The steering will consist of a lever that moves a plank of wood and then the front axel containing the tires, such as in the picture.
The front axel will have a rod that spans the length of the wood. The whole plank of wood, connecting two tires, will rotate from the middle point when turned with the lever.
The throttle will be controlled by a pedal. A string will be attached that runs the length of the body and pulls on the trigger of the drill. A wood casing will keep the string in place.
We made a list of materials we would need and how many we would need of each.
