Drones, also known as unmanned aerial vehicles (UAVs), are remote-controlled or autonomous flying devices. They are equipped with cameras, sensors, and communication systems, making them useful for a variety of applications such as aerial photography, surveying, mapping, delivery services, and recreational use. Advances in drone technology have improved flight stability, battery life, and range, enabling more complex and longer-duration missions. Drones are widely used in industries such as agriculture, construction, and emergency response.
