Robotic head for robotic enthusiasts

Similar projects worth following
rEmotion is a project aimed at creating a 3D-printed robotic head capable of displaying a wide range of facial expressions. This project is designed to be an accessible and easy-to-develop platform for makers, educators, and hobbyists. By utilizing simple 3D printing models and commercially off-the-shelf (COTS) components, rEmotion ensures that anyone with basic electronics and 3D printing knowledge can build and customize their own robotic head, and then extend it to build a really unique robot.

The project comes with two extensions:
- web camera module
- step motor that can turn the head around
