My Final Project

First approach

The project is based on designing an animatronic that helps with " childhood apraxia of speech (CAS). "
The goal is for patients to imitate the facial movements of the animatronic when speaking, helping them with the placement of lips and mouth.
Below are the first sketches of the project.
