Design, build, and test a drill powered go-kart that will be competing on three different courses: Drag strip (acceleration/top speed), road course (handling/control) and super mileage (endurance/efficiency). Use materials such as: one sheet of plywood, one drill, and a budget of twenty-five dollars. Build a Go-kart to support at least one hundred pounds.The Go-kart will be test and evaluated by our team by collecting data for the overall performance. This Go-Kart must be completed with all functions by the end of the fourth marking period.
This image shows another way we can use drill to possibly move the wheels. The head of the drill might offer less friction than if the drill was directly connected to the wheel. We are undecided when it comes to the final design but this is just reattach.
Our design of the steering wheel will be based off of this video and design. We will use the string tied to the pole and tied to each wheel and will turn with the steering wheel.
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.
Go kart body design is finalized in the top left corner. Have a board that is 4'x2'. On the bottom there will be four 2x4's fastened together by screws to fame a frame. This frame will give the wheels a place to screw to and lift the kart off the ground providing extra strength.
This is the final design of the steering mechanism. The design will consist of a string that is connected to a pole with a steering wheel on top. The string will also be connected to the two wheels so when the steering wheel turns so will the wheels.
Bottom left is the design of our electronics. We plan to have working turn signals and a horn. Both will be done with a Arduino and we will use code for the lights and horn
This drill trigger has a loop of string tried around it. The loop will have another string that connects to a boards next to the steering wheel. When pulling the string the loop will tighten pulling the trigger.
Bottom Right- Brake
The brake will consist of four brakes on each wheels. They are all connected on the inner side of the wheel and will each have a string. Four string combine in the middle and tied to one string that will connect up to the steering wheel. When pulled on the one string all four brakes will activate creating friction on the wheel and slowing the go kart.
This is our final design of all four major components of our go-kart. Brakes, wheels, body, and steering all are included in this Onshape document that is completed by all four of my group.
