They are equipped with sensors, cameras and manipulators.

Write short notes on Fixed-Wing Drone.

Answer

A fixed-wing drone has rigid wings, similar to an airplane, which provide lift without the need for vertical rotors. It requires energy only to move forward, making it highly energy-efficient. These drones can cover long distances, map large areas and loiter for extended periods with flight times averaging a few hours. However, fuel-powered fixed-wing UAVs can stay aloft for 16 hours or more. They are capable of flying at high altitudes, carrying heavier payloads and are more stable in flight, making them ideal for long-duration missions and extensive aerial monitoring.
