What is FPV drone and how is it different from traditional drones?
FPV (First-Person View) drone is a type of drone that allows the pilot to experience the thrill of flying as if they were on board the drone itself. Unlike traditional drones, which are typically controlled using a remote control or a smartphone app, FPV drones use a special camera and headset to provide a real-time, immersive experience.
The main difference between FPV drone and traditional drones is the way the pilot interacts with the drone. Traditional drones are typically flown using line-of-sight, where the pilot can see the drone and control it accordingly. FPV drones, on the other hand, use a camera to transmit live video feed to the pilot’s headset, allowing them to fly the drone as if they were sitting in the cockpit.
How does an FPV drone work?
An FPV drone works by transmitting live video feed from the drone’s camera to the pilot’s headset or goggles. The camera on the drone captures the surroundings in real-time and sends the video signal to a receiver on the ground. The receiver then transmits the signal to the pilot’s headset, which displays the video feed in real-time.
The pilot uses this live video feed to control the drone, relying on their vision and instincts to navigate and fly the drone. The pilot wears a headset or goggles that provide an immersive experience, making them feel as if they are flying the drone themselves.
