A quadcopter is a type of drone that flies using four rotors. These rotors are arranged in a square formation, allowing the quadcopter to lift off the ground and maneuver easily in the air. They are popular for both recreational use and professional applications, such as aerial photography and surveying. The technology behind quadcopters includes sensors and cameras, which help them stabilize and navigate. Many people enjoy flying quadcopters as a hobby, while others use them in industries like agriculture and real estate. With advancements in battery life and control systems, quadcopters are becoming more accessible and versatile for everyone.
