The multi-rotor unmanned aerial vehicles (UAVs) is a small vertical take-off and landing aircraft with three or more rotor shafts, which is gradually applied in various fields due to its stable structure. However, in order to improve the safety of multi-rotor UAVs, it is required to avoid uncertain obstacles by themselves during the flight. This paper analyses the sensors, the detection methods of obstacles and algorithms for automatic obstacle avoidance. Finally, the key issues and prospects of autonomous obstacle avoidance technology of the multi-rotor UAVs are also described. Compared with the previous related articles, this paper makes a detailed investigation on several parts of the obstacle avoidance process, especially lists several major obstacle avoidance algorithms.
