(1stl thread >>406 2nd thread >>12810) Kiwi back again with a thread for discussing actuators to move your waifu! Part Three! Let's start with a quick introduction to common actuators! 1. DC motors, these use brushes to switch the ferrous core electromagnets on a rotor to rotate its magnetic field relative to surrounding magnets! They're one of the cheapest options with an average efficiency range of 30 to 90%. Larger DC motors and motors with higher turn counts are more efficient. 1.5 Coreless DC motors, by removing ferrous materials, losses from hysteresis are almost eliminated, dramatically increasing efficiency to nearly 90% even in small motors. Eliminating the ferrous materials reduces flux focusing, resulting in weaker fields and higher speeds. 2. Brushless DC motors (BLDC), these use a controller to switch the electromagnets on a stator to rotate the magnets of a rotor! Without brushes, they have the potential to be more efficient with higher power density compared to DC motors. Their efficiency and behavior vary depending on the algorithm and sensors used to control them. Coreless brushless motors exist but are rare and only used for very niche applications. 3. AC motors, a wide and incredibly varied category. They all rely on AC’s frequency to control them. With single phase AC motors relying on shaded poles, capacitors, or some other method to induce a rotating magnetic field. 3 phase AC motors naturally have a rotating field which usually gives them higher efficiency and power density. Notably, most AC motors are brushless. The most commonly used brushed AC motor is the universal motor, which is 4. Stepper motors, brushless motors with ferrous teeth to focus magnetic flux. This allows for incredible control (stepping) at the cost of greater mass, subsequently giving them higher rotary inertia. Usually 50 to 80% efficient depending on control algorithm/speed/and quality of the stepper. Due to their increasing mass production (& ubiquitous low cost controllers), they have appeal as a lower cost alternative to BLDC motors if one carefully designs around them. 5. Coiled Nylon Actuators! These things have an efficiency rating so low it's best to just say they aren't efficient. (0.01% typical, 2% achieved under extremely specific conditions in a lab.) Though they are exciting due to their incredible low cost of fabrication, they’re far too slow and the energy requirements are nonsensical. https://youtu.be/S4-3_DnKE9E https://youtu.be/wltLEzQnznM 6. Hydraulics! These rely on the distribution of pressure in a working liquid to move things like pistons. Though popular in large scale industry, their ability to be used in waifu's has yet to be proven. (Boston Dynamics Atlas runs on hydraulics but it's a power guzzler and heavy) Efficiency varies wildly depending on implementation. They would work great for a giantess! 7. Pneumatics, hydraulics lighter sister! This time the fluid is air! This has the advantage in weight. They aren't capable of the same power loads hydraulics are but, who wants their waifu to bench press a car? (Too loud and inefficient for mobile robotics.) 8. Wax motors, hydraulic systems where the working fluid is expanding melted (commonly paraffin) wax! Cheap, low power, and produce incredible forces! Too bad they're slow and hard to control. 9. Explosion! Yes, you can move things through explosions! Gas engines work through explosions! Artificial muscles can be made by exploding a hydrogen and oxygen mixture in a piston, then using hydrolysis to turn the water back into hydrogen and oxygen. None of this is efficient or practical but it's vital we keep our minds open! Though there are more actuators, most are derivatives or use these examples to work. Things like pulleys need an actuator to move them. Now, let's share, learn, and get our waifu moving!

Would you walk around with your waifu? Would you hold her in public? Would you shamelessly have her custody with you to conventions? Would you take her on dates? This thread is for discussing how you'd interact with your waifu outside of the home.

That Time I Incarnated My Christian Cat Girl Maid Wife in a Short Dress Together we can create the robowaifu-verse! Let's start making media to further our cause. There's tremendous potential for us to reach a wide market and prime minds to accept their future cat grill meidos in tiny miniskirts. We have text based stories floating around but, audio and visuals are paramount to gain a general audience. I will start with a short about a young man building a small cat girl and learning to understand her love. Importantly, she will be very limited, in the same way our first models will be. To set certain expectations. Mahoro is impossible but, the slow and simple robowaifus that can exist have their own charm. Let's show the world the love that will soon exist. --- >thread-related Robowaifu Propaganda and Recruitment (>>2705) >=== -add related crosslink

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.

Scientists made a neural network from rat neurons that could fly a fighter jet in a simulator and control a small robot. I think that lab grown biological components would be a great way to go for some robowaifu systems. It could also make it feel more real. https://www.google.com/amp/s/singularityhub.com/2010/10/06/videos-of-robot-controlled-by-rat-brain-amazing-technology-still-moving-forward/amp/ >=== -add/rm notice

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

Anything in general related to the Robotics or A.I. industries, and any social or economic issues surrounding it (especially of robowaifus). -previous threads: > #1 (>>404) > #2 (>>16732) > #3 (>>21140)

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!

We need to talk about bipedal locomotion. It's a complicated topic but one that has to be solved if we are ever to have satisfyingly believable robowaifus. There has surely already been a lot of research done on this topic, and we need to start digging and find the info that's out there. There are some projects that have at least partial robolegs solutions working, but none that I know of that look very realistic yet. We likely won't come up with some master-stroke of genius and solve everyone's problems here on /robowaifu/, but we should at least take a whack at it who knows? We certainly can't accomplish anything if we don't try.

I personally believe we should be keeping the weight out of the extremities – including the legs – while other anons think that we should add weight to the feet for balance. What's you're ideas anon? How do we control the gait? How do we adjust for different conditions? What if our robowaifu is carrying things? What about the legs during sex? Should we focus on the maths behind MIP (Mobile Inverted Pendulum), or is there a different approach that would be more straightforward? A mixture? Maybe we can even do weird stuff like reverse-knee legs that so many animals have. Robofaun waifu anyone? What about having something like heelys or bigger wheels in the feet as well?

I'm pretty sure if we just put our heads together and don't stop trying, we'll eventually arrive at least one good general solution to the problem of creating bipedal robot legs.

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'
