HANGZHOU, Sept. 29 (Xinhua) — A team of Chinese researchers has achieved a breakthrough in unmanned aerial vehicle (UAV) technology, demonstrating how multi-rotor drones successfully exchanged instruments mid-flight while maintaining formation in strong wind conditions.
In a study published last week in the journal Nature, engineers at West Hui University demonstrated two quadcopters—a drone carrying a toolkit and a drone operator equipped with an extendable robotic arm—that successfully performed successive multiple docking maneuvers with an average error of 8 millimeters.
When one drone hovers directly above another, its propellers create a powerful downdraft that destabilizes the UAV below. Tests have shown that with a vertical distance of just 0.6 meters, the downdraft from the operating "thrusters" reaches over 13 m/s, equivalent to a "strong wind" of force 6 on the Beaufort scale.
Researchers claim that this joint flight, carried out using the FlyingToolbox operating system, is the first of its kind in the world and has solved the technical challenge of synchronous close-range flight and high-precision operations.
A team of scientists from Xihu University has developed a soft electromagnetic docking module, an intelligent electromagnetic interface that automatically attaches upon contact, significantly improving docking accuracy.
In the published videos, the system also performed even more complex tasks: coordinating the work of three drones and mid-air capture by two drones in motion.
In the near future, advanced aerial robotic systems may help humans perform complex and dangerous tasks in higher and more distant places, according to developments. -0-
