Body Proportions Robowaifu Technician 11/24/2021 (Wed) 01:35:27 No.14388 [Reply]
I don't know if this was covered already in an existing thread, but I thought I'd make a thread dedicated to body proportions. Obviously everyone has different ideas of what they want in a waifu and body proportions are no exception, but for the sake of discussion this is for a realistic adult, human, female of indefinite height. Height is especially tricky, since proportions play a huge role in perceived size. A lot of information on human body proportions easily available online are idealized, rather than realistic, which isn't a problem itself, but most is about men's body proportions, and often tend to self-contradicting. Common examples of idealized proportions are Vitruvian Man or the 'Physical characteristics of the Buddha', neither of which are very useful for waifus a Barbie dolls are a common example of unrealistic beauty standards, but deviate too much from reality to be seen as anything but Barbie dolls. The only consistently agreed on idealized proportions are an arm span matching the height, and legs that make up half of the height. Everything else seems to be completely up in the air. Any thoughts or resources on the subject would be appreciated.

I'd err more on the pragmatic side. Make the bot as big as it needs to be to accommodate the necessary internal components to facilitate locomotion. I think the happy medium of size and functionality is around 5 feet tall. I would imagine it would utilize child-like proportions, not to emulate kids but because it'd be cheaper and easier to perform maintenance on a bot with a smaller frame. It'd also be easier to store since it'd take up less space. It doesn't matter if the limb length or hip width is slightly exaggerated if it's for the sake of accommodating a bot's ability to navigate and interact with its environment. As far as the issue of "child sex" doll aspect, I'd simply have the external body looking more mechanical aesthetically.

Robowaifu Propaganda and Recruitment Robowaifu Technician 05/07/2020 (Thu) 05:39:42 No.2705 [Reply] [Last]
Attention drawfags and writefags! Your skills will be needed. The task of building and designing a robowaifu is a herculean quest. As great as this community is, /robowaifu/ simply does not have the manpower to real our goal of DIY robowaifus. Luckily for us there are several communities on the internet that we could find new recruits or allies to help us build our waifus: MGTOW - These guys know all about the legal pitfalls of marriage and the dangers of feminism. There is already a lot of talk about sex robots in MGTOW communities. It shouldn't be a hard sell to get them to come here. Incels - Guys that can't get laid. The opportunity for love and companionship should be enough to bring some of these guys over. We need to be careful when recruiting from some of their communities. We don't want to attract negative attention. Monster girls/furry/mlp fandoms - The only way these guys are going to be able to have their harpy/elf/goblin/anthro/pony/whatever gf is with a robowaifu. They have an interest in seeing us succeed. Again we need to be careful here not to attract the wrong kind of people that will bring us the wrong kind of attention. Male STEM students - Generally these guys aren't going to get laid until after they have established themselves. A robowaifu could really help them. This may be a harder sell because many of them have been brainwashed in university, but they have skills that we could really use. Transhumanists/biohackers - Many of the technologies involved in building a robowaifu could be used in transhumanist or biohacking applications such as building an avatar. They may have some interest in helping us out. We will need to be careful which transhumanist communities we go after as many of them are full of feminism, tumblr tier sexualities and genders, and SJW's. Cyberpunks and technophiles - These guys (and they are usually guys) are all around into technology and may just enjoy working on the kinds of projects we need to do. They are often into programming and AI.

Covert Ops Robowaifus Robowaifu Technician 03/11/2024 (Mon) 00:08:27 No.30233 [Reply]
I made this thread as an alternative to the existing battle droid waifu thread because I wanted to discuss actually plausible robowaifu combatives and not just post pictures of cool looking battle droid waifus without regard for realism. But every development path I tried led to something more like a special ops commando or assassin droid than a stereotypical battlemech. This is because most robowaifu enthusiasts will not be able to get their hands on military-grade weapons for legal and financial reasons. But an assassin droid doesn't need a lot of weaponry or armor. What will follow here is the best way to develop a fighting robowaifu that you can afford, according to me. Pic related; it's a robowaifu commando that I made using the AI art generator on NightCafe. >General design The best weapon focus for a robowaifu is undoubtedly guns. Guns are the easiest weapons to train humans to use and this will hold true for robots. It's also likely that robowaifus will be petite on average, both for affordability's sake and because that's what a lot of guys like. This will mean that she will have difficulty using martial arts. You can give her some supplemental training in grappling, the martial arts focus best suited to deal with larger opponents, but grappling fails against multiple opponents. Striking is the best for dealing with multiple opponents and short waifus are not good strikers. This is why the best bet is to equip her with incapacitating gadgets like tasers or tear gas instead of trying to have her fight normally. Also note that it will be far easier to program her to use a shield than a weapon - actually more like a pair of armguards to save weight. She can block most bullets using the armguards, but impact weapons will break through her guard. >Weapon selection When I made the OP picture, I asked for a handgun, a revolver and a pair of revolvers, but no matter what I tried, it just does not seem to understand the concept of pistols. But I realized that what it was giving me might be better than what I asked for. The way it has the drawing now renders her gun as a shoulder mount. I originally wanted to give a robowaifu dual pistols and have her fight with gun-fu Trinity-style, but this is much harder to program than a shoulder gun. A shoulder gun doesn't rely on complex hand movements which will have to be motion-captured and it would be quicker on the draw. As for which model of gun to use, you want something light and concealable that doesn't require too much ammo because ammo will weigh down your robowaifu, so rifles are right out, contrary to the lies of the picture. You also want the gun to not have too much recoil because your waifu is light and can't shoot the gun accurately if its recoil is too strong, so don't get a shotgun either. A heavy pistol like a Desert Eagle most likely gets the nod here for being small, light and powerful; you don't necessarily need a large-caliber handgun, but it will give her some armor piercing ability as heavy pistol rounds can be more powerful than intermediate cartridges at short range. Unfortunately these guns tend to have strong recoil. Other gun options: >Bullpup P90-looking large-caliber handgun (nobody has actually made this yet) >Needle/flechette gun for lower recoil and better armor penetration (needlers are less accurate and somewhat less effective against flesh than armor though) >Straight-up pew pew space blasters; your waifu is too small to have a decently powered laser, so try a pellet-shooting rail handgun or particle beam instead Other shoulder weapon possibilities: >Active Denial System (microwave cannon, sound cannon, seizure-inducing strobe lights, etc.) >Harpoon gun >Javelins

It's a great OP effort, OP. Really nice work, seriously. However, I'm going to have to lock this thread. I'm pretty adamantly opposed to the obvious choice of turning /robowaifu/ into /Terminatorz-R-Us/ . Unfortunately /k/ was baleeted by it's unsavory BO recently, or I'd suggest you recreate this there. As is, I'm not sure what else to tell you, other than to commend you again, apologize, and hope you understand. --- >the existing battle droid waifu thread I suppose that was an oversight on my part. I will lock that thread too; again, with my apologies to Anons. --- Sorry to be a stick in the mud about this Anons. I certainly understand both the appeal and the need. However our primary focus is robowaifus for companionship, not war-making. There will be plenty of companies like B*ston Dynamics, and other Globohomo-encumbered companies to fill that need. However, precious few to fill the actual need that Anons have for loving, helpful, charming, and opensauce robowaifus. Feel free to discuss addressing this issue in our /meta thread, Anons.

Computational Parallelism, Photonic ICs, Soft Robotics, and The Use of Low Power Analog Systems Robowaifu Technician 01/09/2024 (Tue) 19:32:19 No.28223 [Reply]
If we were to be realistic about creating robot wives capable of forming seemingly genuine human actions such as fine motor skills, emotion, and rational thought while resembling a human with a few non-human features, i think the best way to approach this is to embrace the usage of soft robotics, computational parallelism, photonic integrated circuits, and low power analog systems. Computational Parallelism: Divide and conquer algorithms are often used to solve computational problems by dividing tasks up into smaller problems, solving them individually, and combining the results together to form one big output. This generates faster results and is already possible to achieve with conventional hardware, but most conventional hardware is limited to the amount of cores needed to effectively solve problems this way on a larger scale. It's a big hindrance to the speed of operations like this, so we'll need something more powerful. There are ASICs available on the market that were engineered to be used this way. However, they're too expensive, which drives me to the possibility of using Photonic integrated circuits. Photonic ICs: Photonic IC are exactly as the name implies: Integrated Circuits that make the use of Photons to computational operations as opposed to electrons. Manufacturing Photonic ICs is relatively more cost effective than if you were to try manufacturing conventional silicon ICs. Another huge advantage is that we can solve computational problems much faster with less power using photons without generating heat the same way conventional ICs do with electrons. The biggest caveat here is that this is still being researched and that special tooling would need to be made for us to build these in house. Soft Robotics: Soft robotics are the best option for creating human-like bodies for robots. Even better is that they often don't require too much power to actuate joints or muscles. Most soft materials use for soft robots are cost effective enough to be made with commonly found materials. I personally think making use of alginate hydrogel would be a smart idea for use in robots waifus because it is hydrophilic, and anti microbial. It is commonly used in medical applications such as wound dressings and drug delivery systems. It is also non-toxic which makes it a perfect candidate for use in robot waifus. I'd also entertain the idea of using other soft materials in conjunction with it for better results. Primarily, it can be used in forming fat-like deposits, skin layers, and artificial internal organs for robot waifus. I think it may also be possible for us to create internal lubrication systems for it due to the fact that it is primarily water based. Low Power Analog Systems: Low power analog systems are vague in definition, but the general idea here is that we can use things such as fiber optic wires, digital-to-analog converter chips, and digitizers to create a type of artificial nervous system that communicates with the rest of the hardware running signal transmitters over echo state networks. It's hard for me to accurately describe my visualization of this, but by now, I'm sure you get the point already. The only problem left to solve is power. How to we obtain it, and how much can we use? I don't know, but if we take the low power-high tech approach, it probably wouldn't become too much of an issue. I think that maybe the best way would be to use electrochemcial energy in some type of internal fuel cell to generate power. All of the systems described above would require less power than if we tried to use servos and silicon chips. I's also say that maybe we could take more inspiration from nature to create bio-mimicking features that we would find desirable. A lot of this is speculation that i got from dipping my toes into various topics and picking out what i think could be useful to finally end the hypergamy going on in the west. This is largely a cultural issue that is mulifaceted in every way and our efforts could be in vain if the feminists and roastoids find a way to outlaw open source tech. Not only should we be focusing on building robot wives to flips the tables in the dating and sexual market, but to also consider political and economic alternatives that absolutely strip and decentralize power from the hands of the elite. I personally think agorism is the way to go but that is a another topic for another time. Let me know what you guys think. Am i an idiot, or am i onto something?

Datasets for Training AI Robowaifu Technician 04/09/2020 (Thu) 21:36:12 No.2300 [Reply] [Last]
Training AI and robowaifus requires immense amounts of data. It'd be useful to curate books and datasets to feed into our models or possibly build our own corpora to train on. The quality of data is really important. Garbage in is garbage out. The GPT2 pre-trained models for example are riddled with 'Advertisement' after paragraphs. Perhaps we can also discuss and share scripts for cleaning and preparing data here and anything else related to datasets. To start here are some large datasets I've found useful for training chatbots: >The Stanford Question Answering Dataset https://rajpurkar.github.io/SQuAD-explorer/ >Amazon QA http://jmcauley.ucsd.edu/data/amazon/qa/ >WikiText-103 https://blog.einstein.ai/the-wikitext-long-term-dependency-language-modeling-dataset/ >Arxiv Data from 24,000+ papers https://www.kaggle.com/neelshah18/arxivdataset >NIPS papers https://www.kaggle.com/benhamner/nips-papers >Frontiers in Neuroscience Journal Articles https://www.kaggle.com/markoarezina/frontiers-in-neuroscience-articles >Ubuntu Dialogue Corpus https://www.kaggle.com/rtatman/ubuntu-dialogue-corpus >4plebs.org data dump https://archive.org/details/4plebs-org-data-dump-2020-01 >The Movie Dialog Corpus https://www.kaggle.com/Cornell-University/movie-dialog-corpus >Common Crawl https://commoncrawl.org/the-data/

/robowaifu/ + /all things monster girl/; it's benefits, projects, the uncanny valley, etc. Robowaifu Technician 05/03/2021 (Mon) 14:02:40 No.10259 [Reply] [Last]
Discussing the potential benefits of creating monster girls via robotics instead of 1 to 1 replicas of humans and what parts can be substituted to get them in production as soon as possible. Firstly is the fact that many of the animal parts that could be substituted for human one are much simpler to work with than the human appendages, which have a ton of bones and complex joints in the hands and feet, My primary example of this is bird/harpy species (image 1), which have relatively simple structures and much less complexity in the hands and feet. For example, the wings of the bird species typically only have around three or four joints total, compared to the twenty-seven in the human hand, while the legs typically only have two or three, compared to the thirty-three in the human foot. As you can guess, having to work with a tenth of the bones and joints and opposable thumbs and all that shit makes things incredibly easier to work with. And while I used bird species as an example, the same argument could be put forward for MG species with paws and other more simplistic appendages, such as Bogey (image 2) and insect hybrids (image 3). Secondly is intentionally making it appear to not be human in order to circumvent the uncanny valley. It's incredibly difficult to make completely convincing human movement, and one of the simplest ways around that is just to suspend the need for it entirely. We as humans are incredibly sensitive to the uncanny valley of our own species, even something as benign as a prosthetic limb can trigger it, but if we were to create something that we don't expect to move in such a way, it's theoretically entirely possible to just not have to deal with it (for the extremities part of it, anyways), leaving more time to focus on other aspects, such as the face. On the topic of face, so too could slight things be substituted there (again for instance, insect girls), in order to draw attention away from the uncanny valley until technology is advanced enough that said uncanny valley can be eliminated entirely. These possibilities, while certainly not to the taste of every anon, could be used as a way to accelerate production to the point that it picks up investors and begins to breed competition and innovation among people with wayyyyyyy more money and manpower than us, which I believe should be the endgoal for this board as a whole. . Any ideas or input is sincerely appreciated.

>>25707 >>26014 > The conclusion I came to was that you’d need at least 5 separate contractile regions, all independently addressable, AND able to contract dY for the snake-bot to be capable of any generalized sort of locomotion. Yes, that's just what the design I described should do. By having the cable winches attached to several disc vertebrae down-body from each winch, the overlap of each set of cables emulates the overlap of muscles in a snake's body. In this way the contraction of each set of cables can be individually controlled to either stand alone or gang together over a distance of several vertebrae, and the size of each "muscle" group (and therefore the number of muscle groups) can be varied on the fly by the controlling code. The operation of the cable winch groups can be done in sequence along the body to emulate the sinuous movement of a snake, and the winch-and-cable sets in the vertical plane for coiling the body can be used to adjust the areas of contact with the surface the body is moving over. To be clear, each vertebra is attached to several winches by cables, and can be acted upon by one or any number of the cables attached to it. The force of each winch is spread over several vertebrae, but several winches acting on each vertebrae combine to increase the force applied. By varying the spacing of the vertebrae discs, the diameter of each vertebrae disc, vs the diameter of the foam body and the resiliency of the foam used for the body (say 8" dia. vertebrae spaced 6" and 12" body dia.), it should be possible for the coils to be as tight as a few inches. With a larger sized object, like anon's body, our lamia should have no problem exerting a firm grip. As with an arachne, anon should probably have a safe word. Something I didn't think of before, real snakes are able to do a twisting motion with at least the forward part of their bodies, so we may also want to copy that. The 18" body size I mentioned before was at the "hip" area before the tapering of the snake body. I should have made that clear. >https://pubmed.ncbi.nlm.nih.gov/32271916/ (source analysis) >https://pubmed.ncbi.nlm.nih.gov/36296136/ (proposed robotic design based on analysis) Thanks, I'll take a look at these when I have a chance. >===

So each of our spider-girl's legs must be able to support 1/4 of her total weight, plus whatever extra we decide on for contingencies. That could be 1/3 of the total weight (maybe a little more?), in case one leg is disabled, so she could still safely walk to her service area (if the code isn't smart enough to adapt to a broken leg). Or if you are feeling particularly ambitious you might want her strong enough to carry her own weight plus anon's weight (plus excess safety margin) for when she needs to carry anon somewhere after demonstrating her web-spinning. In that case only four legs might be walking so 3 on the ground at all times, a quadruped. Here's a site with a good description of how spider legs work: Leg Uses Hydraulics and Muscle Flex https://asknature.org/strategy/leg-uses-hydraulics-and-muscle-flex/ Here's a paper on soft robotic spider legs cited on the website^.

Not sure how difficult it would be with servos w/o some dissassembly but with electrical motors regardless of type you can closely aproximate their % load by how much current they draw relative to max allowed which should not be difficult to track via analog inputs. Some simple algorithm would then calculate how many legs may be in air at any time and how far can legs neighbouring strained limb move to offset its load.

>>25617 There is now a printable version of the robot spider, so it should be much easier to build for anyone who wants a model to develop and test code for the legs: https://www.thingiverse.com/thing:3620761

/waifu energy source general/ What do you think that our waifus will use for energy?And how much energy it needs to use?From my rough calculations if will need about 2kw for the computer plus 500w for the mechanical part(although I am not sure about the last part because I am not very familiar with the mechatronics ). Surely we don't want to use something like an engine because of the noise ,vibrations and the exhaust.The current state of the battery is not suitable for our goals because of the low energy density (energy per square meter).I think that PEM battery will be a good choice because of the lack mechanical parts , huge energy density , the energy is in the form of electricity.The only downside , for now , is the fact that the PEM layer is VERY expensive ,at least for now . What do you think?What kind of energy source our waifus will use? >=== original Batteries & Power thread >>23

Two words. Atomic slug. Advantages. She stays warm. Very warm. Disadvantages. Your arms fall off and she has to chew your food for you.

>>28697 Imagine pic-related happening sufficiently-fast to turn that little crankshaft at 30K RPMs. > >via our neighbors at /late/
>>28724 btw the Mazda ones eat their own triangles at 10k-11k rpm... I doubt if the 787Bs touched 12k to still get through the 24 hours. I'm sure smaller sorts have lower rotating mass and things, but the point is that having turbines /= RPMs necessarily. Also, nobody is going to want to share an enclosed space with a smog rotor. You're really talking about an outdoors-only device by that point. Maybe try hydrogen or something idk If you're interested in outdoors miniature engines and things there's a man who's made a prototype sterling engine out of a Chrysler air conditioning compressor, his channel is called kirkolator1. I'm not sure if he ever reached viability with his project or not, but the point was that any unrefined "fuel oil" could work just the same as the propane he was utilising.
>>28734 >Also, nobody is going to want to share an enclosed space with a smog rotor. You're really talking about an outdoors-only device by that point. I wrote that I meant it for outside. That said, if the noise was dampened by the body and the exhaust captured or filtered, then letting it run for a few minutes might be okay in some edge cases, e.g. lifting something heavy or climbing stairs. >Maybe try hydrogen or something idk Even if, then this conventional fuel engine is worth mentioning. I don't try anything about this anytime soon, I just wanted to have it in mind as an option. Hydrogen is hard to store and not very energy dense, btw. Ethanol would be quite interesting. At the end of the day, whatever works for the specific use case is the right choice. This is meant as an option, and needs to be as small and light as possible, durable and with easy access to fuel. > interested in outdoors miniature engines and things there's a man who's made a prototype sterling engine This could be generally interesting, but I didn't even look if there was a Sterling engine for this use case, because I think they tend to be bigger. If anything then it would need to be very small and maybe could be used with steam. A waifu could gather sunlight with heatpipes under the skin and create steam and then use that to run the engine. Once again, this would only be for outside. More like this one: https://www.youtube.com/shorts/YKrdfjO9SBg - so if it is not needed then the additional wheight won't matter, also the smaller it is the better we can dampen the noise.
