Multi-purpose, compact unmanned aerial vehicles have been gaining remarkable capabilities in the last decades. They are important due to their abilities to replace manned aircrafts in many routine and dangerous missions, and to reduce costs of many aerial operations. These aerial robots can be utilized in a variety of civilian missions such as surveillance in disasters, traffic monitoring, law enforcement and power line maintenance. They are already being benefitted in military applications such as intelligence, surveillance, target acquisition, reconnaissance and aerial attacks. These application areas lead to more advanced research for increasing the level of autonomy and reducing the size of UAVs. UAVs can be classified into three main categories: fixed-wing UAVs, rotary-wing UAVs, and hybrid design UAVs.
