Quadcopters are primarily a form of VTOL (vertical take-off and landing vehicle) rotorcraft that has four rotors or propellers that enable propulsion. The first attempt to create quadcopters was documented in 1907 by Jacques and Louis Berget. They created a prototype and tested the quadcopters; however, their early designs were unstable and flying seemed impractical. Étienne Boehmite, a French engineer, managed to create a stable quadcopter in 1924 Figure 1 capable of flying approximately 360 m (1,181 ft), creating a world record. The US Army also created quadcopters and conducted flight tests, but the program was later abandoned. Early quadcopter designs had only one main rotor connected to the tail rotor so that overall counterbalance could be achieved. The prototype using a single main rotor was of no use and added complexity to the process. The single rotor used about 15% of the energy while no thrust was created to allow the quadcopters to lift. The other problem was the large rotor blades, which were heavy and about 5 meters long, which made the quadcopters inefficient. Most quadcopters have the motor mounted in the fuselage while four rotors are driven via shafts or belts. The main challenge of quadcopters is maintaining stability while managing to maintain the same speed on all rotors. Say no to plagiarism.

Bothezat designed a Convertawings Model A quadcopter in the year 1956 and was the first model to use propulsion to enable forward thrust; this meant that operators were able to control the aircraft's yaw, pitch and roll. The quadcopter has undergone significant changes over time, as companies like Blade, DJ, Parrot, and others have added new technologies like flight controls and the ability to take aerial photography. The quadcopter further added features such as a coaxial helicopter and agility against wind resistance, while it also used three-axis gyroscopic technologies to improve the level of stability. ESCs (Electronic Speed ​​Controllers) are enabled to control flight with a remote control transmitter. There are various types of aerodynamics used by the quadcopter so that it can be driven through its four rotors. The quadcopter relies on its center of gravity to manage its balance and is based on a simple design concept. The use of quadcopters has increased significantly in recent years and they are widely used in the field of research and robotics and in research in difficult and dangerous places; used by military and community agencies for various tasks (Quadcopters Arena, 2017). The 20th century saw the rise of quadcopters and now they are widely used as an innovative technology-based product for surveillance, GPS-enabled tracking, various research works in dangerous places such as active volcanoes and to monitor flood situations and other natural disasters. Quadcopter technology gradually became economical and due to their ease of use they became very popular with the public for entertainment, photography and for supervising public works. The way forward centers on the use of quadcopters to replace police patrolling the streets; Amazon also plans to use them for goods delivery, and the construction industry uses them for general work monitoring and supervision.
