Unmanned Aerial Vehicles (UAVs), commonly known as drones, are aircraft that operate without a human pilot on board. They can be controlled remotely or fly autonomously using pre-programmed flight plans. UAVs are used in various fields, including military operations, agriculture, and surveillance, due to their ability to access hard-to-reach areas and gather data efficiently. UAVs come in different sizes and designs, ranging from small consumer drones to large military-grade models. They are equipped with various technologies, such as cameras and sensors, allowing them to perform tasks like aerial photography, mapping, and monitoring environmental changes. Their versatility makes them valuable tools in many industries.
