I envision an articulated skeleton, incremental improvement, but rather than a solid foam core, a system of muscle-shaped material that moves with the joints. And the skin slides along over top. The foam core does a lot to save weight, so probably don't want to fully simulate the muscle structure, but at least the layer just below the skin has the shape of muscle, and a higher durometer than the skinrubherkitty wrote: Yeah, I'm just talking about doll shaping under the skin. I've seen the muscle tech you're talking about. Probably too high tech to incorp in dolls right now anyway. I figure doll movement will be the std electro servo's, linkage, etc. I do have some plans drawn up for a silicone skin doll that has hip movement via a 12v single arm windshield wiper motor. This project will have to wait awhile as I just spent a bunch of time finishing a ball joint doll.
Foam inner core pieces. Outer muscle that you feel could be silicone mesh bags w/ foam core. Different silicone and foam durometer for different density of muscles. The foam core pieces could be molded onto the skeleton. The muscle pieces attached via velcro or something. This way you could cut or remove the skin then remove the muscle pieces if the doll needs repair.
Maybe a foam core then a soft foam skin over that onto which only the major muscle groups are attached?
Something a inventor will just have to play around with. If I really got serious about this I would do some research on some of the humanoid robots already out there to see what they have come up with. For my cheapy home made doll I was just going to use stuff like pool noodles or foam insulating pipe covers. Socks stuffed tight w/ polyfill. Foam from old seat cushions. Skin would be silicone coated unitard or long underwear. She would be more of a black silicone catwoman type of doll.
