It utilizes onboard flight control systems, sensors, communication modules, and other equipment to achieve autonomous navigation, target recognition, and data collection.

[0003] Multi-rotor UAVs mainly rely on the continuous rotation of propellers to provide lift and power. During operation, the motors and propellers consume a lot of electricity, and the flight time is generally short, which makes it difficult to meet the needs of long-distance and long-term operations, limiting their application scope. At high altitudes, the power output needs to be continuously increased to maintain flight stability, which increases energy consumption. Therefore, a bionic energy-saving UAV is proposed.
