Why Robowaifu? Most of the world's modern women have failed their men and their societies, feminism is rampant, and men around the world have been looking for a solution. History shows there are cultural and political solutions to this problem, but we believe that technology is the best way forward at present – specifically the technology of robotics. We are technologists, dreamers, hobbyists, geeks and robots looking forward to a day when any man can build the ideal companion he desires in his own home. However, not content to wait for the future; we are bringing that day forward. We are creating an active hobbyist scene of builders, programmers, artists, designers, and writers using the technology of today, not tomorrow. Join us!

We will need better sources and understanding to compare the more expensive SBCs. For example, the TOPS benchmark can be misleading. Also ... > "a decisive factor for many industrial applications is the long-term availability" ... High TOPS might also not be necessary, because of the limits of input data, like framerate of cameras. >Where a lot of TOPS are really needed is in “real-time critical” applications. Some SBC with a "i.MX 8M Plus"-based SBC might be well suited for robots at home, which also should have long term support. It also might have more support than more exotic NLUs (neural processing unit), because of a more widespread use, independent from the support of the company behind the SBC or NLU. >Excessive TOPS have no impact if the NPU is not supplied with enough data. >Do I Need an NPU? ... if there is a task that can be handled by “classic machine learning” (support vector machine, tree learner, …), the use of a CPU is sufficient in many cases.

For those still trying to use a Raspberry PI, here's a availability tracker: https://rpilocator.com/ - This is mostly as confirmation to use other alternatives, especially since we only need some server which might not even be (directly) connected to the internet.

AI Design principles and philosophy Robowaifu Technician 09/09/2019 (Mon) 06:44:15 No.27 [Reply] [Last]
My understanding of AI is somewhat limited, but personally I find the software end of things far more interesting than the hardware side. To me a robot that cannot realistically react or hold a conversation is little better than a realdoll or a dakimakura.

As such, this is a thread for understanding the basics of creating an AI that can communicate and react like a human. Some examples I can think of are:

ELIZA was one of the first chatbots, and was programmed to respond to specific cues with specific responses. For example, she would respond to "Hello" with "How are you". Although this is one of the most basic and intuitive ways to program a chat AI, it is limited in that every possible cue must have a response pre-programmed in. Besides being time-consuming, this makes the AI inflexible and unadaptive.

The invention of Cleverbot began with the novel idea to create a chatbot using the responses of human users. Cleverbot is able to learn cues and responses from the people who use it. While this makes Cleverbot a bit more intelligent than ELIZA, Cleverbot still has very stilted responses and is not able to hold a sensible conversation.

Taybot is the best chatbot I have ever seen and shows a remarkable degree of intelligence, being able to both learn from her users and respond in a meaningful manner. Taybot may even be able to understand the underlying principles of langauge and sentence construction, rather than simply responding to phrases in a rote fashion. Unfortunately, I am not sure how exactly Taybot was programmed or what principles she uses, and it was surely very time-intensive.

Which of these AI formats is most appealing? Which is most realistic for us to develop? Are there any other types you can think of? Please share these and any other AI discussion in this thread!

Why do tree-based models still outperform deep learning on typical tabular data? >Abstract: While deep learning has enabled tremendous progress on text and image datasets, its superiority on tabular data is not clear. We contribute extensive benchmarks of standard and novel deep learning methods as well as tree-based models such as XGBoost and Random Forests, across a large number of datasets and hyperparameter combinations. We define a standard set of 45 datasets from varied domains with clear characteristics of tabular data and a benchmarking methodology accounting for both fitting models and finding good hyperparameters. Results show that tree-based models remain state-of-the-art on medium-sized data (10K samples) even without accounting for their superior speed. To understand this gap, we conduct an empirical investigation into the differing inductive biases of tree-based models and neural networks. This leads to a series of challenges which should guide researchers aiming to build tabular-specific neural network: 1) be robust to uninformative features, 2) preserve the orientation of the data, and 3) be able to easily learn irregular functions. To stimulate research on tabular architectures, we contribute a standard benchmark and raw data for baselines: every point of a 20\,000 compute hours hyperparameter search for each learner. https://openreview.net/forum?id=Fp7__phQszn This could be very relevant for an AI assembled out of many parts.

But also claims wheeled robots like pepper wouldn't be good enough for that (which I rather question). He claims humans would want bipedal robots in many places, which might be kind of true but also dependent on many things like the price for example.

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.

Hand Development Robowaifu Technician 07/28/2020 (Tue) 04:43:19 No.4577 [Reply] [Last]
Since we have no thread for hands, I'm now opening one. Aside the AI, it might be the most difficult thing to archive. For now, we could at least collect and discuss some ideas about it. There's Will Cogleys channel: https://www.youtube.com/c/WillCogley - he's on his way to build a motor driven biomimetic hand. It's for humans eventually, so not much space for sensors right now, which can't be wired to humans anyways. He knows a lot about hands and we might be able to learn from it, and build something (even much smaller) for our waifus. Redesign: https://youtu.be/-zqZ-izx-7w More: https://youtu.be/3pmj-ESVuoU Finger prototype: https://youtu.be/MxbX9iKGd6w CMC joint: https://youtu.be/DqGq5mnd_n4 I think the thread about sensoric skin >>242 is closely related to this topic, because it will be difficult to build a hand which also has good sensory input. We'll have to come up with some very small GelSight-like sensors. F3 hand (pneumatic) https://youtu.be/JPTnVLJH4SY https://youtu.be/j_8Pvzj-HdQ Festo hand (pneumatic) https://youtu.be/5e0F14IRxVc Thread >>417 is about Prosthetics, especially Open Prosthetics.

Kiwi here to teach fellow Anons. First is how to make a ball and socket that pop together with side guides. These guides turn it into a universal joint. You can incorporate this design into many different other designs, I recommend using petroleum jelly to smooth out the motion. For reference, the ball is a 12 mm sphere. The socket has an internal 13 mm sphere and the mm difference is necessary at all scales. More tutorials will come. All information is freely given for the sake of catgrill meidos.

>>14855 >*Random anon wanders by* If this is of interest to you look at the engineering of snap fittings, which is what such "clips" are called. There's a lot more to it. For example, your snap fit uses a return angle of 90 deg, which locks the snap fit. Using a larger return angle makes it possible to pull out the snap fit (i.e. you can tailor the amount of force needed). The material, and fabrication method (e.g. FDM as in your example, or injection molded) all make significant differences to the design and how it functions. Useful resources: 2 books attached + https://www.hubs.com/knowledge-base/how-design-snap-fit-joints-3d-printing/ You may also be interested in things like "living hinges" and "compliant mechanisms" in the future.

R&D General Robowaifu Technician 09/10/2019 (Tue) 06:58:26 No.83 [Reply] [Last]
This is a thread to discuss smaller waifu building problems, solutions, proposals and questions that don't warrant a thread. Keep it technical. I'll start.

Liquid battery and cooling in one
Having a single "artificial blood" system for liquid cooling and power storage would eliminate the need for a vulnerable solid state battery, eliminate the need for a separate cooling system, and solve the problem of extending those systems to extremities.
I have heard of flow batteries, you'd just need to use a pair of liquids that's safe enough and not too sensitive to changes in temperature.
This one looks like it fits the bill. The downside is that your waifu would essentially be running on herbicide. (though from what I gather, it's in soluble salt form and thus less dangerous than the usual variety)

How close are we to creating artificial muscles? And what's the second best option?
Muscles are perfect at what they do; they're powerful, compact, efficient, they carry their own weight, they aren't dependent on remote parts of the system, they can be controlled precisely, and they can perform many roles depending on their layout alone.
We could grow actual organic muscles for this purpose already but that's just fucking gross, and you'd need a lot of extra bloat to maintain them.
What we need are strands of whatever that can contract using electrical energy. Piezo does the trick at small scales, but would it be enough to match the real thing? There have been attempts, but nothing concrete so far.
What are some examples of technology that one could currently use instead?

High level and low level intelligence emulation
I've noticed a pattern in programs that emulate other computing hardware.
The first emulators that do the job at acceptable speeds are always the ones that use hacks and shortcuts to get the job done.
It comes down to a tradeoff. Analyzing and recompiling or reinterpreting the code itself on a more abstract level will introduce errors, but it is a magnitude of order more efficient than simulating every part of the circuitry down to each cycle. This is why a relatively high level emulator of a 6th gen video game console has close system requirements to a cycle-accurate emulator of the SNES.
Now, I want to present an analogy here. If training neural networks for every damn thing and trying to blindly replicate an organic system is akin to accurately emulating every logic gate in a circuit, what are some shortcuts we could take?
It is commonly repeated that a human brain has immense computing power, but this assumption is based just on the amount of neurons observed, and it's likely that most of them probably have nothing to do with intelligence or consciousness. If we trim those, the estimated computing power would drop to a more reasonable level. In addition, our computers just aren't built for doing things like neural systems do. They're better at some things, and worse at others. If we can do something in a digital way instead of trying to simulate an analog circuit doing the same thing, that's more computing power that we could save, possibly bridging the gap way earlier than we expected to.
The most obvious way to handle this would be doing as many mundane processing and hardware control tasks as possible in an optimized, digital way, and then using a GPU or another kind of circuit altogether to handle the magical "frontal lobe" part, so to speak.

I bought something called Rivet. I hope I can use these inside bigger rollers as axis, shaft or pivot. Or in some cases to join parts together without needing to add screws and nuts. Gluing one side into a hole might be good enough. In other cases only one direction needs to be constrained.
>>19398 Get the rivet gun that will set these for you also. With these, you can tack together sheets of stuff w/o needing a substrate support at that spot (eg, a wood strut for a screw or nail to drive into. you won't need that).

When 3D printing, some designs require really tight tolerances. Due to the nature of different brands of filament and colors of filament behaving slightly differently, it can be ideal to use built in clamps to ensure a tight fit. picrel includes a test to prove effectiveness and the CAD design to help inspire Anons when they make their own.
>>19408 That looks pretty sophisticated, actually. Can you break the ideas out a bit further for the uninitiate, Kiwi? How is the 'built-in clamp' acting in the dynamics of your pic-rel, for instance?
>>19408 Looks like a great idea. Though, I would like to add that this should then be done in PETG, not PLA (bc creep). Also I'd still prefer something relying on metal to make sure this will hold up over time.
