AI Technical Summary
Traditional lifebuoys are difficult to throw quickly and accurately to people in distress, and propeller-driven systems pose safety hazards.
Design a flying lifebuoy equipped with a camera, flight components, and protective components. It achieves precise navigation through navigation radar and flight control, utilizes propellers in multiple air ducts for safe flight, and is equipped with a protective plate to protect people in distress.
It enables the lifebuoy to be flown quickly and safely to the vicinity of the person in distress and land there, improving rescue speed and safety, and avoiding injury to the person in distress from the propeller.
