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 those who want animu grills IRL. Most robots have uncanny 3DPD faces that aren't nearly as cute as a real 2D waifu. With flat designs/screens, the face can keep the purity and beauty of 2D. There's still heaps of potential for producing low cost robots by reducing mass, power requirements, & simplifying design.

DARPA Wants Brain Implants That Record From 1 Million Neurons

The original thread can be found here: https://trashchan.xyz/robowaifu/thread/595.html --- Welcome to the Lemon Cookie thread, The goal of Lemon Cookie is to create a framework where a synthetic "mind and soul" can emerge through a "LLM as cognitive architecture" approach. This thread exists to collect feedback, ask for help & to document my progress. First I am going to try to give a high level overview of how this cognitive architecture is envisioned and the ideas behind it. I have spent time looking at cognitive architecture work, in the field there is now a consensus on how the mind works at a high level. An important mechanism is a "whiteboard", basically a global temporary memory that all the other systems read in and out of. Then there is different long-term memory systems that react to and add content to the whiteboard. Along with memory pattern matcher(s)/rules work on the content of the whiteboard. A key thing to consider is the difference in philosophy that cognitive architecture projects have, the intelligence is considered to emerge from the entire system. Compare this to LLM agent work where it's considered the intelligence is the LLM. My feelings on the general LLM space are conflicted, I am both amazed and really disappointed. LLMs possess an incredible level of flexibility, world knowledge and coherence. But everything outside of the model is stagnant. It's endless API wrappers & redundant frameworks all slight permutations on RAG & basic tool calling. I will believe that LLMs are misused as chatbots, simply put their pattern matching and associative power is constrained by chat format and shallow tooling. In the Lemon Cookie Cognitive Architecture so far here are the important aspects: 1. Memory is difficult. I do not think there is a singular data structure or method that is able to handle it all, several distinct types of memory will be needed. So far I plan for a PathRAG like system and a "Triadic Memory" inspired system for external associations (this is missing in most LLM solutions). 2. LLM as Kernel, The LLM's context window is the Whiteboard and has a REPL like mechanism. It holds structured data and logic in scripting-like format so it's both LLM & Human readable while staying easy to parse & allows for expressive structured data. The LLM's role will be to decompose data and make patterns and associations explicit as executable statements. 3. The language has to be LLM/CogArch-centric. There is a thousand ""agents"" that give LLMs a python interpreter as a tool. The two need to be more tightly coupled. Scripted behavior via pattern matching, The whiteboard is a bag of objects, this allows for programmable pattern matching (think functional programming like Haskell). It's also important to allow the LLM to observe code execution and to be able to modify state and execution flow. Data in languages have scoping rules, so should LLM context. Etc... I will go into more depth about the language in another post. 4. Another important system is the "GSR" Generative Sparse Representation and it will be a first class language & runtime type, This also needs its own post. But in general I am inspired by two things, "Generative FrameNet" paper where an LLM & an embedding model is used to automatically construct new FrameNet frames. The second source is "Numenta's SDRs"/"Sparse distributed memory" this representation has a lot of useful properties for memory (Please watch the videos under the "What the hell is an SDR?" segment in my links list for an easy introduction.) I think SDR unions & SDR noise tolerance will be especially useful. 5. A custom model, For all of the above to work well, a model will need to be fine tuned with special behaviors. I do want input on this. Baking facts & behaviors into LLM weights is costly, creating bloated models that are hard to run or train (why memorize all the capitals?), while letting authors gatekeep truth and impose "safety" detached from context. Blocking role-play "violence" or intimacy isn't protection: it's authors hijacking your AI companion to preach at you. Externalizing behaviors via whiteboard pattern matching shifts control: stabbing you in-game can be funny, but a robot wielding a knife isn't. Maybe you want intimacy privately, but don't want your AI flirting back at your friends. When put together I think this will be able to host a kind of synthetic "soul", In a living being what we call a personality is the accumulated associations, learned behaviors, beliefs and quirks molded by a unique set of experiences. I hope this will be true for this system too.

if you're wondering what this is, it's basically desktop pet but i'm the pet. (not going to be writing a formal project description for this, so i'm copying and pasting what i said from another thread starting from >>43828) antimaid will be an incredibly context-aware accountability partner who helps me be productive because i'm adhd as fuck. i need something to externalize executive function that isn't another person, a rigid schedule, or a job. instead it will be my robot daughter with system-level permissions and web browser integration. with this project, i've been toying around with the concept of "antimaid" that is pro-autonomy rather than pro-automation. name-wise, it's sort of like "antivirus." basically it's an assistant that opposes learned helplessness. it makes users better at managing tasks in ways that don't make users functionally dependent on it to accomplish these tasks. without it, users are still fully capable of doing what it helped the users with, but may do it less consistently without the structure it provided. many people already have structures like these in the form of jobs that must be physically commuted to. but people who are working remotely/self-employed/unemployed and/or neurodivergent may not benefit as much from existing structures.

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. >=== -tmp locked to dissuade derailling

>"And as you wish that others would do to you, do so to them."[1] >-t. Jesus Christ I propose this thread to be a narrowly-scoped discussion on the OP's topic; informed primarily by 2 Christian-themed writings, and by our own efforts & practical insights in developing robowaifus : I. In Mere Christianity, C.S. Lewis asserts that all men "...have the Law of God written on their hearts."[2][3][4] This is certainly affirmed by various passages in the Holy Scriptures, as well. II. In The City of God, Aurelius Augustine of Hippo writes >"And yet they have within themselves something which they could not see: they represented to themselves inwardly things which they had seen without, even when they were not seeing them, but only thinking of them. But this representation in thought is no longer a body, but only the similitude of a body; and that faculty of the mind by which this similitude of a body is seen is neither a body nor the similitude of a body; and the faculty which judges whether the representation is beautiful or ugly is without doubt superior to the object judged of. >"This principle is the understanding of man, the rational soul; and it is certainly not a body, since that similitude of a body which it beholds and judges of is itself not a body. The soul is neither earth, nor water, nor air, nor fire, of which four bodies, called the four elements, we see that this world is composed. And if the soul is not a body, how should God, its Creator, be a body?[5][6][7] Now, starting from the fundamental basis & belief (a priori w/ no defenses given pertaining to it >tl;dr let's not descend into debate on this point, merely discuss the implications of it, kthx :^) that this immaterial, moral law inscribed on each of our hearts by God literally serves as the foundational stone for all good ethics & all good moralities out there; I'd like for us all lurkers, I'm looking at you! :^) to have a general discussion on: A) What does this all imply (and likely mean) regarding human behaviours within the general cultural/societal domain under discussion, and

(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!
