A Study on a Flight Safe System in Unmanned Aerial Vehicles

摘要

Recently, as the interest of unmanned aerial vehicles has increased, technological development of the drone has been progressing. Emergency situations can occur due to various environmental variables such as sudden loss of connection between flight and controller, instability caused by strong wind during the flight, and the lack of power supply between drone components. In this paper, we design and fabricate a drone based on a pixhawk FCC (flight control computers) with F450 class frame. The implemented drone aims to land safely back to the take-off point based on GPS when a fail safe mode is activated. The fail safe mode was applied to the situation where the connection between drone and the controller was suddenly disconnected. We tested an accuracy of the fail safe mode in fixhawk FCC.
