Surveillance MAV Project Road Map - Senior Design I & II

This project aims to design and build a surveillance Micro Aerial Vehicle (MAV) that can fly up to 1.2 kilometers, capture clear photos, and be controlled remotely. The roadmap includes research, materials analysis, wing development, propulsion integration, and testing. The objectives include stability, endurance, connectivity, and manufacturability.
