I decided to copy my post from the visual waifu thread
>>43010 about my marionette sex doll idea, since I didn't do that before; it's been edited slightly for context. For those who didn't read that thread, it's intended to be used with an AR visor that projects an image of your desired waifu onto an inert love doll while having sex with her; the doll is hooked up to a marionette-like cable system that enables her to move. Hopefully soon I'll have some time to do some more concentrated work on the visual waifu project, but I want this to be in its proper thread.
Marionette Waifus And You: A Solution for the Robo-Sex Problem Using Current Technology
This is how we could enable the most immersive illusion of holowaifu sex. With this, you could buy an inert love doll (already exists and is far cheaper than a fully motorized and autonomous robowaifu) and plant a context-sensitive tracking marker on the doll to have the AR visor project your holowaifu onto her within a mixed VR/AR world that creates a digital clone of your environment. This is good enough for motionless starfish sex where the girl lies there like a pillow princess, something a normal inert waifu doll can also do. But unlike a normal waifu doll (or the starfish sex in a Reddit-tier betabux relationship), your waifu will smile and moan back at you in the AR world as she tells you she loves you.
With this feature in place, we've officially surpassed even the minority of betabux relationships that actually give monthly starfish sex and aren't completely dead bedroom affairs that feature the roastie cucking the paypig with Tyrone and giving the cuck nothing. But we're not done innovating yet. We're going to go even better: If you want your waifu to be capable of multiple forms of sexual positioning and moving with you as you have sex with her, you could use the visor with an inert love doll rigged up with an external robotic frame mounted on a wall near your bed, which is much simpler to implement than building the robotics directly into the waifu doll. You could use a green screen-like system so the external robotics aren't picked up for rendering into the VR/AR hybrid environment, so that when you wear the AR visor and go into the AR world, it looks like your waifu is moving on her own.
Your holowaifu will then be able to ride you, twerk on you, and do many other sexual acts, and it will look and feel realistic. Of course you could just have the robotic frame and the love doll without the visor, but the visor would increase immersion and let you easily customize your waifu's appearance, and make it possible for your waifu to follow you around without the need for a full-blown robowaifu using the already-established AR functions simply by telling her to disengage from the doll and become a pure hologram again.
This "Sexoskeleton" setup would appear very similar to the Major on the original Ghost in the Shell movie poster (pic related); a naked girl with a bunch of marionette-like cables and robot things connected to her. There would be limits to the sex positions you could do (pile driver, wheelbarrow and other uncommon positions could be difficult), and shower sex is off the table for numerous reasons, but you can do most standard positions. The robotic frame would probably be largely cable-based, as maneuvering the AR-enhanced waifu doll through the use of a power armor-style rigid robotic exoskeleton is both difficult and probably unnecessary, and having a set of flexible cables as the primary actuators and support structures increases the amount of positions you can do because you won't have hard robot arms getting in your way.
This is in some ways an improvement over the standard robowaifu concept, as it doesn't require complex navigational AI (or the substantial amount of maintenance and power consumption difficulties associated with a standard robowaifu); the AR visor uses about as much power as a smartphone, the robot frame can just plug into the wall, and the waifu only even has a body when she's having sex with you, and the rest of the time she's an AR hologram that can remove herself from the love doll and follow you around at your pleasure. And most crucially, removing the robotics from inside the waifu and implementing them as an external robotic frame fixes numerous issues and costs orders of magnitude less than a full robowaifu while fulfilling the primary purpose that 99% of robowaifu buyers have for her. It doesn't give you full autonomous robot functionality; instead it strips down the problem robowaifus are attempting to solve to the bare minimum and gives you the all-important function of being able to have realistic sex with her, and it does this using established technology with minimal new developments needed.
Obviously we can't do the GITS poster Major setup to start with, as even this is a pretty tall order (although not nearly as tall as developing a full robowaifu). But it's a good goal to work towards, because even if robowaifu technology became viable, it would likely be limited to the very rich. But once the new AR technology matures, average guys could afford something like this - or even build it themselves using DIY instructions because the skill level and equipment requirements are the kind found in high school and college robotics clubs, not professional industry. I think this solves a lot of core robowaifu problems, and I'm interested in hearing appraisals of its feasibility and desirability.
