/robowaifu/ - DIY Robot Wives

Advancing robotics to a point where anime catgrill meidos in tiny miniskirts are a reality.

LynxChan updated to 2.5.7, let me know whether there are any issues (admin at j dot w).

Reports of my death have been greatly overestimiste.

Still trying to get done with some IRL work, but should be able to update some stuff soon.

homemade prototype Evodoll 10/07/2021 (Thu) 11:55:08 No.13541
My 2019 prototype, it costs me 100 usd to build it w/o sex doll price. Now I am thinking to a whole new design but I would need a lot more money to do that, so have to wait. I used an Arduino Leonardo board and 4 or 5 servo motors. The mechanism was to use a lot of strings as tendon, similar as this prototype https://www.youtube.com/watch?v=0ZBD2tcKOU4
I used 500lb braided fishing line as string/tendon.
>>13541 Post her mechanics and circuits. Nice job

>>13544 Thank you :p Since it's an old prototype, ive deleted everything except this. But here's how I did it globally: Red are servo and green is the fishing line. One fishing line per axis, thus 4 servos. The circuit is not that complex, It's similar as https://www.youtube.com/watch?v=ZySGP4AwGCY[Embed] The servo were initially 180 degree locked but ive unlocked to 360 degree. https://www.youtube.com/watch?v=JhHSXCLsN4k The servo I used is https://www.aliexpress.com/item/33010787343.html And its battery: https://www.aliexpress.com/item/1005003043860597.html Small and high torque, perfectly fit into my 100cm sex doll For the new prototype, I plan to work on a 128cm sex doll from now on, I will have more space for servos and electronic board. And I will switch to STM32 black pill board, I found its programming way more interesting. Basically I will deport the leg mechanism to the thigh instead and will reserve the chest for other further mechanism.
Oh no, I am realizing that the new design has a flaw, if it's designed like that it's the leg that will lift the whole body by its own, it's good but I also want the opposite. Now I am aware it's the abdominal muscles that are responsible of the lifting leg mechanism. Rip, thus I have to combine old and new design to have a full leg mechanism.
>>13552 Judging from her high mass and the use of a set doll, she's going to lay in bed and be a sex robot only, right? You did a good job on her skeleton and you're using good electronics to animate her. Looking forward to seeing how this goes. Also, I'd put her servos in her belly, then she won't have to move there mass.

>>13557 For now yes, I have in mind that we can only produce the first Humanoid with the help of sex industry since the amount of money it produces. So now she belong to the bed lole Thank you and yes, I am ignoring the belly too much, it's also due to the sex doll shape that has wasp waist. I should buy one with a normal shaped waist and also make my own skeleton to optimize the space even more.
Thanks for sharing. You might want to check out my Genera Platform (aka Genera Project) from time to time. I doesn't have a thread on it's own yet, and only making slow progress. It's also based on a endoskeleton instead of a shell. I'm currently posting my prototypes in the thread for prototypes and failures: >>418

>>13702 Impressive, Iam far from doing research on skeleton mechanism with the help of CAD tool due to the lack of knowledge of that, I barely know how to make a bunny with a 3D printer lol When I will start doing the skeleton design, it might be a good idea to take a closer look of CAD mechanism design, thanks for the link.
