autonomous flying umbrella follows and shields users from rain and sunlight
"An updated version of the umbrellaremote-controlled one, the hands-free device hovers above the user and trails them wherever they go, keeping them dry and cool without needing to hold anything. The autonomous flying umbrella is a drone disguised as an everyday object. Its design keeps the familiar shape of a normal umbrella but hides flying technology just under the yellow surface. Four propellers are mounted around the material using a custom internal frame, and they provide the lift and control, just like a quadcopter drone."
"It's because the umbrella's center rod is the only strong part, but mounting everything directly there would make it bulky and hard to carry. The solution was folding arms, where each propeller sits on an arm that folds inward when not in use and locks firmly into place when opened. This allows the flying umbrella to stay compact when carried and stable when flying."
An autonomous umbrella-shaped drone hovers above and follows a person to shield them from rain and sunlight without requiring hands. The design retains a familiar umbrella silhouette while concealing four propellers and a custom internal frame beneath the canopy. Folding arms allow each propeller to tuck inward for compact carrying and lock firmly open for flight, balancing portability and stability. The locking system combines hinges, rubber bands, and precision plates to minimize vibration and maintain structural tightness during flight. Development included a smaller test drone to trial systems safely, and tracking evolved to a time-of-flight depth camera that creates depth images to locate a person's position.
