Contents I. Introduction
Recently, Quadrotor is considered as a robotic system which has been studied in some researches, [1]–[4]. In 1907, Quadrotor has been introduced by Breguet-Richet (Gyroplane No.1). Also, it is reported that they have lifted into the fight, [5]. The control of a quadrotor is accomplished by independently regulating the speed of each rotor. This Design of system is particularly suitable for small UAVs, because it reduces of mechanical convolution of rotor and simplifies the control algorithms [6]. Actually, the Unmanned Aerial Vehicles (UAVs) are usually used for civilian and military applications such as, surveillance, patrolling for forest fires, traffic monitoring and rescue whereas the pilot risks are frequently high. Moreover, military applications are presently considered as the lion's part of the UAV market, and this industrial usage is strongly growing. Also, unmanned flying robot can be also profited in outdoor and indoor goals. In addition, they can work in dangerous situation which is hard to work for operators, [6]. To this end, these robots are lately increased the researcher and academician societies interest, and this robot is used for many applications. The research on aerial robotics can be also continued by the Quadrotors as a usual vehicle in some implementations such as nonlinear and linear controllers, [7]–[10], the software and hardware studying, [11]–[12], and Simultaneous Localization And Mapping (SLAM), [13]–[14].
