Doll motion, like moving legs and etc

[max-kub]

Hi
Had anybody thought about installing servos into doll's joints and make her move?
I think there should be some powerful servos which could lift a doll

Sure have, what are your thoughts on the control circuits, for internalization but also maintainability?

Some redesign of the servo joint to chassis interfaces are also required due to shifting load vector moments at fluid joint angle transitions as well.

Use arduino platform for writing code, I think it could be written adjustable for changing the speed and the height of motion and make an app for smartphone, maybe the easiest will be smt like horse riding position so motion will start here)

About maintaining.....I don't se problems here put arduino and some other electronic in head and neck to provide it protection from water during cleaning
Make plug between neck and head electronic somewhere near the neck to disassemble the head
Make power plug somewhere on the back side of the neck or just put the long wire go away to the circuit
Maybe sometime it could be powered by battery)

The servos and joints...
Found some
I think for the start and prototypes it should be just welded to the bones, cut joints and weld it in their places)

Now I need to look for another one doll to make tests on it)
I'm really got interested while I was thinking abou and writing this post

If you wanted some repetitious hip movement for such things as cowgirl or doggy style you could probably just use a small variable speed DC motor and a rechargeable battery pack.
