A quadcopter is a type of drone that is powered by four rotors. These rotors are arranged in a cross formation, allowing the quadcopter to lift off, hover, and maneuver in various directions. Quadcopters are commonly used for aerial photography, recreational flying, and even in agriculture for crop monitoring. The design of quadcopters makes them stable and easy to control, which is why they are popular among hobbyists and professionals alike. Many quadcopters are equipped with cameras, GPS, and other technology, enhancing their capabilities for tasks such as mapping and surveillance.
