In this tutorial I will show you two simple methods for building a believable robotic mouth. One articulated and moveable, the other an LCD flashing design. Both animatronic mouth designs create a believable illusion for your animatronic robot and can be built on a modest DIY budget.
Purpose & Overview of this project
This tutorial aims to create two different styles of robotic mouths. The first robotic mouth should be a mouth that moves up and down being articulated by a servo motor actuator. The second design will consist of an LCD display with high power backlight that can be switched on and off. Both designs create an illusion of a mouth moving as it speaks.
Once built, the software for controlling either the servo motor movement or LCD backlight flashes should be easy to sync with spoken words, which will be demonstrated in a short video in the data section of this tutorial. The articulated animatronic mouth will be added to the animatronic face from the two tutorials: Animatronic Eyebrows and Animatronic Eyes. The LCD mouth will be built on a mock-up face for demonstration.
