Modelo 3D Cornerstone Catapult Project (Archive) por Benedict Roberto no Printables

Descrição

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.
