Three-dimensional Collision Avoidance Design on Unmanned Aerial Vehicle

Recently, unmanned aerial vehicles (UAVs) are attracting growing interest due to its wide range of applications. Collision avoidance algorithm is one of the crucial issue for UAVs to autonomously handle avoidance maneuver if it encounters obstacle in the airspace. This has motivated the development of several collision avoidance algorithm. Various approach in two-dimensional and three-dimensional collision avoidance has been reported in recent years. In this paper, we design a collision avoidance algorithm for UAVs to navigate safely in the airspace. The method is designed based on the original three-dimensional velocity obstacle method.
