Obstacle Avoidance System Design Based on Quad - Rotor UAV

Abstract

In order to improve the safety and applicability of the quad-rotor UAV, this paper designs an obstacle avoidance system of UAV in six directions, front, back, right, left, top and bottom. The system is composed of Arduino controller with ATmega2560 as the main control chip and US-016 ultrasonic sensor. Firstly, the distance between the UAV and the sensor is measured by the ultrasonic sensor, and then the channel value of the remote control is calculated and reconstructed by the controller to realize the autonomous obstacle avoidance of the UAV. The results show that this obstacle avoidance system has the characteristics of low cost, high precision, safety and reliability, and has certain value in the application and research field of UAV.
