I've always been excited about new technologies and the way science has facilitated the lives of human beings. As far as I remember I had a great passion for two fields of knowledge. One related to flying vehicles and the other one concerning energy administration. I found myself eager about the science behind building and controlling machines that fly. Whether it is an airplane or a small flying robot. On the other hand, my interest in energy and the way it can be managed and conducted motivated me to take several courses relating to energy conduction during my B.Sc. education. During and after my education, I've had pretty good chances to get involved in designing and building a few numbers of aerial robots and drones with diverse applications. My field of interests and experience covers automation, control, design, dynamic simulation, system modeling of flying machines and robots and energy conductors. In this website, you can find some projects which I've had the opportunity to be a part of them that helped me gain more experience and knowledge in mentioned fields. For further information please send me a message in contact section.

In this paper, we consider the problem of con- trolling multiple quadrotors fastened to a payload and cooperatively transport it in 3 dimensions. We model the quadrotors as a group rigidly attached to a payload. Then we develop the equations of motion of this rigid system. We propose a rigid-body formation system controller based on LQR method as well as a Paparazzi-based guidance scheme for the payload mission trajectory. Also a PD controller is developed and its results are compared with the main controller's results. A simulation study with two quadrotors cooperatively stabilizing, and transporting a payload along two differ- ent desired three-dimensional trajectories is presented.
