ECE477 Final Review: Team #1: Project Dada

Outline Project Overview Block Diagram Design Challenges Individual Contributions Project Demonstration Questions

Project Overview Project DADA aims to provide aid workers in disaster zones with the tools to perform search-and-rescue missions autonomously and aerially. Worst parts of disaster sites are often dangerous for people/intractable for ground vehicles An aerial route is needed in certain situations Autonomous control enables aid workers to perform critical tasks while the aerial mission is completed in parallel Project also pushes a novel concept of modular quadcopters Different payloads containing different sensors and other mission hardware allow for greater system versatility

Project Demonstration An ability to monitor battery state for charging and notifying when battery capacity is low. An ability to program a flight plan of waypoints via an offboard GUI. An ability to autonomously control the flight controller via a master microcontroller using PWM. An ability to receive flight plan data in the payload microcontroller and transfer to the master microcontroller via SPI. An ability to demonstrate the interchangeability between at least two distinct payloads integrated through common power and communication lines, respectively.
