Building Our Go Kart By Lauren Naumann


This was the original design that we were imaging for our go kart. We were trying to make a go kart that was not too complicated, but included the necessary parts to have the kart work to the best of its ability. We want to use the rope as braking and steering, as seen in the picture.

Body Design

This sketch was one of our very first ideas we put together as a group to imagine what the kart would look like in each part. We tried to measure where we were putting our parts and the dimensions of them. This sketch almost matched our original design idea, but we changed a few parts.


This is evidence of our electronics planning. We are going to create turn signals to add to the front using the arduino, along with a horn and speakers. We want to be able to play music and have a working horn on the steering wheel.


Here we have taken apart a bike in the hopes to use the brakes for our kart. We are attaching the brake to the rear wheels with this mechanism from the bike and hoping that rear braking will work best. This will be a hand brake and will be attached to the steering wheel once assembled.

Motor Drive

The first photo exhibits the design for OnShape that is going to hold the drill in place. This mortise and tenon design will allow the piece to snap into the base to hold the drill and then unclip when the drill needs to be removed. This idea is similar to the one shown in the bottom picture, only a piece of wood will be used instead of a metal clip. As shown in the bottom picture, we will be using a gear to turn the wheel that we are obtaining from a bike.


This piece of wood is being lathed in order to be used as an axel for the front tires. We are planning to have rope attached to the axel and the steering wheel as our steering mechanism.


Our throttle is going to be like our hand brake, except it will accelerate the vehicle. We took a hand brake from a bike and are going to attach it to drill in order to power the machine. When the throttle is pressed, the drill will spin and the car will be accelerated.

OnShape Design

This was my design to hold the drill in place. The mortise and tenon will snap into the base to hold the drill and easily come back out. The challenge is going to be making sure the mortise and tenon is accurate for both the base and this design. If the measurements become messed up in the process, the design will not work and the drill will have no way of being held in place during assembly.

ShopBot Body

We successfully ShopBotted our body and are ready to start adding the other parts to the body. We have other pieces that are shopbotted that have not been put on yet, but will be put on after other assembly is completed.

Body Assembly

The part we attached for the drill snapped into the body correctly and fit snugly. The drill fits into the piece and can be taken out as well.


We finished the electronics of our go kart by creating two turn signal lights and a speaker with adjustable sound. We figured out all of the coding for the three systems and put each code together to find that it all works. The last part we have to figure out is extending the wiring so we can place the speaker, knob, buttons and lights in the appropriate places on the go kart.

Back Wheels

This is the design we went for in terms of our back wheels. This wheel does not have the gear and drill attached but has the same idea. We used two blocks of wood that will be screwed on beneath the base that has a metal rod going through. The wheel will spin on the rod when the Kart is in motion.

Front Wheels

Our front wheels will turn on an axle while being attached by PVC Pipe. The front part of our base has a piece sticking out that will hold the axle once attached. The wheels will then turn when the steering wheel is turned.

Body Update

We added many pieces to our body since we had printed it out. As seen in the left picture, we have a hole and wood pieces put together in order to hold the steering wheel. We also had finished the electronics box and used velcro to hold the box on the car. As seen on the right, there is a backrest and the steering wheel was put on as well. There are still pieces that we need to add on to the body before it is completed.

Steering Update

As seen in the picture on the left, we attached our front axel to the car. The axel easily turns from left to right and all that is left to do is attach the string to the steering wheel in order to have the axel turn. As seen in the other picture, we added a rubber tire around the wheel to add a better grip to the wheel. We finished the steering with a video to demonstrate our final product.

Brakes Update

Our braking is completed on our car and is a spring system. The picture on the right shows our prototype on OnShape for how we had planned to create the system. We planned on using a spring all along, but at first did not know exactly how. Our final system ended up having a block of wood stationery on the body attached by a spring to another block of wood that is pushed into the rear tire to stop the car.

Electronics Update

We finished our electronic box and code and everything worked well. We soldered the buttons and the LEDs to longer wires in order to make the control box work. We then attached the LEDs up the back of the backrest to imitate turn signals. Each button in the box controls one of the LEDs and the potentiometer controls the volume of the piezo speaker in the control box. The box is attached by Velcro so it can be taken off and put back on.
