Abstract: An unmanned aerial vehicle (UAV) navigation obstacle avoidance system and method thereof are introduced. The UAV navigation obstacle avoidance system provides with functions of automatically controlling the UAV motive power sources to control the flight of UAV and avoid the obstacle. The system comprises a sensing device, a signal processing module, a communication module, a control module. The sensing device detects the relative direction, velocity and distance between a UAV and a dynamic or static obstacle. The sensing device also detects the real-time position, flight attitude and inertia signals of the UAV. The signal processing module generates a UAV flight control signal. The control module receives the UAV flight control signal and controls each of the UAV motive power sources. Therefore, the system achieves the purpose of controlling flight and obstacle avoidance and forward to the original planned follow-on flight route after the avoidance.
