Materials

We thought the rectangular aluminum tubing would make the chassis stronger and easier to put together.

Machines

These are the many machines we plan to use to create our go-kart.

Prototyping

Steering Wheel Cap

Our first two tries at making this cap did not go as planned. The first one printed as two separate pieces and was not strong. The second one did not have the correct infill which caused it to break easily. On the third try we finally got it!

T Brace

T Brace prototype I made for our crossbeams.

Assembly

Chassis

This is the base shape of our chassis. As we continued to work on the project, we added more cross beams and plates where needed.

Problems

While building the chassis, we had many problems with our brackets. The brackets we used had irregular holes that were slightly off-set and asymmetric. This made drilling hard because there was an odd pattern causing us to redo bars multiple times.

Back Axle On!

We attached the back axle and I tried sitting in it to find where we could put our steering system.

Front Wheels

Chair Bolted

Steering System

Our first problem was that the given parts for our turning mechanism were too long so we had to create our own. We also had difficulty welding this system but we were able to complete it and it works!

Drive and Brake

Both of these systems were not perfect, but we got them to function in time.

Fully Assembled!

We finally got the entire kart assembled and at the moment it works, but we will continue to work on it.

Problem Solving

Differential Drive

After many test drives, everyone agreed one of the largest issues was the turning radius. In an attempt to solve this issue, I decided to make a differential driving system, so the wheel not attached to the motor could spin freely. I mimicked the hub we had already been given and changed it a little and cut it out of steel.Â
