“…Since the quadcopter is classified as unmanned aerial vehicle (UAV), it is believed that by the increasing demand for autonomous UAVs, quadcopters are going to be developed in autonomous control system. In the last decade, due to the military and security reasons many attempts had been conducted related to this issue [1,2,3].These days, the quadcopter is taken into consideration by many of the robotic researchers regarding its complicated structure. Regarding their complicate structure, the quadcopter is these days taken into consideration by many of the robotics researches and its complication causes special abilities which can be used in broad range of usages [4,5].Quadcopter unmanned aerial vehicles (UAV) are used for supervision and reconnaissance by military and law enforcement agencies, as well as search and rescue missions in urban environments, which is a small UAV that can quietly hover in place and use camera to tracking people on the ground.…”
