(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!

Material Science & Production This thread is dedicated to all aspects of material sciences in robotics. This includes production methods for creation, processing, and manipulating materials to attain desired results. Our future robowaifus must be built using materials we can attain and sculpt into them. Let's work together to build the future. Consider picrel, what materials would you use for her shell? Her skeleton? Consider mechanical properties, density, how they would feel to hold. All are important aspects we must consider. This thread will have overlap with the 3D printing thread. Feel free to crosslink at will. This thread is made as a merger of 2 previous material threads and a CNC thread.

Post about whatever media predominately features at least one fembot aka gynoid (female form of an android) as an important character, ideally a robowaifu or synthetic girlfriend. Some freedom with the topic is allowed, virtual waifus or bodiless AI might also qualify if she is female. Negative framing of the whole topic should be mentioned with negative sentiment. Cyborgs with a human brain or uploads of women don't really fit in, but if she's very nice (Alita) and maybe not a human based cyborg (catborg/netoborg) we can let it slide. Magical dolls have also been included in the past, especially when the guy had to hand-made them. Look through the old thread, it's worth it: >>82 - Picrel shows some of the more well know shows from a few years ago. I made a long list with links to more info's on most known anime shows about fembots/robowaifus, without hentai but including some ecchi and posted it here in the old thread: >>7008 - It also features some live-action shows and movies. I repost the updated list here, not claiming that it is complete, especially when it comes to live action and shows/movies we don't really like. >In some cases I can only assume that the show includes robogirls, since the show is about various robots, but I haven't seen it yet.

OpenAI/GPT-2 This has to be one of the biggest breakthroughs in deep learning and AI so far. It's extremely skilled in developing coherent humanlike responses that make sense and I believe it has massive potential, it also never gives the same answer twice. >GPT-2 generates synthetic text samples in response to the model being primed with an arbitrary input. The model is chameleon-like—it adapts to the style and content of the conditioning text. This allows the user to generate realistic and coherent continuations about a topic of their choosing >GPT-2 displays a broad set of capabilities, including the ability to generate conditional synthetic text samples of unprecedented quality, where we prime the model with an input and have it generate a lengthy continuation. In addition, GPT-2 outperforms other language models trained on specific domains (like Wikipedia, news, or books) without needing to use these domain-specific training datasets. Also the current public model shown here only uses 345 million parameters, the "full" AI (which has over 4x as many parameters) is being witheld from the public because of it's "Potential for abuse". That is to say the full model is so proficient in mimicking human communication that it could be abused to create new articles, posts, advertisements, even books; and nobody would be be able to tell that there was a bot behind it all. <AI demo: talktotransformer.com/ <Other Links: github.com/openai/gpt-2 openai.com/blog/better-language-models/ huggingface.co/

Creating robowaifus requires lots and lots of design and artistry. It's not all just nerd stuff you know Anon! :^) ITT: Add any techniques, tips, tricks, or content links for any Digital Content Creation (DCC) tools and training to use when making robowaifus. >note: This isn't the 'Post Your Robowaifu-related OC Arts & Designs General' thread. We'll make one of those later perhaps. >--- I spent some time playing with the program Makehuman and I'll say I wasn't impressed. It's not possible to make anime real using Makehuman, in fact the options (for example eye size) are somewhat limited. But there's good news, don't worry! The creator of Makehuman went on to create a blender plugin called ManuelBastioniLAB which is much better (and has a much more humorous name). The plugin is easy to install and use (especially if you have a little blender experience). There are three different anime female defaults that are all pretty cute. (Pictured is a slightly modified Anime Female 2.) There are sliders to modify everything from finger length to eye position to boob size. It even has a posable skeleton. Unfortunately the anime models don't have inverse kinematic skeletons which are much easier to pose. Going forward I'm probably going to use MasturBationLABManuelBastioniLAB as the starting point for my designs. --- Saving everything with yt-dlp (>>16357, >>12247) >===

Tensegrity Thread Tenssegrity is the purposeful application of tension in a system of non-contact components to provide integrity. These components effectively float on compression provided by tension elements. Tensegrity structures are often formed via rigid rods with a cable defining the spatial relations of the system. Picrel 1 is NASA’s Super Ball Bot, which uses the common 6 bar structure. By altering the lengths of the rods, the “ball” can roll. Please see (https://www.nasa.gov/image-article/super-ball-bot/) Our bodies use tensegrity to provide us with incredible strength, durability, and adaptability. Consider how when you bump into something or fall, you can feel the pressure dissipate throughout large parts of your body. This is due to your muscles, fascia, ligaments, etc… transferring the force throughout your body, protecting the impacted part. You can walk with little effort thanks in part to tensegrity. Your legs joints are all floating, providing low friction movement while distributing the force of impact throughout your entire leg when you step. Please see (http://intensiondesigns.ca/geometry-of-anatomy/) Tensegrity can also be made with elastic elements. These structures are what I believe are best suited for our endeavors. They provide looser tolerance requirements and give her body some squeezability. By incorporating naturally stretchable elements, she can better withstand having an Anon using her. (I speak from experience, though I still broke that torso before taking pictures.) Though there are drawbacks. These designs are deceptively difficult to design correctly. Our requirements for external aesthetics provide unique design requirements that complicate the design phase. I still believe using this concept is objectively correct for us to pursue. A good example to build off of (Debatable whether or not it’s true tensegrity): https://www.thingiverse.com/thing:4182634

This thread is for discussion, warnings, tips & tricks all related to robowaifu privacy, safety & security. Or even just general computing safety, particularly if it's related to home networks/servers/other systems that our robowaifus will be interacting with in the home. --- > thread-related (>>1671) >=== -update OP -broaden thread subject -add crosslink

Post your prototypes and failures. We fail until we win. Don't forget looking through the old threads here >>418, >>18800 and >>21647 to understand how we got to where we are now.

For the most of 2024 and until now, I have been working on my own robowaifu design. I call her Galatea. The design is very easy to build with the instructions and files, and is relatively very cheap, less than $400 to make. It's also very customizable, you can choose the color, dress, hair, and even AI. I intend this to be the Model T of humanoid robots and robotic companions, while it is not the most complex, it is easy to mass produce and cheap. The updated design makes the legs more proportionate, and a new head that's more anime styled, to increase cuteness. I also have a new robot base that's more powerful.
