Drones, officially known as Unmanned Aerial Vehicles (UAVs), are aircraft that operate without a human pilot aboard. These devices can be remotely controlled or can fly autonomously through software-controlled flight plans in their embedded systems working in conjunction with GPS.
There are various types of drones, ranging from small consumer drones used for recreation and aerial photography to larger drones utilized for military and commercial purposes. Some drones are equipped with cameras, sensors, or even packages for delivery services.
Drones have multiple rotors, typically four or more, that enable vertical takeoff and landing (VTOL) capabilities. They are powered by electric motors and use digital controllers to maintain stability and control the flight. Drones receive commands through radio signals or wireless networks to execute tasks.
The uses of drones are diverse and widespread. They are employed in industries such as agriculture, construction, filmmaking, surveillance, search and rescue operations, and even in scientific research. Drones have revolutionized various sectors by offering cost-effective and efficient solutions.
Due to safety and privacy concerns, many countries have established regulations for operating drones. These rules often involve restrictions on flying near airports, over populated areas, and above a certain altitude. Pilots may need certification depending on the drone's weight and purpose.
