Simple Four - Rotor Obstacle Avoidance Design based on Ultrasonic Wave
Yang Yu, Min Hui Xu · IOP Conference Series Earth and Environmental Science · 2018
The design and implementation of a simple four-axis obstacle avoidance system based on STM32F4 equipped with a steering gear and ultrasonic wave is introduced. It is mainly used to solve the problem of possible impact due to wrong manual operation. With the increasing popularity of the unmanned aerial vehicle (UAV) consumer market and the low threshold of UAV use, many people can purchase and use UAV without professional training. The safety issues of using the UAV should not be underestimated. UAV avoidance has become an urgent problem for the UAV to go to mass market.
