Well I agree with you GreerTech when robowaifus are the design target. This Sumomo-chan project is just a headpat daughteru, as I mentioned. Later, once all the bugs have been ironed out for both the opensauce (MIT-licensed) hardware & software of Sumomo, then all the hardware knowledge learned from that project can (mostly) be transferred over to fullsized robowaifu lines. The software will 100% transfer over -- more-or-less directly (specific model's [like Sumomo-chan, Chii-chan, MaidCom, etc] design's individual physical/electronic characteristics are simply tweaked-in via config textfiles -- the main system's command, control, & communications (C3) software is generalized to work with them all [including the little robopony steed for Sumomo-chan: Buckey; ie, quadrupeds]).
>Galatea and The Masiro Project are in that range.
You've done a wonderful job with dear Galatea thus far, Anon. You're going to pay some penalties in mass once you begin to robo-articulate her (actuators, batteries, connective struts, current-carrying wiring, hefty driver electronics, etc.) Concerning mass, dear Masiro Sisters are already very heavy, probably in the range of our own Lin's 'wheeled waifu project'. (In fact, I estimate that Lin's will actually weigh less in the end.) As you may recall from my much-vaunted (solely by myself, lol :D Mass.Is.Everything. post, increased mass affects literally everything about the engineering of such a design. Its a cascading type of effect.

>Plus, with a doll sized robot, you have unique challenges, like trying to fit all the electronics in it, let alone an AI.
Ahh. The old Miniaturization Tax! :^)
Yes, I'm aware of those volume-oriented challenges, Anon. That post's previous >pic-related of Sumomo was simply for the benefit of Anons who may not be aware of her character from Chobits. The real Sumomo robodaughteru is at least 5 or 6 times (probably double that; closer to 10 or 12 times) the volume that character would be if she were in the realworld (about like the volume/mass of a fullsized, hefty tablet today - for the fictional mango/animu character, I mean).
The target height for the project is between 18in/45cm - 24in/60cm, and I think it likely we'll meet that goal. The mass should be no more than about ~20lbs/10kgs - 30lbs/15kgs -ish, fully-loaded. That's a little more iffy at this point than the height. It depends on the density of the Li-ion (or other type) batteries, and whether we can spin highly-custom actuators for her (saving mass in the process). We'll see how it works out.
But regardless, a Sumomo-scale prototyping effort will be far less costly, and far more doable than tackling a lifesized robowaifu system right out of the gate, I deem (cf. Gall's Law [1]). Then we can focus on the bigger waifu projects. And once we all have a full productive business humming along putting out robowaifus/kits, then we can put our heads together about things like marginal costs, and begin to really drive the prices down on fullsized opensauce robowaifus for Anons & Joe Sixpacks!
We can have a special display case for dear Sumomo-chan+Buckey out in the lobby -- showcasing our first realworld models. Cheers, Anon. :^)
