Machine Learning for UAV Propeller Fault Detection based on a Hybrid Data Generation Model

no code implementations • 3 Feb 2023 • J. J. Tong, W. Zhang, F. Liao, C. F. Li, Y. F. Zhang

This paper describes the development of an on-board data-driven system that can monitor and localize the fault in a quadrotor unmanned aerial vehicle (UAV) and at the same time, evaluate the degree of damage of the fault under real scenarios.
