Drone is an aircraft that operates without a human pilot on board. Drones can be remotely controlled by a human operator or autonomously programmed to follow a specific flight path or perform certain tasks. Key components include a frame, motors, propellers, a flight controller, and a rechargeable battery. Drones are controlled through a remote controller or a mobile device with a dedicated app. Advanced drones may have GPS and other navigation systems to enable autonomous flight and precise positioning.
