Path Planning Method for Collision Avoidance of Multiple UAVs

In recent years, the development of unmanned aerial vehicles (UAVs) has increased significantly and they are currently used in various fields and applications. In some applications, multiple UAVs need to be cooperated to accomplish tasks, because a single UAV is not sufficient. However, even when multiple UAVs are used, their autonomous control systems are not perfect, which leads to collisions between the UAVs. In this paper, we propose a path planning method for collision avoidance of UAVs, when multiple UAVs are controlled using a ground control system. Furthermore, using this method, the UAVs have less likelihood to be in a close encounter with obstacles, and collisions are avoided.
