This thesis presents a standardized autonomy-to-flight-controller interface framework designed to support the integration, testing, and evaluation of advanced autonomous behaviors on research UAS platforms. The framework, referred to as ”Jacob’s Ladder,” establishes a modular architecture that separates high-level autonomy functions from low-level flight control while providing a unified communication protocol between the two layers.

A complete development and validation pipeline was implemented using Gazebo softwarein-the-loop (SITL) simulation, hardware-in-the-loop (HITL) bench testing, and real-world flight experiments. The architecture was deployed on a companion-computer configuration consisting of an NVIDIA Jetson Orin Nano and a Pixhawk Cube Orange Plus flight controller, selected for their compatibility with open-source flight software and NDAA-compliant research platforms. Autonomous mission behaviors were first validated in simulation and bench testing, and were subsequently demonstrated in flight through basic visual navigation tasks in which the aircraft detected and navigated toward a target using onboard perception and autonomy software. The results confirm that the proposed framework provides a robust and portable method for integrating autonomy algorithms with research aircraft while reducing system-integration overhead and improving reproducibility across institutions.
