Taking Flight with Dialogue: Enabling Natural Language Control for PX4-based Drone Agent (2506.07509v1)

Abstract: Recent advances in agentic and physical AI have largely focused on ground-based platforms such as humanoid and wheeled robots, leaving aerial robots relatively underexplored. Meanwhile, state-of-the-art unmanned aerial vehicle (UAV) multimodal vision-language systems typically rely on closed-source models accessible only to well-resourced organizations. To democratize natural language control of autonomous drones, we present an open-source agentic framework that integrates PX4-based flight control, Robot Operating System 2 (ROS 2) middleware, and locally hosted models using Ollama. We evaluate performance both in simulation and on a custom quadcopter platform, benchmarking four LLM families for command generation and three vision-LLM (VLM) families for scene understanding.
