Well, I wanted to use some very small servos for a project and the smallest I could find there these: https://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=33401
But Danny Choo (a Japanese blogger) started a business with robotic dolls some time ago and I remember him mentioning somewhere on his site that he uses servos in his dolls.

This is about 60cm in height and therefore the servo in my first link is obviously too big, to e.g. fit inside the arm.
I was wondering what kind of servo(or motor in general if it's not a servo in the end) he is using that is so tiny it can fit in there.
Does anyone here have any idea?
