This project, sponsored by Masimo, aimed to create a standardized testing system for chemical resistance on medical monitoring products. It employs a fluid delivery mechanism for cleaning agents followed by wipes under constant pressure. Controlled through a touch-screen panel, it regulates parameters such as speed and cycles, equipped with a camera for progress monitoring and memory for test recall. The user can adjust parameters like wipes, cycle intervals, fluid volume, and duration.

In support of Cibus US LLC, an agricultural trait development company, Team Wells Pourgo worked to automate the filling of one-well Petri dishes with plant culture medium. Custom mechanisms were designed and tested to carefully relay the plates through the process. The system can de-stack, fill, and cool the plates before restacking them for packaging. Full autonomy is achieved using object sensors to trigger events and stepper motors for actuation. A safety controller monitors e-stop buttons and manages power to the motors.

The objective of this project is to design a nature-inspired wind turbine to improve energy capture efficiency and durability. Most turbines turn in wind, and when wind speeds exceed 50 mph, the wind turbine automatically shuts off for safety. To address this, the team designed a horizontal axis wind turbine inspired by the behavior of palm fronds. The blades are mounted to the turbine on bases made of a flexible material that bends inward with increasing wind speeds, improving durability
and maintaining functionality.
