Autonomous Umbrella Drone Follows Users With 3D Tracking

- John Tse of YouTube channel I Build Stuff created an autonomous flying umbrella that hovers above users and trails them hands-free, shielding them from rain and sunlight — upgrading a remote-controlled prototype he previously built.
- The device uses four propellers mounted on folding arms that collapse inward when carried and lock rigidly into place during flight, with hinges, rubber bands, and custom plates reducing shake.
- A time-of-flight depth camera tracks the user in 3D — even in low light — while a Raspberry Pi pinpoints the person's head and tells the flight controller which direction to move so the umbrella stays centered overhead.
- A professional flight controller and embedded GPS keep the device balanced and holding position outdoors; most structural parts were 3D-printed in carbon-fiber nylon for strength and precision.
- The build took nearly a year, with broken parts, software failures, and disconnected components forcing repeated redesigns before the final prototype flew reliably.
- The finished device can hover, follow a person, and operate in heavy rain, though Tse acknowledges it is functional rather than refined.
Why it matters: The project lays out a reproducible blueprint for personal-following drones — folding-arm quadcopter propulsion, 3D depth-camera person-tracking, and 3D-printed carbon-fiber frames — using off-the-shelf hardware like a Raspberry Pi. The reported near-year failure cycle illustrates how far hobbyist single-unit prototypes still sit from mass-produced consumer gear.
