The Study of Using Arduino to Control Aircraft Combined with Obstacle Avoidance Warning Function

With the rapid development of UAV technology, more and more sophisticated and simple unmanned aerial vehicles have been brought to market. For the general public however the issue of greatest concern has always been security. At present, it is a key issue for UAV development to realize air safety flight, and the obstacle avoidance function plays a key role in this issue. This thesis adopted the Arduino UNO, rotary ultrasonic, three color light and buzzer as performance of obstacle avoidance warning system, and send warning signals to the mobile phone APP through the WIFI to remind staff operating in advance to avoid an obstruction on the flight path, greatly reduce various kind of harm for error, etc.
