(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!

Power & Energy Robots require some form of energy to power them. We need to understand how to store energy in a way that will provide her with all the power she’ll need. To clarify, “energy” is a system's capacity to do work over time. This is measured by Wh, or Watt hour. Closely related is “power” the rate at which work is done. This is measured as W, or watts. As an example, we could have a robot with a 80Wh Lithium Ion battery and two DC gear motors that consume 10W when working. You do not need to rely solely on batteries and motors. We can use other methods of storing energy. This can include compressed fluids, thermal energy, and light, among other things. For instance, glow in the dark paint is useful for storing energy to use at night for safety. Solar panels or a generator can provide power through the energy of long distance nuclear fusion or extracting energy from some reaction. Being part of a robot means we need to consider safety, mass, and volume. How will her energy and power system fit inside her? How will she deal with the mass? What happens when she runs out of energy? How can you minimize her energy use? What alternatives can be used to lower her cost of production and ownership? These rhetorical questions are all important when contemplating how to build a robot.

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.

Tensegrity Thread Tenssegrity is the purposeful application of tension in a system of non-contact components to provide integrity. These components effectively float on compression provided by tension elements. Tensegrity structures are often formed via rigid rods with a cable defining the spatial relations of the system. Picrel 1 is NASA’s Super Ball Bot, which uses the common 6 bar structure. By altering the lengths of the rods, the “ball” can roll. Please see (https://www.nasa.gov/image-article/super-ball-bot/) Our bodies use tensegrity to provide us with incredible strength, durability, and adaptability. Consider how when you bump into something or fall, you can feel the pressure dissipate throughout large parts of your body. This is due to your muscles, fascia, ligaments, etc… transferring the force throughout your body, protecting the impacted part. You can walk with little effort thanks in part to tensegrity. Your legs joints are all floating, providing low friction movement while distributing the force of impact throughout your entire leg when you step. Please see (http://intensiondesigns.ca/geometry-of-anatomy/) Tensegrity can also be made with elastic elements. These structures are what I believe are best suited for our endeavors. They provide looser tolerance requirements and give her body some squeezability. By incorporating naturally stretchable elements, she can better withstand having an Anon using her. (I speak from experience, though I still broke that torso before taking pictures.) Though there are drawbacks. These designs are deceptively difficult to design correctly. Our requirements for external aesthetics provide unique design requirements that complicate the design phase. I still believe using this concept is objectively correct for us to pursue. A good example to build off of (Debatable whether or not it’s true tensegrity): https://www.thingiverse.com/thing:4182634

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.

This thread is for discussion, warnings, tips & tricks all related to robowaifu privacy, safety & security. Or even just general computing safety, particularly if it's related to home networks/servers/other systems that our robowaifus will be interacting with in the home. <---> /robowaifu/ 's standard regarding a robowaifu's physical safety : ( >>38561 ). --- > thread-related (>>1671) >=== -update OP -broaden thread subject -add crosslink -add safety-standard crosslink

Scientists made a neural network from rat neurons that could fly a fighter jet in a simulator and control a small robot. I think that lab grown biological components would be a great way to go for some robowaifu systems. It could also make it feel more real. https://www.google.com/amp/s/singularityhub.com/2010/10/06/videos-of-robot-controlled-by-rat-brain-amazing-technology-still-moving-forward/amp/ >=== -add/rm notice
