Hello fellow Anons! Kiwi here to provide basic educational facts about various actuators we can use for gifting artificial avatars of our hearts desire motion!

1. Let's start with a personal favorite, the impractical, inefficient yet oh so fascinating: Heated Twisted Nylon!

What are they? They're nylon threads which have been spun around then annealed to seal in their coils. A heating method causes these threads to then contract or expand.

Good: Why is this a personal favorite? Simply put, it's natures muscle substitute for muscles. To elaborate, this marvelous invention contracts like human muscles, has a similar practical strength/weight/volume as human muscle. Icing on this proverbial cake comes in its incredibly low cost of manufacture. Materials needed are nylon threads and a heating element. A fixture for production can be produced simply, operated with incredible ease, all while having a low cost. It very well could have revolutionized all of robotics if it weren't for its flaws.

Bad: This is honestly a terrible actuator. Its greatest flaw comes from its speed. they aren't as fast as human muscles unless they're underwater. Water reduces efficiency to unacceptable levels if they're powered by batteries. Water is also rather heavy. If used, you'd have a waifu that moved slowly , would seize up in hot weather, and her battery would die rather quickly. Final nail in the coffin: it's very difficult to get positional control.

2: Pneumatics, moving her booty with air!
What is it? Pressurized air is guided to an actuator where its energy turns into motion. Popular air actuators include rotary turbines, cylinders, and air muscles.

Good: Actuators are light for their power. Positional control isn't difficult to attain. They can be faster then human muscles. Heating elements can be used to augment performance to higher levels.

Bad: These things require electrical actuators to function properly. Thus, they're inherently more complex then electrical counterparts. They need a source of compressed air, either from a tank or a compressor and a tank. Compressors are large, heavy, noisy, all around unsuitable to be incorporated into a waifu. Air tanks would also run out rapidly unless she's barely moving. Overall, they're suited better for industrial use.

3. Hydraulics, they're like pneumatics except stronger, needs a return system, needs an onboard pump, gets hotter, generally costs more, and is heavier.
(2 and 3 are great for stationary machinery which requires high power as they're very cost effective as high power actuators)

4. AC motors
What are they? They're rotary devices which use AC current to create magnetic flux used to provide torque.

Good: Generally highly efficient with good thermal characteristics. Can have controllable speed and torque.

Bad: They run off of AC electricity, batteries don't provide that. It's not difficult to change DC to AC but, it's a layer of extra cost and complexity. Overall they're great but the next actuator is better suited for our purpose.

5: DC motors are the ideal actuator for smaller waifus.
What are they? They're actuators which convert DC electricity into rotary mechanical energy.

Good: They're inexpensive, easily attainable, and simple to control. They're very easy to control. Uses DC which batteries provide.

Bad: Need to be geared down to provide good torque. They're middle of the road efficiency wise.

(For smaller waifus, their lower efficiency compared to the next actuator isn't a major concern. Smaller batteries recharge rapidly, so having her need to charge in her bed isn't a big deal.)

6. Superior Brushless Motors are ideal actuators
What are they? DC motors which need specialty hardware to drive them.

Good: High efficiency, it's the most efficient option available.

Bad: Controllers add expense and complexity.

I need to sort out her CAD files more before uploading them, but the .STLs are ready. Link to Google Drive shared folder: https://drive.google.com/drive/u/0/folders/1xWilMfWDZnrt30E1Uw7hlWe6JmaigKQF

So recently on /tech/ I expressed my interest to start creating my own waifu/partner chatbot(with voice and animated avatar) but wondered whether that is even possible now that I'm stuck with webdev. So one of the anons there pointed to me this board and where I can get started on nueral networks and achieving my dream. And when I came here and looked up the library/guide thread I sort of got very confused because it feels more like a general catalogue than an actual guide. Sometimes things are too advanced for me(like the chatbot thread which two replies in and people are already discussing topics too advanced for me like seq2seq and something else) or other times too basic for me(like basic ANN training which I had already done before and worse the basic programming threads). I know this might feel like asking to be spoonfed but best with me, I've been stuck in a webdev job for an year, so I might not be the smartest fag out there to figure it all myself. >=== -edit subject

A large amount of this board seems dedicated to hardware, what about the software end of the design spectrum, are there any good enough AI to use?

The only ones I know about offhand are TeaseAi and Personality Forge.

Introduction: As we know, creating an acceptable functional robowaifu requires knowledge and techniques from different areas. One of them is simulation, there are many modern easy to use Game development frameworks or tools like Godot, Unity and Unreal engine. But even if they come with easy to use out of the box IDEs you would need to create environments, collect or make assets and if you are willing to spread your work you will have to supply the other members with the source code and assets. Here is where opensimulator comes to the rescue. What is opensimulator?: Opensimulator is a .NET based technology (which runs perfectly on mono) that allows you to create distributed 3D world simulator environments and users can visit them and interact with them using different client/viewers. You can split your simulators and connect them into a public or private grid, and grids can allow users from other grids visit them its called hypegrid (you can see hypergrid as a 3D internet based on opensimulator) Here is the list of popular public opensimulator based grids: http://opensimulator.org/wiki/Grid_List If you are wondering how many active users there are you can make an idea using this hypegrid index: https://opensimworld.com/dir This technology is an opensource clone of a private platform called secondlife which unfortunately is not well known or underestimated is selled as a simple social 3D platform when in fact is a huge collaborative 3D development environment (in which even robowaifus exists). What can I do inside opensimulator?

Creating a functional Robowaifu is a yuge Systems Engineering problem. It is arguably the single most complex technical engineering project in history bar none, IMO. But don't be daunted by he scale of the problem anon (and you will be if you actually think deeply about it for long, hehe), nor discouraged. Like every other major technical advance, it's a progressive process. A little here, a little there. In the words of Sir Isaac Newton, "If I have seen further it is by standing on the shoulders of Giants." Progress in things like this happen not primarily by leaps of genius--though ofc that also occurs--but rather chiefly comes by incremental steps towards the objective. If there's anything I'm beginning to recognize in life it's that the key to success lies mainly in one unwavering agenda for your goals: Just don't quit.

'Sup anons? I am here to remind you guys something important, TO DO YOUR RESEARCH IN MULTIPLE LANGUAGES. Our mutual language is English however that is not enough. We need people who can speak those 3 important languages: Japanese, Chinese, Russian. I've been learning japanese for 4 months and with the help of dictionary I am able to understand basic stuff. Here is the point, there is a whole another world out there. 1) Chinese: Chinese people work under such hard circumstances and put really much effort into their jobs. Nearly none of the projects are translated into English since Google is banned at China. However there are a lot of great stuff there, I mean like even Microsoft runs their virtual woman project there. Since it is too hard for me to learn I generally use DeepL (best translator out there) and Baidu (Chinese search engine) and read latest researches and projects there. I wish I knew chinese well, in that case I would be able to find not-so-popular webpages and grab more information on topics. 2) Japanese: Even though good Japanese projects gets translated into English most of the research there gets translated only when the projects is ready to publish and sometimes they are too hard to find. I try to read as much AI papers in Japanese as I can. Scientists there do great stuff. I've seen a lot of robowomen projects there. You can also find some 3d printing projects for anime girls. Really worth looking. 3) Russian: Russian is the least important one in my opinion. But a professor of mine graduated from a university there and he has a lot of academic books that aren't translated to English. You would be amazed at how much work they have on stuff such as algorithm theory, artificial intelligence, computer science. Most of the stuff there are focused on "science" part of CS. So they are theory-weighted. So right now we need people who can speek Japanese and Chinese (Korean would be good as well, but there isn't that much of research there tbh) Using DeepL is enough to understand most of the pages but only a person with fluent Chinese/Japanese would be able to find goldmines deep there. I am pretty sure that there are hundreds of Chinese people working on robowaifu related projects that we are not aware of. Same applies for Japanese people, but since Chinese people are in a much worse situation it becomes really hard to find those people. Anyone has some recommendations? I wish I had time and skills to learn all those languages but I can only afford to learn one and I am going with Japanese since I have a dream of moving there in the future. We need to brainstorm on this issue.

Hi Anons, making a thread as suggested in >>10947 I've been thinking about this for a long while, and wanted to throw in a draft and see if anyone has comments/criticisms/additions. I present to you the draft of the Robowaifu Power and Control System (RPCS). This draft is by no means complete or definite, but it is a starting point. Let's call it version 0.1a. The version follows major.minor and a letter for bug-fixes. Minor is for feature addition/reduction, major for when we eventually get there XD. From a legal stand point, this is under CC0 or public domain (unless Chobitsu has specific licensing for the content on /robowaifu/). I intend for the draft to develop further and stay open for use by anyone. Summary A full-size robowaifu system needs several things: - Power distribution. Main system bus coming from a Li-ON battery (or other technology). One backup 5V emergency power supply used by slow communications to check appendage integrity, sensors etc. - Main processor. In this post I won't be delving into it in great detail, and mostly treating it as a black box. - Low/medium throughput communication for simple sensor, debug, or status information. Must be robust and must work before any high-level software is working (including the network stack). - High throughput communication for large data-logging, visual processing etc. - "Spine" or communication interconnect. Multiplexes many connections from many sub-systems to the main processor. Includes power distribution connection (allowing individual control to sub-systems). - Sub-systems to actually do the fun stuff! (Arms, legs, nekomimi ears, etc.) Terminology Brain refers to the main processor (and all of its sub-systems treated as a single unit).

Considering where we want to go, a robowaifu with brittle and fragile PCBs, soldering contacts and delicate wires is something which can and should be improved upon. Closed CPU architecture is key as well as the possibility to port the waifu to a new body if necessary. Several supplements and 6 shots of espresso later, I've sketched this (somewhat humorous but also somewhat serious) concept. This is only a processor and not a memory module, but there are a few things I wanted to bring up via this illustration 1. The idea of discarding the PCB model for something suspending in heat dissipating resin, mostly rigid, waterproof and shock resistant, those chips aren't going anywhere, plus it looks black/translucent and cool and we want our waifus aesthetic without clunky square innards. This gives it the mega-man memory crystal aesthetic 2. CPUs dedicated to specific types of processing. Do one job and do it well. a)Since our human brains are split into left-right, logical vs. abstract, I think it would be an advantage to have separate processors to say recall facts and perform calculations vs say, paint a picture or appreciate nature. The "creative" CPU may very well work like Google AI or something of that sort via self seeding feedback-recursion. (therefore our waifus can imagine and dream too). b)mirror neurons and environmental modeling: important for our waifu to understand that we are like her, and not simply another object like a chair or a tree. Gives her the ability to understand how to interact with others and the world via empathy by constantly comparing her own similar experiences with what she sees or experiences. This also requires an internal 3d spacial model of her environment which would be continually updates from sensory input, and like us, fuzzy logic assumption could fill in the gaps where necessary. I figure something like a GPU core array would do the trick here. c) Impetus motivational chip - basically the reward/dopamine system d) Safety or Hazard prevention Chip - would interface directly with the Environmental Simulation chip, any potential hazard or danger to herself or her owner (or even another, if she is the cause) would cause her to freeze or back up a step before assessing further. Would also be useful for necessary danger/pain avoidant reflexes and self preservation. I figure industrial (BUS for example) systems such as in factories or that manage car braking, steering, etc. would already be on the cutting edge of this and we might be able to borrow something from them. Ports would basically be for power and charging a small internal lithium battery and another strictly for I/O Use this thread for any elaboration on this concept, or feedback (or your own ideas if you think you have something better but along the same lines) -M.Ronin
