Drones, also known as unmanned aerial vehicles, are aircraft that operate without a human pilot onboard. They exist to perform aerial tasks that are difficult, time-consuming, or risky for manned aircraft. Early drones were developed mainly for military observation, but advancements in electronics, sensors, and navigation systems have expanded their use into many civilian and commercial fields.
Modern drones combine lightweight materials, compact motors, flight controllers, and communication systems. These components work together to enable stable flight, precise navigation, and aerial data collection.
Drone technology extends human capability by allowing remote access to areas that are difficult or unsafe to reach. It supports monitoring, mapping, and data gathering across various environments.
