Escarrot and Disco Carrot

We made a carrot that moves its legs when it detects light.

We told a story for the exhibition about two sentient carrots that ran away during our process of experimenting with it, encouraging the guests to go and look for the carrots. The guests would then follow the sound of distant music into the basement where they would find the carrots dancing in a disco club.

The carrots were build using two motors that both triggers when they senses light. The disco carrot spins in circles and the other carrot moves its legs.

We used a lazer cutter and 3D printer. 

3D printed: We printed the gears and body for the carrot moving its legs and the disco ball.

Lazer cut: We cut wheels and wagon for the Escarrot. For the disco we cut the support for the motor and the stage 

black paint

For the elctorins we use:

Power supply

Arduino

Lightsenser attached to arduino

Motor shield

Wires

We started printing 3D gear which took 15 hours. Then we took the support of and put it together.

We attached the motor to the gear and used a battery pack to make sure that everything was working. It wasn't enough power though so we plugged it into the wall.

We designed a few extra parts for the gear so it would balance and be able to hold the weight of a carrot.

Next was to make the light sensor work.

We received instructions from this website https://arduinogetstarted.com/tutorials/arduino-light-sensor

The website explains very well how to apply it to arduino.

Then all that was left was to do some touch ups(for example sand papering and glueing loose parts together) so that everything would run smoothly.

First was making a box for the carriage that I made on the website www.makercase.com

We the stage for the disco carrot in the same website.

We used a resin printer for the glasses on the disco carrot.

We painted everything black and then glued it together using wood glue.

For the disco ball, we 3d printed a ball and then glued a mirror on it. We used the laser cutter to break the mirror safely.

Then everything was ready!

Here are some videos!
