Rough Sketch

Here is a rough sketch of what the catapult will look like.
The baseboard and large arms will be made of construction wood bought from Lowes.
Laser-cut acrylic sheets and 3D-printed parts will make up the mounts for the servos and hinges used in the assembly.
The controls for the 3 servos will come from the potentiometers and push button switch included in our Arduino kits.
