A research team from the Faculty of Engineering at King Khalid University, Engineering and Electrical Mechanics Disciplines completed the first phase of a scientific research project, Unmanned Aerial Vehicle, UAV. It is the stage of designs, with support from the Deanship of Scientific Research at the university.
In this regard, Dr. Tawfiq Khatab, a professor at the Faculty of Engineering, the Head of the research team on this project stated that there are many and varied researches in this area, so the development is moving at a rapid pace. He said, "Most prestigious universities pay great attention and interest to such projects in order to have a technical reference in development process. He added, "Those universities also seek to its designs and own product to be unique scientifically to teach students modern technologies in design, production and tasks development."
Khatab clarified that the research process for the project will be in three phases. Finally, we will capable of manufacturing and testing an integrated model of the UAV.
The first stage is the design, and the second phase includes manufacturing operations, which include the manufacture of the raw material (fiberglass) which will be used to make the drone, synthesis graphics, design and manufacture of the fuselage, engine assembly, control mechanism in the drone, the manufacture of wheels, manufacturing fungible wings, cover the body and the wings and then the final finishing of the drone.
The third phase is for tests and performance analysis (such as tensile test - determining Centers shear - Analysis of bends - measurements of engine thrust - Installation of useful load -connect the power source - proceeding necessary tests – plug in the connection of data transfer and remote control and making necessary tests - determine the plane center of gravity after covering the body – prepare the drone to make necessary tests and record the results - make the final report)
Khatab clarified that this model will be used as a reference to all students, and as an advanced technology that could benefit the Mechanics Discipline in graphics engineering designs for all parts, measurements of Aero Dynamics on all parts, balance measurement, center of gravity and momentum, and the weight of the useful load.
The specialization of Electrical Engineering is also useful in features of data transfer link, the autopilot , the control unit in the moving parts, in addition to the software used in the ground transmitter and receiver units, and how to control the drone remotely.
The importance of research in this area as it contains advanced scientific techniques in the field of electrical and mechanical engineering, in addition to its many uses in practical life.
Khatab confirmed that the search is scalable in terms of shape, size (only body change) and in terms of desired application to use it. He said, "The Drone often has its basic role in achieving difficult tasks, at a low cost, which It is impossible for the man to do, such as : Exploring mountainous areas with minimal effort. "
He added, "It is clear now, what is the main objective of doing such research in the design of an unmanned aerial vehicle (Mini-UAV) and equip it with air photography system that could be controlled from the ground unit."
Khatab clarified that the real academic goal of this research is purely an educational one for students, as it is the beginning of a new era for both the level and direction of students' graduation projects. He said, "This product, the UAV, will be used as a reference for students' graduation projects to be able to learn the foundations of design, manufacturing and measurements, tests and recording the results and making the technical reports properly."
Regarding the possible uses of this project in the future, he confirmed that this research will be the start of other multiple researches. Finally, the project will save the following services: photography rugged places - monitoring instantaneous events and traffic - instantaneous monitoring of the borders.

In detail, speak about your start as an inventor
The origins of my attempts in invention started when I was in the intermediate stage at school, when I became used to discovering things and tried to solve some of the problems I encountered, while making modest inventions. I loved the discovery of devices, dismantling and re-building them, and I still keep some of my old attempts.
Who supported you to improve your talent?
I used to search online for ways to show inventions in public, and finally I met the Director of the Department of Engineering, Engineer Sultan Mohammed Al Mutihan, who intensively supported me at that time and was also the main support in my getting a number of awards in this area.
What are the most important things you participated in?
In 1428-1429AH, I participated in the Abha Prize Exhibition for Higher Education, which is held under the auspices of the Prince of Asir Province, and in 1430 I represented King Khalid University in the talent tent for Saudi universities, also sponsored by the Prince of Assir Province. I also participated in the exhibition for scientific innovation at the closing ceremony of the university in 1430 AH.
I also participated in the 1st scientific competitive forum for King Khalid University students in 1432 AH, as well as the 2nd scientific competitive preparatory forum for higher education students in 1432 AH.
I represented the university in the gallery of scientific innovations of the Okaz market in Taif in 1433 AH, and in the same year, I participated at university level in the gallery of the scientific competitive preparatory forum at the 3rd Scientific Conference for students of higher education in 1433 AH.
In 1434 AH, I participated independently for the scientific research award held by the Department of Patents and Discoveries, and I represented the university in the 8th Cultural Week for universities held by the Cooperation Council (GCC) in the field of scientific innovations in 1434 AH. I also participated in the exhibitions at the 1st and 2nd scientific symposiums, which were organized by the Centre for Talent and Creativity at the university.
What are your main achievements during your study period?
I got more than 50 certificates of appreciation and excellence, and placed first and second in the Abha Prize for Higher Education in the field of scientific innovation, besides being granted honors from the Prince of Asir Prince in 1429 AH.

I have been a member of the Talent and Creativity Centre since 1430 AH, and the World Organization, IEEE, since 1431, as well as Talent Institution since 1432. I am also, thanks to Allah, a member of the Saudi Inventors Association since 1432.
Do you believe in the need to attend training courses in the field of hobbies and talent?
I believe in the need to refine talent by attending courses and specialized workshops, since there are many benefits, including courses that open up new horizons in which you may meet people and benefit from their experience.
On a personal level, I have joined various training courses, included nanotechnology, computers, robotics and automated control, new media, the formulation of ideas, research management, and the cycle of heat exchangers.
Explain some of your projects to us
The deaf are an important group in society and need care, attention and comprehensive care by inventing tools and devices that help them to live a happy, dignified life.
To contribute to help this dear group, I invented an alarm pad to help them to wake up in time in a way that suits them.
It is known that when a deaf person wants to wake up at a certain time, it would be difficult because he does not have a tool that awakens him in a way suitable for his condition as most of alarm devices in the market operate with by sound.
That's what made me think of the innovation of a pad attached to a watch and connected electrically in order to cause seismic movements to be felt by the sleeper at the given time.
For my graduation project, I studied the subject of global warming and the widening of the ozone layer, as factories, power stations, and emissions of gases are main the causes of pollution, the changes taking place on the planet, and the emergence of diseases and congenital malformations in living organisms.
In an attempt to invent something that solves this problem, I made a filter for the exhaust gases emanating from factories and refineries before being released into the air by establishing a building at back of the factory, using water desalination and steaming water and then condensing it to benefit from the heat of the flue.
Do you think that this project has succeeded in finding a solution to the problem?
I think my project is a serious attempt to solve this problem, and no one can deny that scientific innovations are built by accumulation, and re we can therefore say that no one claims to perfection in his innovative attempts.
The benefits of the project are the purification of harmful gases and getting rid of them correctly and in a healthy manner; taking advantage of some of the gases that can be reused in industrial products and food; as well as taking advantage of the heat emitted from combustion processes (heat flue) for water desalination.
After identifying the contaminants found in the exhaust and studying the properties of each element, our aim was to then identify the best ways to eliminate polluting elements, where each element needs the most appropriate methods that can be implemented to reduce the proportion of its presence in the exhaust gases.
Quantities of air were injected at different rates in the path of the gases after they left the fire engine room to get rid or reduce the proportion of carbon monoxide and unburned hydrocarbons, different ratios were also re-used.
Your advice for those who are interested in the field
Work very hard and determine an ambition to reach, and you will. Know yourself, and work for yourself because no one will come to you or looking for you if you don’t do this. Do not stop because of any hindrances, and keep in mind that there is no invention that starts without mistakes.
