Problem Statement

The objective of this project is to create a machine that has the capability to pour Petri dishes. The usage of this machine must be easier than simply performing the task by hand, be automated, capable of producing 120 plates per hour, be sterile, prevent the plates from sloshing, fit in a fume hood, and stack the plates while they are cooling so that they may cool properly. This all was accomplished with a device that drops the plates vertically down, fills them, and then lowers them into storage thanks to their now increased mass and a spring-loaded platform.
