This is an archive of the various parts used for our cornerstone final project. We were tasked with creating a functional catapult prototype to deliver life-saving medical supplies (ping-pong balls). This catapult was meant to be capable of fully autonomous firing and reloading. It would then be mounted on a robot car that must autonomously navigate a course and, at the end, fire the catapult into a basket. Our team placed first out of roughly 70 teams at our university. 

This post is not meant as a guide to create a catapult of your own, but as a point of inspiration for future projects! Though if you do want to try making this on your own, it is up to you.
