What are drones, and how do they work?
Drones, also known as unmanned aerial vehicles (UAVs), are remote-controlled or autonomous flying devices that use rotors or propellers to generate lift and propulsion. They typically consist of a lightweight frame, motors, propellers, sensors, and a control system. Drones can be controlled manually using a remote controller or autonomously through pre-programmed GPS coordinates and sensors.
The control system of a drone typically includes a flight controller, which receives commands from the remote controller or GPS system and interprets them to control the motors and propellers. This allows the drone to take off, land, hover, and move in any direction. Additionally, drones often come equipped with sensors such as GPS, accelerometers, and gyroscopes, which provide data on the drone’s position, orientation, and movement. This data is used to stabilize the drone and ensure smooth flight.
