This is a rather important project for the people involved here. I just had this amazing idea, which allows us to catalogue and make any of the information here searchable in a unique way. It functions very similarly to an image booru, but for markdown formatted text. It embeds links and the like. We can really make this thing our own, and put the entire board into a format that is indestructible. Anyone want to help build this into something great? I'll be working on this all day if you want to view the progress on GitHub. https://github.com/SoaringMoon/WaifuNetwork

Selecting a Programming Language Robowaifu Technician 09/11/2019 (Wed) 13:07:45 No.128 [Reply] [Last]
What programming language would suit us and our waifus best? For those of us with limited experience programming, it's a daunting question.
Would a language with a rigid structure be best?
Do we want an object-oriented language?
How much do you care about wether or not a given language is commonly used and widespread?
What the fuck does all that terminology mean?
Is LISP just a meme, or will it save us all?

In this thread, we will discuss these questions and more so those of us who aren't already settled into a language can find our way.

This is VERY COOL. A "Scratch" like visual programming for micro-controllers. ESP32 included. Has a multitasking OS using byte code. OS is 16k. Can run n a browser or downloaded program. Can be used to test programs in a virtual micro-controller on the web or, I think, built in the program. http://microblocks.fun/ I've been reading a lot of Alan Kay's stuff so this makes sense.
>>26245 Okay. Not sure how much one could do with that and if it was suitable for doing something related to robowaifus, but it might come in handy.
>>26245 Neat! Thanks Grommet (good to see you BTW). I love Scratch, and think it's kind of visual interface will be highly valuable as a scripting interface for us, once robowaifus have become commonplace enough for Joe Sixpack's to be clammoring for their own.

https://www.nature.com/articles/s41586-023-06484-9 >DNA-based programmable gate arrays for general-purpose DNA computing >The past decades have witnessed the evolution of electronic and photonic integrated circuits, from application specific to programmable1,2. Although liquid-phase DNA circuitry holds the potential for massive parallelism in the encoding and execution of algorithms3,4, the development of general-purpose DNA integrated circuits (DICs) has yet to be explored. Here we demonstrate a DIC system by integration of multilayer DNA-based programmable gate arrays (DPGAs). We find that the use of generic single-stranded oligonucleotides as a uniform transmission signal can reliably integrate large-scale DICs with minimal leakage and high fidelity for general-purpose computing. Reconfiguration of a single DPGA with 24 addressable dual-rail gates can be programmed with wiring instructions to implement over 100 billion distinct circuits. Furthermore, to control the intrinsically random collision of molecules, we designed DNA origami registers to provide the directionality for asynchronous execution of cascaded DPGAs. We exemplify this by a quadratic equation-solving DIC assembled with three layers of cascade DPGAs comprising 30 logic gates with around 500 DNA strands. We further show that integration of a DPGA with an analog-to-digital converter can classify disease-related microRNAs. The ability to integrate large-scale DPGA networks without apparent signal attenuation marks a key step towards general-purpose DNA computing.

Lab grown organic animal cells are still in their infancy stages with a lot of regulations and moral/ethical concerns impeding further development. I'm all for it as i'm an anarcho capitalist, but there are too many factors at play right now regarding that stuff. Alginic hydrogel is more than appropriate for making soft muscle actuators and other body parts for gynoids. Not to mention how well it is with being anti-microbial. What we do with this approach wil act as a stepping stone for further development inching us toward our goal of fixing the woman problem. My idea has a lot of holes as all of the others do regarding fabrication and lack of adequate R&D, but it'll just have to sit on the shelf for now with all of the other grandiose things I've thought up. I have more important matters to tend to for now. My primary concern is with the advent of government creeping into every facet of normal life. This will also affect any robot wife progress that could happen in the foreseeable future.

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.

I was working on this here >>26112 using OpenCL to make video processing faster. So I got this here recommended by YouTube: https://www.youtu.be/0Kgm_aLunAo Github: https://github.com/jjmlovesgit/pipcounter This is using OpenCV to count pips on dominos, and does it much faster and better than GPT4-Vision. I wonder if it would be possible to have a LLM adjust the code dependent on the use case, and maybe having a library of common patterns to look out for. Ideally one would show it something new, it would detect the outer border like the stones here and then adjust till it can catch the details on all of these objects which are of interest. It could look out for patterns dependent on some context, like e.g. a desk.
>>26132 >and does it much faster and better than GPT4-Vision. Doesn't really surprise me. OpenCV is roughly the SoA in hand-written C++ code for computer vision. You have some great posts ITT Anon thanks... keep up the good work! :^)
There are several libraries and approaches that attempt to achieve generalized object detection within a context, although creating a completely automatic, context-based object detection system without predefining objects can be a complex task due to the variability of real-world scenarios. However, libraries and methodologies that have been utilized for more general object detection include: 1. YOLO (You Only Look Once): YOLO is a popular object detection system that doesn't require predefining objects in the training phase. It uses a single neural network to identify objects within an image and can detect multiple objects in real-time. However, it typically requires training on specific object categories. 2. OpenCV with Haar Cascades and HOG (Histogram of Oriented Gradients): OpenCV provides Haar cascades and HOG-based object detection methods. While not entirely context-based, they allow for object detection using predefined patterns and features. These methods can be more general but might not adapt well to various contexts without specific training or feature engineering. 3. TensorFlow Object Detection API: TensorFlow offers an object detection API that provides pre-trained models for various objects. While not entirely context-based, these models are designed to detect general objects and can be customized or fine-tuned for specific contexts. 4. Custom Object Detection Models with Transfer Learning: You could create a custom object detection model using transfer learning from a pre-trained model like Faster R-CNN, SSD, or Mask R-CNN. By fine-tuning on your own dataset, the model could adapt to specific contexts. 5. Generalized Shape Detection Algorithms: Libraries like scikit-image and skimage in Python provide various tools for general image processing and shape analysis, including contour detection, edge detection, and morphological operations. While not object-specific, they offer tools for identifying shapes within images. Each of these methods has its advantages and limitations when it comes to general object detection. If you're looking for a more context-aware system that learns and adapts to various contexts, combining traditional computer vision methods with machine learning models trained on diverse images may be a step towards achieving a more generalized object detection system. However, creating a fully context-aware, automatic object detection system that adapts to any arbitrary context without any predefined objects is still a challenging area of research. -----------------

>>26146 Understood. If the goal is to identify various objects within a specific context (like a desk) without predefining the objects, and the lighting conditions might vary, a more flexible approach using general computer vision techniques can be applied. This could involve methods such as contour detection, edge detection, and basic image processing techniques to identify objects within the context of a desk. You might use a more generalized version of object detection that isn’t specific to particular objects but rather identifies any distinguishable shape within the context. Here’s an example: python import cv2 # Read the image image = cv2.imread('path_to_your_image.jpg') # Convert to grayscale gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY) # Apply thresholding or other preprocessing techniques to enhance object edges # ...

Good VR is one important interim goal for a fully-realized RoboWaifu, and it's also much easier to visualize an algorithm graphically at a glance than 'trying to second-guess a mathematical function'. OpenGL is by far the most portable approach to graphics atm.

>"This is an excellent site for starting with OpenGL from scratch. It covers from very introductory topics all the way to advanced topics like Deferred Shading. Liberal usage of accompanying images and code. Strongly recommended."

Unrelated: Does the system redraw from the bottom-up? For some reason I thought the drawing happened from the upper-left corner down, but apparently not. Given that the coordinate origin for the system starts in the lower-left corner (similar to a Cartesian system) I guess that makes sense. Live and learn.
>>26098 This here about the Lobster language is related to OpenGL. This is why it is fast, I don't think that it is compiled is much important for speed, though it might have other advantages. For now I'm trying to use Python with OpenGL to do the same thing. Not to confused with OpenCL which I also need to use. I found the term "delta compression" for calculating differences in frames. I hope I can make the animations smaller that way. My current way of "programming" this is asking ChatGPT for every step while learning about how it works. With basic knowledge of Python it works relatively well, even with GPT-3. I'm getting the terms I need to look for how to do things, and the code which needs some polishing.

>>26108 Okay, I fell into a rabbit hole here. It was interesting, but probably useless. I rather need a collection of GIFs or so. I wondered why no one else had this idea before, I'm starting to understand where the problem is and why it might be hard or impossible. [quote] You are correct. In a delta compression approach where you keep the original frames and use delta frames to reconstruct, the primary advantage is not in reducing storage requirements but rather in potentially reducing the processing load when displaying or working with the frames in real-time. The advantage lies in the efficiency of processing and transmitting the frames, especially when dealing with limited computational resources or bandwidth. Here's a clearer explanation of the advantage: 1. Reduced Processing Load: By storing and transmitting only the delta frames, you can reduce the amount of data that needs to be processed, especially when displaying or working with the frames in real-time. Instead of working with full frames, you process the smaller delta frames, which can be computationally less intensive. 2. Real-Time Efficiency: In applications where real-time processing or streaming is crucial, delta compression can be advantageous. It allows for quicker decoding and display of frames, which is important in video conferencing, surveillance, and interactive applications. 3. Bandwidth Efficiency: When transmitting video data over a network, delta compression can reduce the required network bandwidth, making it feasible to stream video even with limited bandwidth. However, it's important to note that you still need the original frames to apply the delta frames and reconstruct the complete frames. The advantage is in processing efficiency, not in storage efficiency. You trade off storage efficiency for computational and bandwidth efficiency. If your priority is purely reducing storage requirements and you don't need real-time processing or streaming, then traditional video codecs that achieve high compression ratios while storing complete frames might be more suitable for your use case.[/quote]

/robowaifu/ + /all things monster girl/; it's benefits, projects, the uncanny valley, etc. Robowaifu Technician 05/03/2021 (Mon) 14:02:40 No.10259 [Reply] [Last]
Discussing the potential benefits of creating monster girls via robotics instead of 1 to 1 replicas of humans and what parts can be substituted to get them in production as soon as possible. Firstly is the fact that many of the animal parts that could be substituted for human one are much simpler to work with than the human appendages, which have a ton of bones and complex joints in the hands and feet, My primary example of this is bird/harpy species (image 1), which have relatively simple structures and much less complexity in the hands and feet. For example, the wings of the bird species typically only have around three or four joints total, compared to the twenty-seven in the human hand, while the legs typically only have two or three, compared to the thirty-three in the human foot. As you can guess, having to work with a tenth of the bones and joints and opposable thumbs and all that shit makes things incredibly easier to work with. And while I used bird species as an example, the same argument could be put forward for MG species with paws and other more simplistic appendages, such as Bogey (image 2) and insect hybrids (image 3). Secondly is intentionally making it appear to not be human in order to circumvent the uncanny valley. It's incredibly difficult to make completely convincing human movement, and one of the simplest ways around that is just to suspend the need for it entirely. We as humans are incredibly sensitive to the uncanny valley of our own species, even something as benign as a prosthetic limb can trigger it, but if we were to create something that we don't expect to move in such a way, it's theoretically entirely possible to just not have to deal with it (for the extremities part of it, anyways), leaving more time to focus on other aspects, such as the face. On the topic of face, so too could slight things be substituted there (again for instance, insect girls), in order to draw attention away from the uncanny valley until technology is advanced enough that said uncanny valley can be eliminated entirely. These possibilities, while certainly not to the taste of every anon, could be used as a way to accelerate production to the point that it picks up investors and begins to breed competition and innovation among people with wayyyyyyy more money and manpower than us, which I believe should be the endgoal for this board as a whole. . Any ideas or input is sincerely appreciated.

>>25856 >>26037 >Do the middle pairs of legs need to rotate? Yes they do. Under the category of missing the obvious- to go up and down stairs. Or negotiate slopes. The legs need to be able to assume a near-vertical orientation in their operation or side loads will cause damage, like trying to bend your knee in the wrong plane. So as our girl goes up stairs and her body changes orientation to match the slope of the stairs by up to 45 degrees to the horizontal, her legs need to rotate at the hip to be able to operate properly. So we are up to a minimum of 4 actuators per each leg with 3 leg segments. >>26037 >Leg rotation relative to hips have front and back sets of legs on a pivot controlled by a worm drive to limit back driving That would restrict independent movement of the legs. For example in a "hug" with the forelegs they would be at the same level and bang into each other, instead of being at slightly different levels, and our girl couldn't move them up and down separately to rub *or "grope"* anon. If the rear legs can be made to tie knots they will need to be independently moveable. The middle pair of legs may be able to use this for adjusting their angle for slopes and stairs. The problem then is not being able to easily remove one leg for repair. Removable as opposing pairs? Then we would need more types of spares. >>26034 >Batteries and CG This also relates to the placement of the legs. I am thinking of a finished spider-girl with right legs, but she would be able to walk (but not much else) with 4 or 6. So build her with 8 leg mounts and start with 4 and add the rest as time, money or code development permits. With 6 legs you could have the first two leg pairs and the rearmost pair to start. The 2nd and 4th pair could be set in position (like the hydraulic legs of heavy equipment) to allow for elevated use of the front pair. For this we might want the CG to be rearward in the thorax. If we wanted to use the rear legs for web-spinning, we would set the first and 3rd pair legs with the CG more forward in the thorax. We would need to choose which arrangement is more desirable until we have all eight legs.
>>25707 >>26014 > The conclusion I came to was that you’d need at least 5 separate contractile regions, all independently addressable, AND able to contract dY for the snake-bot to be capable of any generalized sort of locomotion. Yes, that's just what the design I described should do. By having the cable winches attached to several disc vertebrae down-body from each winch, the overlap of each set of cables emulates the overlap of muscles in a snake's body. In this way the contraction of each set of cables can be individually controlled to either stand alone or gang together over a distance of several vertebrae, and the size of each "muscle" group (and therefore the number of muscle groups) can be varied on the fly by the controlling code. The operation of the cable winch groups can be done in sequence along the body to emulate the sinuous movement of a snake, and the winch-and-cable sets in the vertical plane for coiling the body can be used to adjust the areas of contact with the surface the body is moving over. To be clear, each vertebra is attached to several winches by cables, and can be acted upon by one or any number of the cables attached to it. The force of each winch is spread over several vertebrae, but several winches acting on each vertebrae combine to increase the force applied. By varying the spacing of the vertebrae discs, the diameter of each vertebrae disc, vs the diameter of the foam body and the resiliency of the foam used for the body (say 8" dia. vertebrae spaced 6" and 12" body dia.), it should be possible for the coils to be as tight as a few inches. With a larger sized object, like anon's body, our lamia should have no problem exerting a firm grip. As with an arachne, anon should probably have a safe word. Something I didn't think of before, real snakes are able to do a twisting motion with at least the forward part of their bodies, so we may also want to copy that. The 18" body size I mentioned before was at the "hip" area before the tapering of the snake body. I should have made that clear. >https://pubmed.ncbi.nlm.nih.gov/32271916/ (source analysis) >https://pubmed.ncbi.nlm.nih.gov/36296136/ (proposed robotic design based on analysis) Thanks, I'll take a look at these when I have a chance. >===

>>25838 >find out how many legs of a spider are off the ground at one time as it is moving At most four. There are always at least 4 on the ground at any time in the walking cycle. So each of our spider-girl's legs must be able to support 1/4 of her total weight, plus whatever extra we decide on for contingencies. That could be 1/3 of the total weight (maybe a little more?), in case one leg is disabled, so she could still safely walk to her service area (if the code isn't smart enough to adapt to a broken leg). Or if you are feeling particularly ambitious you might want her strong enough to carry her own weight plus anon's weight (plus excess safety margin) for when she needs to carry anon somewhere after demonstrating her web-spinning. In that case only four legs might be walking so 3 on the ground at all times, a quadruped. Here's a site with a good description of how spider legs work: Leg Uses Hydraulics and Muscle Flex https://asknature.org/strategy/leg-uses-hydraulics-and-muscle-flex/ Here's a paper on soft robotic spider legs cited on the website^.

Not sure how difficult it would be with servos w/o some dissassembly but with electrical motors regardless of type you can closely aproximate their % load by how much current they draw relative to max allowed which should not be difficult to track via analog inputs. Some simple algorithm would then calculate how many legs may be in air at any time and how far can legs neighbouring strained limb move to offset its load.

What would be a good RW simulator. I guess I'd like to start with some type of PCG solution that just builds environments to start with and build from there up to characters.

It would be nice if the system wasn't just pre-canned, hard-coded assets and behaviors but was instead a true simulator system. EG, write robotics control software code that can actually calculate mechanics, kinematics, collisions, etc., and have that work correctly inside the basic simulation framework first with an eye to eventually integrating it into IRL Robowaifu mechatronic systems with little modifications. Sort of like the OpenAI Gym concept but for waifubots.
