I made this animatronic fursuit 2005 - this is the most complex fursuit-head I ever made and the first time that I made the fur completely detachable.

There are 10 servo-motors and two battery-packs inside the head. The servos are controlled by a pic-microcontroller that's connected to my laptop. Furvan made the board for the microcontroller and programmed it, I wrote the pc-software. The hardware is designed to be able to control up to 12 servos simultaneously.

I've never trimmed the fur (because I liked it this way) - so some of the animatronic effects are barely visible.
