>250 >>27 >>201) > learning from artificial imagination > world models >>6845 > direct ethanol fuel cells >>6845 (related to AI >>77 >>22 >>250 >>27 >>201) > graph databases >>8311 (related to skin >>242) > fabric skin without silicone rubber > Mylar coated with aluminum > muscles should be fabric and a pliant closed cell foam (>>12810) > touch sensitive foam through carbon black and pressure changing resistance >>8312 (related to vagoo / punani >>419) > private parts could be like a pair of shorts with internal pockets for private parts. >>8314 >>8328 >>8361 (related to skin >>242) > Lycra, spandex, and elastane > full body suit >>8364 (related to actuators >>12810) > which bearing should be used in printed drives or in joints >>8369 > bearing types ....

>>39760 I agreed with putting the actuator post here. It's the one thing that justifies making a large scale R/D group. OTOH, I don't understand why we need to have artificial musculature. I would just focus on making a classical robot OTOH^2, I don't want to be a wet blanket, and as Tony Stark said, "Sometimes, you have to run before you can walk" I guess the real lesson is, we do need to have a unified vision and problems to solve. Robotics is such a huge field, and "Robot, female" hardly narrows it down.

>>39761 Grommet, I responded to the post in the other thread. Sorry for the confusion of thread-hopping - just following where the posts are. :) Regarding the financial concerns - I responded with >>39789 Admittedly, on the engineering, I'm out of my depth. As far as actuators are concerned - it's your best guess. But, I can try to help source whatever is required. I've been thinking about your post where you mentioned trying to source actuators (in the propaganda thread) - I'm on it as we speak. I'm reaching out to a few manufacturers to see what can be sourced. I will warn you though, it won't be cheap (hence why finances for manufacturing would be putting the cart before the horse, but finances for R&D would be, if I may be so bold, quite relevant to the current predicament of sourcing complex tech.) Your blathering is very appreciated, as it gives me an idea of what you guys might need. How would you feel about possibly spinning off manufacturing actuators to: >A. Raise funds to spend on other parts of the equation. >B. Actually perfect the manufacturing process, so that you have a usable product for implementing in your robowaifu. It'd be pretty feasible to raise funding on something like this. >>39776 Worry not, anon, I'm right on your tail. :) I'll just follow into whatever the relevant thread is to reply.

>>39768 >I don't understand why we need to have artificial musculature I have been assuming to get a real looking waifu you would need all, or most, of the muscles but...you made me think. I could until now not think of a way around this. What if......deleted most of my hastily derived thoughts... ...I'll have to think about this and see how the muscles can be made to appear contacting and extending properly. Well I thought about it and realized, I already thought about it. If you want something to move like a human then you're going to end up with 300 actuators or so. I counted up all the joints here, >22109 Now maybe a block thing that repeats,"warning Will Robinson" over and over will make some happy but I want something that can move all it's joints like a human and has the same physiology. This is just me but if it doesn't move like a human and have the same frame, though it could look very different, but humanoid. If not, then for me, why not just get a onahole? If it doesn't have a human physiology then it will have all sorts of trouble. It can't use human tools. It will constantly have to either have special tools or some sort of kludge to do most anything that's already set up for humans.

>>39805 Ah, I see the main difference between you and me. I don't mind (and am actually quite fond of) a robotic robowaifu, but you want one that is as close to human form as possible. Though I will say: you can get a lot of mobility from only 7 motors per arm >>39604 , combine that with a neck pivot motor, and you can have an animated upper body with only 15 motors.

>>39814 To be clear I'm not dismissing what you want in any way. I'm only saying what I want. And I expect that this sort of ascetic and techno aspect would be widely regarded as desirable among a large group of people. I want something that moves like a human. It doesn't have to necessarily look exactly like a human. Could be a fox girl (we could hope) or whatever, and easily be recognized as a robot, but I want it, how to explain, anthropomorphized, like how in cartoons they make animated animal characters move around and act like humans. This is just a natural thing that humans, myself included, find appealing. And to do this it will likely take 300 or so actuators.

Robowaifu Technician 08/17/2025 (Sun) 00:53:25 No.40337

There's a voltage multiplier circuit that I've been thinking about making, but don't really have any of the things I'd need to test it, but here's a crude drawing of what it'd look like. There's a battery that powers a high frequency square wave signal generator, which is connected to one plate of a 3-plate capacitor. The other 2 plates are connected to the positive and negative of the battery. I didn't really show it in the drawing, but it should be rolled so the capacitance between positive and negative, negative and AC, and AC and positive, should all be equal. A change in capacitance over time produces a change in voltage in a capacitor, the faster and greater the change, the greater the change in voltage. And if I'm right, it works better with a dense, high-K dielectric, and the AC signal counts as a change in capacitance, switching between being an extension of the other capacitors. Again, if I'm right, the output amperage would be nearly the same as the input, aside from losses, but the output voltage would be significantly higher.

>>40337 This sounds great, Anon. Any specific uses you plan for it? Good luck with this plan, Anon. Please keep us informed about your progress here. Cheers. :^)

Robowaifu Technician 08/18/2025 (Mon) 07:01:11 No.40384

>>40338 I made a post >>39165 about wanting to make a mono-thermoelectric cell based on an expired patent, where the whole cell converts heat to electricity, only needing to be heated, not having a 'cold' side. On the inventor's site it says he used a cell to run a clock with only room-temperature heat for over 10 years. I figure it can easily trickle-charge a battery from waste heat, but thought about making a fridge/air conditioner that would use some of the power generated to suck-in more heat from the environment & convert it to energy. While that idea might still be practical for making a fridge, an AC, or cooling a PC tower, the best solution would be to make a small, simple circuit that would cause the cell itself to cool under load while regulating the voltage output. I'd seen this patent: https://patents.google.com/patent/US4095162A which claims to act as a voltage multiplier the same way my doodle does, but instead of using AC and 3 plates, it uses 2 plates, one being a metal tube around a glass bulb & the other "plate" being ionizing & deionizing plasma inside the bulb to change the capacitance at high speeds. A copy of a letter from the inventor on rex research makes it seem like it creates free energy, and I have a theory on how that might be true, but it could just be a charge pump that's good at sucking the life out of a battery & maybe do that to the monothermal cell.

>>40384 Ah, yes. I remember that! Do you think you'll be able to obtain the materials, electronics, &tc., you'll need to make prototype assemblies anytime soon, Anon? Regardless, please keep us up to date here on your progress. Cheers. :^)

>>40385 I have basically no confidence when it comes to actually making anything myself. I live pretty much entirely in my own head. I might make a monothermal cell prototype soon, but I keep procrastinating because I'm afraid of fucking up, because I always do. That, and I'm not sure if the quality PVA glue I have is good enough. I've been trying to get help on Fiverr with some other circuits, but the ones that don't want to have an unnecessary & inconvenient Google Meet chat with me in broken English end up asking if I intend on making it a commercial product, or something else that seems like they're trying to squeeze as much money out of me as possible, when they don't just flat-out tell me "no". I've been trying to find help on it for 2 months now & haven't gotten anywhere.

>>40484 >>40485 I'm trying to use Fiverr for a more complex non-waifu project where I don't know where to begin making the circuit. >Get four diodes, a capacitor and crystal. Rated for what? I'm assuming I'd need a high-voltage diode, if it does multiply the voltage like I expect it to, but just "diode" is worthless to me because I don't want to waste time and money burning-out components. (or in case of my other project, electrocuting myself) and I find that with a lot of circuits posted online, either no component values are included at all, or a capacitor will state the voltage, but not the farads, or something like that. And any time I bring this up I usually get a bunch of "if you don't know, I'm not going to tell you" smartass replies that help nobody.

peteblank 08/19/2025 (Tue) 09:33:18 No.40488

>>40486 I asked gemini and it said if wouldnt work because its not pumping capacitors like a regular voltage multiplier. As for the values if the components youd use thd amount if capacitors to get the final voltage snd get diodes rated for that. The formula is 2*number if capacitors*voltage=final voltage. Also according to gemini. You can use lower value components at the beginning of the series to save a few nickles.

peteblank 08/20/2025 (Wed) 07:13:43 No.40509

>>40501 If its a regular voltage multiplier youd get the components rated for the final value. So if at the beginning its 5 volts(which you can get with those things that come with the arduino kits) and its 3 series youd get them rated for 3*2*5=30 volts in that case you can get the regular stuff 1n4001 diodes and Youd get a 50 volt rated capacitor thats say 220 nano farads. One of the first things i did was make a voltage multiplier.

>>40501 >I looked at the patent, and it actually reminded me of a plasma ball. What I've been trying to figure out is how to make it work without using plasma at all. It sounds cool, but isn't good for miniaturization, heat, or life expectancy of parts. The only other thing left to try is using magnetic fields to vary capacitance. And at that point I think it'd just be a fancy-looking transformer.

OTOH, I don't delude myself for even a moment that there are any """frenly""" demons!

And human beings have little spiritual powers (thankfully, given the rampant evils here) during this life for such things outside the purview & direct involvement of God or angels here on Earth. <---> My intent rather was to discuss the technical & marketing aspects of a product that -- at first glance -- seemed unlikely to succeed...yet became one of the biggest blockbuster products in history. That design team's focus on simplicity and low power consumption were the keys to their victory over their competitors. We here should do the same, IMO. >tl;dr This is how we will deliver basic robowaifu kits for ~US$2K-3.5K that can last all day on a single charge; while everyone else will be much more expensive / power-hungry during these initial years.

Qualcomm has been keeping up a very brisk pace for over a year now on their "Intelligent Robotics" SDK releases. https://docs.qualcomm.com/bundle/publicresource/topics/80-70020-260/robotics-sdk-july-2025.html --- One of the biggest PITA with so-called """ROS""", is the horrendous dependency hell involved with setting it up from scratch (along with it being incredibly finicky thereafter to bringing in new libs as well). Qualcomm apparently pulls some of ROS's core packages into their own SDK binaries, so the potential is there at least to eliminate this whole issue outright. If so, then that alone makes this Qualcomm system interesting IMO. Add in the likely support for the upcoming Arduino UNO Q board (cf. >>42176, et al), and this seems like a strong contender for our research here.
