Robowaifu Ethics & Morality Chobitsu 08/02/2022 (Tue) 23:25:26 No.17125 [Reply] [Last]
>"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

>>41933 >digits confirm Oh, no disagreement from me on that one, Anon. Thus why I quoted the word, for the implying implications of it. :D In fact, any efforts on our parts to invoke any supernatural entities getting involved with the effort would surely lead to evil outcomes -- and I very-strongly advise against any such endeavor. You're right that God alone creates real souls! <---> Having said all that, I firmly believe we will devise simulacrums of & for our robowaifus that are: * Effective * Pleasing * Loving I personally feel that will be quite good-enough an achievement for us here, and will surely be a blessing from the Lord when it is accomplished!

My Advanced Realistic Humanoid Robot Project - Eve Artbyrobot 04/18/2024 (Thu) 17:44:09 No.30954 [Reply] [Last]
So far I have plans to build Adam, Eve, and Abel robots. All of these are Bible characters. This thread will cover the Eve robot. Eve will have no "love holes" because adding those would be sinful and evil. It is a robot, not a biological woman after all and I will view her with all purity of heart and mind instead of using her to fulfill my lusts of my body. Instead I will walk by the Spirit no longer fulfilling the lusts of the flesh as the Bible commands. Eve will be beautiful because making her beautiful is not a sinful thing to do. However, I will dress her modestly as God commands of all women everywhere. This would obviously include robot women because otherwise the robot woman would be a stumbling block to men which could cause them to lust after her which would be a sin. To tempt someone to sin is not loving and is evil and so my robot will not do this. To dress her in a miniskirt, for example, would be sinful and evil and all people who engage in sinfullness knowingly are presently on their way to hell. I don't wish this for anyone. My robot will dress in a way that is a good example to all women and is aimed toward not causing anybody to lust as a goal. My robot will have a human bone structure. It will use either a PVC medical skeleton or fiberglass fabricated hollow bones. My robot will look realistic and move realistic. It will be able to talk, walk, run, do chores, play sports, dance, rock climb, and do gymnastics. It will also be able to build more robots just like itself and manufacture other products and inventions. I realized with just a head and arm, a robot can build the rest of its own body so that is my intention. My robot will use BLDC motors for drones, RC, and scooters that are high speed and low-ish torque but I will downgear those motors with a archimedes pulley system that will be custom made from custom fabricated pulleys that will be bearings based. By downgearing with pulleys, instead of gears, I will cut down the noise the robot makes so it will be as silent as possible for indoor use. By downgearing, I convert the high speed motors into moderate speeds with great torque. BLDC motors with large torque generally are too large in diameter for a human form factor and take up too much volumetric area to be useful which is why I go with the high speed smaller diameter type motors but just heavily downgear them 32:1 and 64:1. My robot will have realistic silicone skin. Thom Floutz -LA based painter, sculptor, make-up artist is my inspiration as it pertains to realistic skin. The skin for my robots has to be at his level to be acceptable. It must be nearly impossible to tell the robot is not human to be acceptable. I will have a wireframe mesh exoskeleton that simulates the volumes and movements of muscle underneath the skin which will give the skin its volumetric form like muscles do. Within these hollow wireframe mesh frameworks will be all the electronics and their cooling systems. All of my motor controllers will be custom made since I need them VERY small to fit into the confined spaces I have to work with. I need LOADS of motors to replace every pertinent muscle of the human body in such a way that the robot can move in all the ways humans move and have near human level of strength and speed.

I started some testing on some subsections of the BLDC motor controller and ran into some problems and learned several things. I'm working with chatgpt to resolve each issue and have been updating my schematic to reflect alot of the changes I am making. One thing I learned is that for the high side switch, the voltage from gate to source has to be 10-12v higher than the drain voltage because the drain voltage becomes the same as the source voltage once the switch is on. The voltage from gate to source then either has to start out as motor input voltage + 12 while still fitting within the voltage from gate to source max allowed voltage as stated by the datasheet or it has to rise dynamically as the source voltage rises such that the voltage from gate to source is 12 more than the source voltage as the source voltage rises to become the drain voltage. Fortunately, I can have the former for this 2430 motor since I can use 6-8.4v to supply the motor and the voltage from gate to source max value is 20v. This means I can use voltage from gate to source of 20v and this, when mosfet is first switched on, does not fry mosfet but as the source rises to become 8.4v, 20v-8.4v is still 11.6v which is sufficiently high to enable the mosfet to still stay on without anything dynamic set up. If I want to go with a 12v motor supply on some of the bigger motors later on, I will need a bootstrap circuit to supply the highside mosfet with a dynamic voltage from gate to source that rises when source voltage rises. So I added that schematic diagram to this as well as an option. I also can use a mosfet driver for this but was hoping to cut that cost and added volume taken up by just using discrete components rather than a IC for this. Anyways, to break things down even more in testing, I decided to just test turning on and off a single highside mosfet using a pair of lab power supplies, one to provide 20v and one to provide 8.4v. To turn on I connected the gate and source to my 20v lab power supply and I connected my red alligator clip of my 8.4v lab power supply to the drain and then measured from source to the black lead of the 8.4v power supply and verified 8v on that test which worked - proving the mosfet was in fact on. I then removed the black alligator clip of the 20v lab power supply from source and shorted the source to the gate to drain the internal capacitor inside the mosfet and then tested from source to the black 8.4v clip and sure enough it was near 0v so was off. But it did gradually climb back up to 8.4v after the short from gate to source was removed due to capacitive coupling and leakage according to chatgpt. So I will need to add a 10k ohm resistor between gate and source pins to short it automatically and keep it fully drained and off fully when it's supposed to be off.
So I plan to just gradually add components little by little and test after each thing is added to ensure it is working right still after each little change and this way gradually build out the circuit, proving each thing works as we go. This is because things have all these gotchas and "oh you didn't know this little detail?" that keeps coming up and proves it was more complicated than I thought. So I just have to prove every little thing as I go. To try to find out what is wrong after the whole thing is built would be WAY harder than to figure out what went wrong when a single component is added and it was working before said component was added. So that's how I will be able to overcome this challenge best I feel. Note: Reminder: I am building a custom BLDC motor controller because an off the shelf one would not have enough miniaturization to fit into the tight space constraints I have to work with. Also, building my own gives my software more precise control of every little advancement of the rotating magnetic field and along with that I'll have the ability to PWM the advancements to make them more smooth, less noisy, and have torque control as well this way which means the fingers can be rough and fast in movement as needed or slow and gentle and dainty or slow but powerful etc. I can also create acceleration profiles that match human finger joint acceleration in order to have the movements look very natural just like a human's movements which is very important to me. Just alot of fine precision is possible when its all my own circuit I feel. While off the shelf ones may have some of this functionality, the price often reflects that and is then prohibitive. But in any case nothing is off the shelf with this level of control AND the ability to so finely tune its form factor and volume envelope to fit my exact needs in space on a per motor basis.
>>41750 >>41751 >So I plan to just gradually add components little by little and test after each thing is added to ensure it is working right still after each little change and this way gradually build out the circuit, proving each thing works as we go. This is because things have all these gotchas and "oh you didn't know this little detail?" that keeps coming up and proves it was more complicated than I thought. So I just have to prove every little thing as I go. I think that's how learning complex phenomenon often go -- at least if you're meaning to make something actually work (as engineers do). Conversely, a research scientist once remarked to me during dinner that they had it easy in this regard, since they can just talk about how things are! :D
Well I finally got back to the electronics after about a month long detour real life interruption. All kinds of stuff slowed my progress on this session. But I got stuff done nonetheless. 0603 LED to 0805 resistor and some nickel strip leads coming off. Tested and working. This will be the indicator light for when the lowside mosfet comes on for one section of the custom BLDC motor controller. 0603 LEDs are extremely tiny for hand soldering and they don't take solder well either. I was originally going to go with blue LEDs but chatgpt said that would give off a unrealistic color through the silicone skin so orange would be better to give a more natural and less silicone skin piercing indicator light. Somehow I ran out of 470ohm resistors so I had to order more and I used my 200ohm ones instead for now. Which are a bit too bright. But chatgpt said I can diffuse the LED with a glob of silicone tinted black to darken and diffuse the light it gives off which sounds like a good idea to me. I am planning to use wire wrapping wire to come off of this assembly and tie into things. Somehow just attaching these two parts and testing it took me almost 3 hours. Between studying the schematic to refresh my memory on what is going on, visualizing placement options, overheating and destroying one LED, trying to locate the right color LEDs, shopping for replacement 470ohm resistors, researching and substituting in 200ohm resistors, discussing LED color options with chatgpt, figuring out how to solder a 0603 LED directly to a 0805 resistor part to part by hand, accidentally breaking a part off of its nickel strip lead and having to redo the connection, etc etc. All of it just crawls. Hard to stay patient with electronics sometimes and I do things in inefficient ways often. Learning what can and aught not to be done is tough from a patience perspective. But I insist on trial and error and experimentation which takes time. I just need to get into a daily habit to stick with it till completion. It's all complicated. Trying to figure out how to electronically isolate it all next. Thinking of using lamination plastic taped around it all so I can still see it all and visually troubleshoot. Also I'm considering how I can use solder wick braid as a heat pipe for each mosfet and run that over to the liquid cooling system. But it can't conduct. So thermally it can conduct but electrically it can't. Trying to figure out whether to create a barrier of micah or just thermal silicone for this and the routing needed. Also considering if I need mini coaxial shielded cable for the wiring of each or just regular wire wrapping wire when going from microcontroller to mosfets etc. Also trying to figure out if I need hall effect sensors or back emf reading or no feedback but my potentiometer and the implications of each option. Just so much to consider in all of this. And all of those considerations also slow things down even more as I have to make decisions on it all. It's quite overwhelming.
>>42398 It's so wee! :D >200ohm resistors Couldn't you have used a 1K? >Thinking of using lamination plastic taped around it all I can highly recommend Kapton tape as a fantastic general-use one, & well-suited to this specific need. --- Anyway, nice work Anon. Glad to see you back at it! Patience & Godspeed, Artbyrobot. Cheers. :^)

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.

Actuators For Waifu Movement Part 3 Kiwi 12/06/2023 (Wed) 01:18:16 No.27021 [Reply] [Last]
(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!

>>42267 Essentially, they started with two voice coils to manipulate the tendons of the leg. This makes some sense as moving coils is easier than moving the magnets as their lower mass means less inertia. This failed spectacularly as the current needed to move its own mass caused the coils to burn. They tried using mechanical tricks to no avail. It ends with him saying he's just going to use off the shelf solenoids because manufactured solenoids have better tolerances, leading to far better efficiency. >AFAICT from your post, your position is that we need perfect, tiny little brakes to lock all the skellington's elements into proper places (and very dynamically!) -- but at a level currently seen as infeasible to produce rn. Is that it? I presume the primary point being, is that the current drain through the coils to do so otherwise is exorbitant? That is correct, it's frustrating for me.
>>42295 Metal clay and metal infused filaments can also be used to make metal parts, but I am not sure how great the resolution is. https://shop.thevirtualfoundry.com/ https://cooltools.us/collections/clay
>>42290 >How do they infuse the metals metal salts, then the metals in the salts are "precipitated" with a different chemical, salt washed out metal stays, leaving the metal, then infused again, repeat. Each time leaving more metal. Then baked to fuse. The advantage of this appears to be small feature sized parts, low cost as you are using regular resin printers and not expensive specialized powder direct metal laser sintering (DMLS). The deficit is longer times infusing these metal salts, then precipitating them out into metals with 10 of these steps in some cases. Another benefit is it appears, I think, that this makes much stronger parts as the salts are deposited as nano particles making strong parts.
>>42297 Thanks kindly, Kiwi! >It ends with him saying he's just going to use off the shelf solenoids because manufactured solenoids have better tolerances, leading to far better efficiency. Makes good sense at this point in time, IMO. Hopefully we'll be able to craft high-qual windings &tc. soon-ish. >That is correct, it's frustrating for me. OK, glad I got the gist from your posting alone. Hmm. We've discussed devising some kinds of disc brake systems for skellingtons here a few times IIRC. Seems to me this would be a reasonable approach. But machining metals for it all is the primary issue IMO. I wonder if we can craft such things that would be durable enough using resin printing instead?
>>42298 Thanks, Anon! >I am not sure how great the resolution is. Certainly I'd expect it to be coarser than resin printing? >>42299 I see, thanks Grommet! Hmm. Sounds like a drawn-out process, and potentially-hazardous leachate byproducts? I wonder if these issues can be resolved simply enough?

Qualcomm has been keeping up a very brisk pace for over a year now on their "Intelligent Robotics" SDK releases. https://docs.qualcomm.com/bundle/publicresource/topics/80-70020-260/robotics-sdk-july-2025.html --- One of the biggest PITA with so-called """ROS""", is the horrendous dependency hell involved with setting it up from scratch (along with it being incredibly finicky thereafter to bringing in new libs as well). Qualcomm apparently pulls some of ROS's core packages into their own SDK binaries, so the potential is there at least to eliminate this whole issue outright.

>>42270 >>42271 Heh, OK fair enough then. :^) >guayule Figured you might find this intredasting: https://www.bridgestone.com/technology_innovation/natural_rubber/guayule/ >Mexican honey wasps Neat! I don't normally care much for wasps, but that would be really neat. Good luck with this endeavor if you pull the trigger on it, Ribose. I'd love to see you all pull it off! Cheers. :^)
>>42272 Exactly why I am interested in Guayule. It is a rubber crop that doesn't compete with food.
>>42273 Sounds good, Anon. Again, good luck! Cheers. :^)
Seems its time for a new thread, OP Maybe something a bit more "robowaifu'y" for the OP pic this time please? :^)

Since we have no thread for hands, I'm now opening one. Aside the AI, it might be the most difficult thing to achieve. 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. This can be relevant to some degree. However, the constraints are different. We might have more space in the forearms, but we want marvelous sensors in the hands and have to connect them to the body.

Related: >>35641 >Functional evaluation of a non-assembly 3D-printed hand prosthesis > ... developed a new approach for the design and 3D printing of non-assembly active hand prostheses using inexpensive 3D printers working on the basis of material extrusion technology. This article describes the design of our novel 3D-printed hand prosthesis and also shows the mechanical and functional evaluation in view of its future use in developing countries. We have fabricated a hand prosthesis using 3D printing technology and a non-assembly design approach that reaches certain level of functionality. The mechanical resistance of critical parts, the mechanical performance, and the functionality of a non-assembly 3D-printed hand prosthesis were assessed. The mechanical configuration used in the hand prosthesis is able to withstand typical actuation forces delivered by prosthetic users. Moreover, the activation forces and the energy required for a closing cycle are considerably lower as compared to other body-powered prostheses. The non-assembly design achieved a comparable level of functionality with respect to other body-powered alternatives. We consider this prosthetic hand a valuable option for people with arm defects in developing countries. https://journals.sagepub.com/doi/epub/10.1177/0954411919874523
>>38171 POTD Really exciting to see his progress with this new print-in-place design. Thanks, Anon! Cheers. :^)

>>42182 Current will be resisted one way and not the other due to magnetic fields "pushing" each other. AC current will be resisted due to inductive reactance. Look into chokes and similar for more information. https://en.wikipedia.org/wiki/Choke_(electronics)

>>42184 >>42183 I forgot to mention a part because I was having internet connection issues. I meant to ask what would happen with that core in a voltage-boosting circuit like a joule thief. All the AI answers I've gotten just say that it just makes the circuit less efficient.
>>42188 >Magnet in joule thief inductor This would make it far less efficient. You're storing electricity in a magnetic field, then using its collapse to send a high voltage pulse to the LED. A magnet in the inductor will create a reactance resisting the flow of current in either the buildup or collapse phase, depending on orientation. This will result in the inductor and magnet getting heated in proportion to the energy losses fighting the magnetic field. To provide an analogy, imagine the current flow is water. In this example, the water is building pressure to open a door that has a spring behind it to ensure enough water pressure is built up. Your magnet would be adding a paddle attached to a source of friction that varies in resistivity depending on direction of current flow. It just makes the system worse. Please don't do this, it's a waste of power and a magnet. I'm curious how you came to this idea?

>>42201 There was a patent for a free energy device called the "motionless electromagnetic generator" or MEG that is basically a transformer with a magnet in it, and some people have demonstrated an increase in amperage output from it even without tuning the input frequency for the most efficient output: https://www.youtube.com/watch?v=xvNyDp_XYYw But having seen the patent & being familiar with how patents often lie by omission to keep people from successfully replicating the invention, the first thing that came to mind was that if the input coil was an air core pulsed with DC to negate the permanent magnet, then the flux would leave the output coil, creating a pulse of current, then when the DC input failed the flux would return to it on its own, creating another pulse in reverse. The original patent just says AC, and the flux from the permanent magnet & the input coil both go to the output, which only seems necessary because the flux wouldn't return on its own. I was thinking about making a self-oscillating circuit like that Joule Thief and had the idea to combine it with my modified MEG concept, but trying to think of how to do it with a single ferrite core. My first thought was to make the building-up part reinforce the permanent magnet's field and when it collapses make the output of the Joule Thief power the coil that switches the flux of the permanent magnet. I wasn't sure what effect this would have on the efficiency, so I figured I'd ask here. I wasn't sure if reinforcing the permanent magnet with an electromagnet would be useful in any way, so I thought of just removing the permanent magnet entirely.
