Design and Implementation of UAV Obstacle Avoidance System

Aiming at the obstacle avoidance problem of UAV, a control method of UAV obstacle avoidance based on ultrasonic is proposed. The number of ultrasonic waves is increased to surround a circle based on the traditional ultrasonic obstacle avoidance scheme, and fused the information of multiple ultrasonic sensors, and according to the distance between the UAV and the obstacle and the channel value of the tele controller, the obstacle avoidance flight of the multi-rotor UAV is realized. The experimental results show that the system has the characteristics of low price, simple implementation and reliable security performance, and has a certain reference value.
