A Common Obstacle Avoidance Module Based on Fuzzy Algorithm for Unmanned Aerial Vehicle

A common UAV(Unmanned Aerial Vehicle)'s collision avoidance module was introduced in this paper to handle the flight safety of the UAV. Some ultrasonic sensors were used to collect the obstacle's distance and direction information in real time. The fuzzy algorithm was used to plan a new obstacle avoidance path based on the information. By taking over the control right of the flight controller and sending it the new movement commands, the module would allow the UAV to finish the obstacle avoidance task. During the process, any modification on the original codes of the flight controller was not needed. The MATLAB simulations and experiments verified the effectiveness of the common UAV's collision avoidance module.
