Autopilot programming and operations within an unmanned aerial systems course


Students majoring in Unmanned Aerial Systems (UAS), commonly known as drones, are expected to have a diverse background of hands-on and theoretical skills.


Since the UAS industry is rapidly growing at approximately 30% per year, quality graduates are in high demand. A junior level course on autonomous aerial vehicles has been created to provide this blend of these essential skills required by the UAS industry.


Concepts related to navigation, control, regulations, guidance, airspace, and autopilot programming are introduced during the twice weekly, one-hour lecture. These topics are reinforced during a once weekly, two-hour laboratory where students in groups of two work during the first third of a fifteen-week semester to integrate an open source, open hardware autopilot into a 3d Printed Quadcopter.

The second third of the semester involves students flight testing their vehicle in outdoor conditions and obtaining real-time telemetry for post flight review. The final third of the semester requires students to fly a simulated package delivery mission where the quadcopter auto takes off, navigates through a series of waypoints, auto lands on a target, and finally returns to launch. The vehicle must fly the entire missions without human interaction.

By combining both hand-on and theoretical skills, students who complete this course have a valuable skillset which is in high demand by the UAS industry.

Emerging Threats: Cyber-Physical Attacks on Additive Manufactured UAV Parts


Additive Manufacturing (AM, or 3D printing) is an emerging manufacturing technology with far-reaching implications: AM is increasingly used to produce functional parts, including components for safety-critical systems, but its unique capabilities and dependence on computerization raise a concern that an AM generated part could be sabotaged by a cyber-physical attack.

In this paper, it is demonstrated the validity of this concern by presenting a novel attack: reducing the fatigue life of a 3D-printed quadcopter propeller, causing its mid-flight failure, ultimately leading to the quadcopter’s fall and destruction.
