I created this animatronic eye for a friend doing a custom latex mask for cosplay. It uses standard 9g servo (tower pro, etc) to create a realistic moving eye ball effect.

Post-Printing

I used an Arduino pro mini and wrote a simple program that sweeps the servo 30 degrees at random angles and delays. Then wired a small contact switch so the wearer can activate it, There's an LED behind the iris to make it glow, We filled the iris with an epoxy and painted it to match the contacts.
