I. Introduction
Unmanned aerial vehicles (UAVs) that can travel great distances and tiny drones made for limited places are both included in the category of drones, which includes a broad range of flying robots. [1] These airborne vehicles are capable of carrying harmful or nonlethal payloads and are operated without the need of human pilots, relying instead on remote or autonomous navigation. It's critical to differentiate between drones and other types of airborne weapons that don't fit into the drone category, such as ballistic missiles, cruise missiles, artillery projectiles, torpedoes, mines, and satellites. A wide variety of drones are now conceivable because to recent improvements in manufacturing methods, navigation systems, remote control skills, and energy storage systems. These drones are suited for situations where human presence may be difficult, risky, or impossible. [2] Flying robots have become more common in military reconnaissance, planetary exploration, and search-and-rescue missions throughout time. Drones are outfitted with a variety of sizes and payloads, depending on the intended purpose. Drones have several benefits, which has led to a lot of research being done to improve and optimise their performance. Numerous jobs, including reconnaissance, surveillance, patrolling, freight transfer, and atmospheric research, might be accomplished by drones.
