The drone is an aircraft that is controlled by a human pilot who is not on board, but which operates "remotely" thanks to the commands transmitted, usually by a kind of remote control, even if usually there are no precise definitions of a drone.

The flight mechanism is quite simple: drones are equipped with rotors that push and lift them into the air. Remote-controlled ones can use Wi-Fi, cellular data, radio signals or other types of frequencies that allow you to control them using a special controller or an app in your mobile phone. And the camera built into almost all drones allows you to follow its trajectory.

Thanks to virtual reality headsets, it is even possible to experience the flight yourself! Let's not go into too much detail about how it works, but let's see better what they are used for: people who buy drones use these technologies for recreational and personal purposes, above all to record artistic videos and to see places in 360 degrees.

However, companies use drones to transport objects (such as the transport of Amazon parcels) but they are also used by the police and public bodies to conduct investigations and for security reasons, for example during the pandemic they were used to check that the safety measures regarding the lockdown were respected. In other countries, however, such as France, they are used to disinfect city streets, while the firefighters use these devices for operations to find missing persons.

Automatic drones work like the machines we have talked about previously and like the latter, they can be both fully and partially automatic, therefore needing supervision by humans or their control in case of problems.
