A drone, also known as an unmanned aerial vehicle (UAV), is an aircraft that operates without a human pilot on board. Drones are typically controlled remotely by a human operator or can fly autonomously using pre-programmed instructions. They come in various shapes and sizes, ranging from small handheld models to larger aircraft with wingspans of several meters. Modern drones are equipped with a range of advanced technologies that enable them to perform a variety of tasks.
