Henlo anons, Stumbled here via youtube rabbit hole & thought I'd share my little side project. Started out as just an elaborate way to do some mech R&D (making a system to generate animation files on windows blender and export/transfer them to a raspberry pi system) and found tinkering with the various python libraries a kinda neat way to pass the time when whether doesn't permit my outside mech work. Plus I'd end up with a booth babe that I don't have to pay or worry about running off with a convention attendee. Currently running voice commands via google speech and chatgpt integration but I'm looking into offline/local stuff like openchat. WEF and such are so desperate to make a totalitarian cyberpunk dystopia I might as well make the fun bits to go along with it. And yes. Chicks do dig giant robots.

The Sumomo Project Chobitsu Board owner 11/24/2021 (Wed) 17:27:18 No.14409 [Reply] [Last]
So I've been working for a while at devising an integrated approach to help manage some of the software complexity we are surely going to encounter when creating working robowaifus. I went down many different bunny trails and (often) fruitless paths of exploration. In the end I've finally hit on a relatively simplistic approach that AFAICT will actually allow us to both have the great flexibility we'll be needing, and without adding undue overhead and complexity. I call this the RW Foundations library, and I believe it's going to help us all out a lot with creating workable & efficient software that (very hopefully) will allow us to do many things for our robowaifus using only low-end, commodity hardware like the various single-board computers (SBCs) and microcontrollers. Devices like the Beaglebone Blue and Arduino Nano for example. Of course, we likely will also need more powerful machines for some tasks as well. But again, hopefully, the RW Foundations approach will integrate smoothly with that need as well and allow our robowaifus to smoothly interoperate with external computing and other resources. I suppose time will tell. So, to commemorate /robowaifu/'s 5th birthday this weekend, I've prepared a little demonstration project called Sumomo. The near-term goal for the project is simply to create a cute little animated avatar system that allows the characters Sumomo and Kotoko (from the Chobits anime series) to run around having fun and interacting with Anon. But this is also a serious effort, and the intent is to begin fleshing out the real-world robotics needs during the development of this project. Think of it kind of like a kickstarter for real-world robowaifus in the end, but one that's a very gradual effort toward that goal and a little fun along the way. I'll use this thread as a devblog and perhaps also a bit of a debate and training forum for the many issues we all encounter, and how a cute little fairybot/moebot pair can help us all solve a few of them. Anyway, happy birthday /robowaifu/ I love you guys! Here is my little birthday present to you. === >rw_sumomo-v211124.tar.xz.sha256sum 8fceec2958ee75d3c7a33742af134670d0a7349e5da4d83487eb34a2c9f1d4ac *rw_sumomo-v211124.tar.xz >backup drop

>>33843 >Blender does a lot of relevant things to support high performance, hard and soft realtime requirements, and heterogeneous development. Not sure what you mean about realtime in Blender's case, but otherwise fair enough. It's a remarkable system today! :^) >Blender's design docs I've seen these in the past, but since I stopped actively building Blender 2-3 years ago, I kind of let it slip my mind. So thanks for the reminder. I personally like Blender's documentation efforts, though I've heard some disagree. Not-uncommonly, this is one of those tasks that get pushed to the 'back burner', and is often left to volunteer work to accomplish. Given the breadth & scope of the platform, I'd say the Blender Foundation has done a yeoman's job at the doco work, overall. Very passable. <---> Also, reading that link reminded me of USD. NVIDIA is currently offering developers their version of free training on this topic, and I've been pondering if I can make the time to attend. A huge amount of the DCC industry has come together to cooperate on Pixar's little baby, and today it's a big, sprawling system. Why it's of interest to us here is that most of what a robowaifu will need to do to analyze and construct models of her 'world' is already accounted for inside this system. While there are plenty of other (often higher-speed) ways to accomplish the same (or nearly the same) tasks, the fact that USD has become such a juggernaut, with a highly-regimented approach to scene descriptions, and with such broad approval, improves the likelihood IMO that other Anons from the film & related industries may in fact be able to help us here once they discover robowaifus in the future -- if we're already using USD to describe her world and the things within it. I hope all that made sense, Anon. https://openusd.org/release/glossary.html# >===

>>33845 >Not sure what you mean about realtime in Blender's case This page looks relevant: https://developer.blender.org/docs/features/cycles/render_scheduling/ Blender does progressive rendering, which starts by rendering low-resolution frames. If there's extra time left over before a frame needs to be rendered, it generates more samples to generate a higher-resolution frame. The equivalent for video generation at a fixed framerate would be running a small number of denoising steps for the next frame, and running additional denoising steps if the next frame doesn't need to be rendered yet. For text generation at a fixed token rate, it would be equivalent to doing speculative decoding for the initial response, then using (maybe progressively) larger models if the next token doesn't need to be output yet. For a cognitive architecture with a fixed response rate, I think the equivalent would be generating an initial response, then continually refining the response based on self-evaluations & feedback from other modules until the the response needs to be output. >USD Very nice. I hadn't heard of this. It looks like a goldmine of information. Your explanation does make sense, and it's a great example of the sort of design patterns that I expect would be useful, in this case for modeling the environment & context.
>>33850 OK good point, CyberPonk. Such UX optimizations can fairly be said to be in the domain of soft-realtime. And certainly, integrating GPU processing code into the system to speed the rendering processes of Cycles & EEVEE has had major positive impacts. I personally think the fact that Ton chose to create the entire GUI for Blender in OpenGL all those years ago has had many far-reaching effects, not the least of which is general responsiveness of the system overall (especially as it has rapidly grown in complexity over the last few years). <---> >It looks like a goldmine of information Glad you like it! It's fairly easy to overlook that describing a scene is in fact a very-complex, nuanced, and -- I'm going to say it -- human undertaking. And when you consider that task from the deeply-technical aspect that USD (and we here) need to accommodate, then you wind up with quite a myriad of seeming-odd-juxtapositions. Until D*sney got their claws into it, Pixar was a one-of-a-kind studio, and well up to such a complicated engineering effort. I doubt they could do it as well today. If at all.

Beginners guide to AI, ML, DL. Beginner Anon 11/10/2020 (Tue) 07:12:47 No.6560 [Reply] [Last]
I already know we have a thread dedicated to books,videos,tutorials etc. But there are a lot of resources there and as a beginner it is pretty confusing to find the correct route to learn ML/DL advanced enough to be able contribute robowaifu project. That is why I thought we would need a thread like this. Assuming that I only have basic programming in python, dedication, love for robowaifus but no maths, no statistics, no physics, no college education how can I get advanced enough to create AI waifus? I need a complete pathway directing me to my aim. I've seen that some of you guys recommended books about reinforcement learning and some general books but can I really learn enough by just reading them? AI is a huge field so it's pretty easy to get lost. What I did so far was to buy a non-english great book about AI, philosophycal discussions of it, general algorithms, problem solving techniques, history of it, limitations, gaming theories... But it's not a technical book. Because of that I also bought a few courses on this website called Udemy. They are about either Machine Learning or Deep Learning. I am hoping to learn basic algorithms through those books but because I don't have maths it is sometimes hard to understand the concept. For example even when learning linear regression, it is easy to use a python library but can't understand how it exactly works because of the lack of Calculus I have. Because of that issue I have hard time understanding algorithms. >>5818 >>6550 Can those anons please help me? Which resources should I use in order to be able to produce robowaifus? If possible, you can even create a list of books/courses I need to follow one by one to be able to achieve that aim of mine. If not, I can send you the resources I got and you can help me to put those in an order. I also need some guide about maths as you can tell. Yesterday after deciding and promising myself that I will give whatever it takes to build robowaifus I bought 3 courses about linear alg, calculus, stats but I'm not really good at them. I am waiting for your answers anons, thanks a lot!

>>33765 > But I could see training one to recognize voice, one to deal with movement, one to deal with vision, specifically not running into things, and maybe one for instruction on a low level. Like move here, pick up this, etc If I remember right Mark Tilden referred to this as "horse and rider" setup, where you have a high level program giving direction to a lower level program. The lower level worries about not stepping in a hole, etc while the high level worries about where the pair are going. I too have experienced the boons of separating different functions into different programs/AI. To give a real life example of what you're talking about: my voice recognition AI doesn't like to run in the same program as the image recognition AI. I've experienced some programs running at different speeds, eg: on a raspi takes half a second for the image recognition to run, while the servo program can run like 2 dozen times a second while it is running, and the voice detection pauses the program until words are heard (or a 5 second timeout), so these different speeds/natures of the code requires separation, which in turn requires developing a way to communicate with each each program. >>33746 >Starting Best way to start is looking for a code/library that does what you want (like image recognition), and try tweaking it to fit your needs, like making it interact with other programs eg if an object is recognized in an image, move a servo.
>>33767 >I've experienced some programs running at different speeds Asynchrony is a deep topic in systems engineering for complex 'systems-of-systems' -- which full-blown robowaifus will certainly be in the end. The buffering and test, test, test combo has been the most successful engineering approach to this issue thus far, AFAICT. Just imagine the timing difficulties that had to be surmounted by the men who created and operated the Apollo spacecraft out to the Moon & back! Lol, our problems here are actually much more complicated (by at least a couple orders magnitude)!! :DD Kiwi discussed the desire that >A thread dedicated to man machine relationships may be needed : ( >>33634 ), and I agree. While my guess is that he meant for that thread to primarily be focused on the psychological/social aspects of those relationships, I would argue that the engineering of complex parts of our robowaifu's systems that in any way involve responsiveness or interaction-timing with her Master (or others) is definitely fair game for such a thread. The reason is simple: timing of interactions -- particularly verbal ones -- clearly affects the social perceptions of those (for all parties involved). >tl;dr < If it takes our robowaifus more than half a second to begin to respond to her Master's engagements, then we've waited too long...

Artificial Wombs general Robowaifu Technician 09/12/2019 (Thu) 03:11:54 No.157 [Reply] [Last]
I think we need to figure out how to fit a womb onto a waifubot. Where's the fun in having sex if you can't procreate?

Repost from a thread on /b/;
>"If you're like me and want to fuck a qt battlebot and get her pregnant, the best place to put an artificial womb is where a normal womb would be on a normal girl. The metal exterior could simply be a bunch of metal plates that unfold to allow space for the womb pod inside. The baby is probably safest inside the battlebot, and if she has good calibration then there shouldn't be problems with her falling and hurting the baby. After giving birth the metal plates could automatically fold back up again, shrinking the womb pod inside so she is combat effective again."

Well /robowaifu/? Feasible?

Modular Platform, "Assistant": Wheelchair-style robot base to jumpstart projects Lin 08/21/2023 (Mon) 01:14:26 No.24744 [Reply] [Last]
Lord knows I'm terrible at these writeups, so I'd recommend glancing at the attached CAD screenshots to get a quick idea of what this project is about-- on that note, most of this post will be copy/pasted stuff from the design docs, mainly stuff that won't change, so apologies in advance. Long story short, I've talked to a bunch of guys, both on the chans and elsewhere, who have some great ideas but aren't sure where/how to get started. My hope is that a (comparatively) simple, modular base that provides power, movement, and basic sensor data will let them get started on their own project without having to re-invent the wheel (and get nerd-sniped in the process.) # Brief The purpose of this platform is to establish a generalized "blueprint" of a (comparatively) cheap, human-scale "modular base platform" that can be built by a capable layman and maintained by a hobo, while supporting and powering any "robo payload" <= 75lbs, 5kW. Emphasis is placed on all parts being readily available or substitutable, and could conceivably be built from salvage at near zero cost (or in the face of malicious sales restriction), excepting digital controllers. Durability has also been prioritized, with over-engineered tolerances and (optional) bilateral redundancy for everything but the drive motors. Sacrifices have been made to accommodate this vision (primarily weight, though to a lesser extent, performance), and Builders with access to specialized tools or a higher budget will likely want to tweak the design (ex. using aluminum T-Slot instead of right-angle stock, welds in place of frame bolts, etc.) The design is purposefully made to resemble (and, if necessary, function as) a wheelchair (see reasoning below.) ## Project Budget Target Cost: $2,500 USD-2023 with new, mid-grade parts, excepting computer/processor. (realistically, I expect this to be closer to $3,500 in the short term, until people more clever than I improve some of the design's weaknesses/sacrifices) ## Prototype Info - Prototype Budget: $10,000 USD-2023 - (I have access to specialized equipment and labor (at a price), including a commercial 3D printer, 5-axis mill, welding, lifts, etc.) - First design revision expected by the new year (2024). Physical construction to begin Spring 2024. Basic electronic control system, motor/BMS interface to be somewhat complete between January and (Spring) 2024.

Been a while, my brothers-in-/robowaifu/. As anyone could have predicted, my team’s responsibilities didn’t end as cleanly as our calendar promised, but it’s “within epsilon” and I’ll have a decent amount of free time again starting from this weekend. Other than that, I managed to do a decent amount of physical design testing during the last couple months, which did lead to a few mechanisms being tweaked and one in the process of being redesigned (details next post) Anyway, part orders were delayed a bit-- there’s a few funny stories there, but it boils down to my being spoiled by having access to an ordering department/personnel... I have a newfound appreciation for all they do, let me tell you. Ended up automating most of what I could, which (hopefully) will make ordering less painful in the future. Hoping to get raw material stock (to which I didn’t attach part numbers during design) ordered mid-month. TL;DR: The last major part order should be placed the next week or two? I’ll have an hour or two on weekdays to work on my robot, but... I also have a lot of learning to do when it comes to machining, so I’ve ordered a decent amount of spare stock for when I inevitably screw something up. (another post coming later today or tomorrow detailing design changes) Also, going forward, my posts regarding solo projects will be a lot less detailed unless someone has specific questions/input (anyone here is free to ask, of course.) No deeper reason-- since I’m strapped for time, it’s just a lot more fun to spend my free time designing stuff than talking about it.

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. >tl;dr Post SE and Integration resources ITT. www.nasa.gov/sites/default/files/atoms/files/nasa_systems_engineering_handbook.pdf https://www.nasa.gov/reference/systems-engineering-handbook/ https://www.nasa.gov/reference/system-engineering-handbook-appendix/ >=== -patch dead hotlink

Namely; >how we can both take advantage of technical debt, and also remediate it ('pay it back') in our works too.
Just storing this here as a sober warning against mediocrity [1], when devising exceptionally-complex systems such as capable & pleasing robowaifus; they must operate continuously, safely & reliably in the near-presence of their Masters and other humans -- but component failures are inevitable. To wit: Failure of individual subsystem(s) in such a highly-interconnected system can rapidly cascade in unforeseen ways; the outcome of which may become catastrophic. <---> >"...To understand why, one must understand the concept of a “normal accident.” In 1984, Charles Perrow, a Yale sociologist, published the book, Normal Accidents: Living With High-Risk Technologies. In this book, Perrow lays out the theory of normal accidents: when you have systems that are both complex and tightly coupled, catastrophic failures are unavoidable and cannot simply be designed around. In this context, a complex system is one that has many components that all need to interact in a specified way to produce the desired outcome. Complex systems often have relationships that are nonlinear and contain feedback loops. Tightly-coupled systems are those whose components need to move together precisely or in a precise sequence." >( related : >>4631 ) --- 1. https://www.palladiummag.com/2023/06/01/complex-systems-wont-survive-the-competence-crisis/ >=== -sp, fmt, prose edit -add crosslink
