Abstract
An unmanned aerial vehicle and a fail-safe method thereof are provided. The unmanned aerial vehicle includes at least one actuator, a failure processing circuit, and a flight controller. The actuator is configured to drive the flight behavior of the unmanned aerial vehicle. The failure processing circuit is configured to: define a corresponding relationship between the multiple failure states and the multiple protection measures, wherein each protection measure is respectively defined with a priority level and each protection measure is used to correspondingly change the flight behavior of the unmanned aerial vehicle; determine multiple current failure states when the flight behavior takes place; and select, according to the corresponding relationship, the selected protection measure having the highest priority level among the protection measures corresponding to the current failure state. The flight controller is used to change the flight behavior of the unmanned aerial vehicle according to the selected protection measures.
