Head Design

faceanimation.mp4

Animatronics

The head prototype consisted of two main design features. Notably, the head was designed with a "quick-disconnect" neck that would allow the head to be removed and attached quickly. Additionally, the facial expressions are achieved through pneumatic actuators and servos that rotate eyebrows and a mustache in the shape of the lumberjack. To the left is a video displaying the 3D modeling of the animatronics.

Quick Disconect

The left image displays a 3D model of the neck. The neck was designed with modularity in mind with the thought that multiple heads might be created in the future and the neck allows for quick replacements and maintenance.

Initial Wiring Problems

The initial prototyping phase was not perfect. Problems we experienced were a blown regulator, troubleshooting to a DC power source, and then low quality servos.

Electronic Solution

In order to solve the electrical issues we grounded our Arduino board, utilized a bigger battery, and purchased higher quality servos which reduces our issues significantly.
