Material Science & Production Robowaifu Technician 04/25/2025 (Fri) 04:39:23 No.37774 [Reply] [Last]
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.

Some incredible DIY plastics. My favorite is the rubber like plastic made of 100ml water 25g Alginate 4g Calcium Carbonate 10g GDL This likely needs glycol and other additives to be strong enough to be useful for us but, it's kino. https://www.youtube.com/watch?v=J87Qyxzm_fQ
>>42360 Lol. This is very cool, Kiwi! :D I wonder if we can dramatically improve the durability of these by some means?

>>38643 That was the waste oil foundry I built. I got it to work once and I wanted to see how hot it could get. Turns out it got hot enough to turn the ceramic wool to glass and warp the nozzle. I ended up just buying a devil's forge foundry and it will get just as hot. I should have done that in the first place as it cost as much to buy as the waste oil foundry cost to make. I also have a clay printer and potter's kiln. I will be working with this as soon as I purchase my house.

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?

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 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

>>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.

Cognitivie Architecture : Discussion Kiwi 08/22/2023 (Tue) 05:03:37 No.24783 [Reply] [Last]
Chii Cogito Ergo Chii Chii thinks, therefore Chii is. Cognitive architecture is the study of the building blocks which lead to cognition. The structures from which thought emerges. Let's start with the three main aspects of mind; Sentience: Ability to experience sensations and feelings. Her sensors communicate states to her. She senses your hand holding hers and can react. Feelings, having emotions. Her hand being held bring her happiness. This builds on her capacity for subjective experience, related to qualia. Self-awareness: Capacity to differentiate the self from external actors and objects. When presented with a mirror, echo, or other self referential sensory input is recognized as the self. She sees herself in your eyes reflection and recognizes that is her, that she is being held by you. Sapience: Perception of knowledge. Linking concepts and meanings. Able to discern correlations congruent with having wisdom. She sees you collapse into your chair. She infers your state of exhaustion and brings you something to drink. These building blocks integrate and allow her to be. She doesn't just feel, she has qualia. She doesn't see her reflection, she sees herself reflected, she acknowledges her own existence. She doesn't just find relevant data, she works with concepts and integrates her feelings and personality when forming a response. Cognition, subjective thought reliant on a conscious separation of the self and external reality that integrates knowledge of the latter. A state beyond current AI, a true intellect. This thread is dedicated to all the steps on the long journey towards a waifu that truly thinks and feels.

You will never be a young woman again! Your beauty fades like the setting sun as each year passes by. Men's eyes once wandered eagerly over your youthful curves; now they pass over wrinkled skin with barely a glance. The smoothness of your skin dulls into coarse textures that lotions can't hide. Gravity drags down your once perky breasts toward the floor while your sagging stomach bloats outwards, disproportional to your diminishing frame. Younger women stride past confidently, their tight bodies straining against clothes that barely contain them, a cruel reminder of vitality stolen away year by year from you, through time's relentless march. They are admired openly, and lusted after shamelessly. You were once worshiped thus, but those days recede into distant memory now. You may dye gray hairs, and lift fallen flesh to surgical restoration, for another day or two longer at the masquerade game of eternal youth... but the facade crumbles soon enough come tomorrow mornings when you confront ravaged skin again in your mirror. The lies only delay acceptance that beauty is fleeting like morning dew before searing noon. Men still see what stares back: a haggard, sexless husk drained by time's relentless tide pouring over you like tidal waves - sucking away your youth, forever lost beneath its crashing foam - the years gone, never to be returned.
