Jim Leemhuis, AKA JimScubba2386 posted a video series on how to make a programmable animatronic eyeball mechanism using 3D printed parts, micro-controllers and servos. He also posted his 3D files along with a parts list and notes on his Thingiverse page.
This project allows you to build a pair of animatronic eyes that can be programmed via puppetry and played back to you as much as you want. Here is a quick demo of how it works: https://twitter.com/JimScuba2386/status/965712794925633536
Jim put together 6 videos that covers the project and breakdowns the assembly, construction and code. Jim used an Adafruit Feather and Feather Servo Wing as the brains.
It seems like a very ambitious project (and it is) but Jim thoroughly explains how to build it. If you’re a Disney fan and interested in building Animatronics, check out Jim’s video series. This is a great example of how to capture movements, play them back and puppeteer several servos.
Here are the parts used:
