I drink a lot of coffee, and I thought the steam going up and down would mimic the actual motion nicely.

What it does

As the axle turns, the cam shaft causes the steam to rise and fall behind the coffee cup.

How we built it

Most of the components were made with the laser cutter. The caps were made with 3D printed caps to allow for the axle to be turned easily. A medal rod was used as the axle because it was easier t work with than the wider alternatives.

Challenges we ran into

The initial cam constructed did not work well with the steam because it angled the component to the back of the box. As a result, the laser cut cam was replaced with a cardboard one. This worked much bette that the initial cam because the cardboard was more malleable and easier to work with.

Accomplishments that we're proud of

It may not be the cleanest rotation, but the steam does rise and fall.

What we learned

I learned how to use SolidWorks for this project (which I had never used before this course). I also learned what an automata is and how to construct one. Basically, all the concepts of the project were new to me.

What's next for Coffee Cup Automata

I would like to laser cut the cardboard shape of the cam to create a more permanent design.
