My main responsibility in this project was designing and building the electronics that made sample collection possible. The system is built around an Arduino Uno and also uses servos, a peristaltic pump, an H-bridge, various water quality sensors, and an SD card reader. I was also responsible for manufacturing and some CAD work (NX), I 3D printed our design on my personal 3D printer and the results were great. A personal goal for this project was to use exclusively open source technology, I was able to achieve this and all of the CAD files and code is on Github: https://github.com/fx0641/Drone-for-Collecting-Water-Samples

 

The main challenges of this project were to have a working prototype with a budget under $500, keeping the design light weight and balanced to mitigate affects on flight, and to have the mechatronic system interact directly with water.
