GO KART PROJECT JORDAN PERKINS

Problem Statement

Problem statement: Our problem statement is how can we design, build, and test a drill powered go-kart that will be competing on three different courses given only 2 marking periods, a budget of $25 , and limited materials (18V Drill , 1 sheet of ¾” plywood,Miscellaneous hardware , and Wood Glue.

Research

Research: The drill will power the go kart by being in a mechanism that is connected to a bike chain. This connection will be by extension as the connected drill will be attached to an extended bike chain. This design can work very well as this design imitates an actual bike chain.

Research: This is a picture of a brake similar to what we want out brake to look like. Instead of ours being metal it will be made out of wood and will be on the side of the go cart with the wheel that isn't drill powered.

Research: Here is an updated picture of what our braking system will look like. The wood block shown in the image above will be applied to both wheels on the back of the go kart. They will each be connected to a string that the driver will pull to activate the breaking system.

Design

Sketch of Body

Design:This is an image of how we want the base of our go cart to look like. The back right wheel is where we will connect the the drill. The front of the base will be around 51 inches and and the back of the base will be around 60 inches

Steering wheel (Rough sketch)
Sketch of steering

Steering Wheel Updated: Here is an updated sketch version of our steering wheel. This sketch has more accurate dimensions. The steering wheel will have two strings connected to it. The string will run through a”I” bolt keeping the string together and connect to the two wheels(one string to each wheel). When we turn the steering wheel in one direction one wheel will turn with the steering wheel allowing slack for the other wheel to turn the opposite direction.

Electronics: Below is a screenshot/photo of our electronic box . This box will be attached to our go kart and will most likely contain a speaker.

Design: This is a "3D Cad" model of our body assembled. This is just the body so we still have to add the wheels (which will be added to the left and right of the seat), the braking system ( attached to each wheel in the back of the go cart) , steering (middle of go cart), Electronics (headlights, and horn) and the throttle.

Build

Build: This is a picture of our body cut out and assembled.We till have a lot of things to add including the wheels , braking system , electronics, etc.

Photo of Tommy Assembling the chair to the body

Build: This is the back of our assembled go cart body. We added a piece of wood to the back of our body so when our driver sits in the go cart, against the seat ,it just won't bend back and break.

Wheels being stabilized
Solution to bent axle

Build:Wheels:For our wheels we used two .5 inch thick axles for the front and back wheels. When adding the wheels to the axles we realized that one of them was slightly bent. We came up with a solution by adding bolt to the middle of the axle where it was bent. We then added the wheels to the base and screwed a piece of wood to the bottom of it for more support.

Steering wheel added to the body
Spray painted pvc pipe for steering wheel

Build: Steering: To start the steering we drilled a 1 inch hole 3 feet and 1.5 feet in the base to accommodate the PVC pipe. Then we spray painted the PVC green and the head of the steering wheel yellow. Then we assembled the head of the steering wheel to the pipe using the Instamorph.
