Goofy Eyes

This project has been built in the context of a rapid prototyping class.

The aim of our project is to create robotic eyes capable of tracking an object placed in front of them using an infrared sensor.

The main requirement is that the eyes track the closest object to the sensor.

Supplies

CAO on Catia

We designed the 3D models of the eyeballs using Catia V5, as well as the parts used to attach the servomotors to the eyes.

Here is the result of the 3D printing: the eyeballs are assembled with the adapters.

Box With Laser Cutter

We made our box from a 6mm sheet to make it stronger. The notches on the top measure 3mm, which is the thickness of the plexiglass that forms our lid.

Adafruit was useless, so we had to do everything on our own like grown-ups. On top of that, we were greatly disappointed because we thought the motor would rotate 360 degrees, but alas! It only rotated 180 degrees. As a result, we had to abandon our owl project.

Wire Circuit

What you're looking at is state of the art pinning & electro-teching. Ground & alimentation have been condensed to a single line on the board to minimise the use of copper. The exiting flow of energy and data is alternating between motors and TOF-distance captors.

Look at this beautiful result !

Challenges

We encountered a few problems:

  1. After cutting a new 3mm box, we realized it was not strong enough and could not hold itself together. Therefore, we decided to use nails to reinforce it. However, we overlooked one of the requirements, which was that the creation had to be fully disassemblable, making it difficult to achieve with nails. As a result, we decided to redo another cutting session using 6mm material.
  2. During the cutting of the box, we used a 5mm sheet, while the intended notches were 3mm. The sheets did not fit together properly, so we had to redo the cutting with a 3mm sheet.
  3. Another issue concerned the eyes: the hole designed for the sensor was too small, which would have hindered proper detection. To save resources, we chose not to reprint the eyes. Instead, we used a drill to enlarge the holes. The final result may not feature doe-like eyes, but we did our best to ensure that the gaze would still melt your heart!
