Research of Four-axis Aircraft Using WIFI and Rotary Anti-collision System

摘要

In recent years, Unmanned aerial vehicles (UAVs) have become increasingly important in the fields of industry, agriculture, detection and logistics; the scientific research of UAVs has begun to cover more extensive fields. However, during the execution of the mission, a collision may result in property loss or even a threat to personal safety in case obstacles can't be avoided in time. Therefore, the anti-collision function is vital to the UAV during flight. In order to ensure that the UAV can fly more stably, safely and can timely response, this paper proposed a set of four-axis aircraft which includes Arduino micro-controller, rotary anti-collision ultrasonic and the mobile WIFI control system. This system can detect surrounding obstacles and combine with the corresponding signal lights on the aircraft which can shows different colors to prompt the best optimal direction of the next flight, so as to enable the ground control station (GCS) to receive feedback information and make emergency treatment in time.
