>>13417979The version I'm talking about could dance, jump, fly, ride on your dick, fly, etc. The reason for the rail mounting is that the arm would be out of the way. It doesn't need to be entire length of the room if you live in a palace or something, it can be a simple power lifting cage, I'd be happy if it covered my workstation and bed, which are just 4 meters apart. I can sit on my lap, get fucked on my table or on my workbench missionary style, cowgirl me on the bed, give me a reach-around handjob while I work.
And when it becomes "obsolete" you could still use the most of it. Because the only thing that the robotic arm is move the unit around and act as an extension cord. The reason I go this route is accessibility to the tech and being able to build it yourself, instead of waiting Elon Musk type of savior to do it for you. Most of the tech is already there.
