The I Build Stuff team, led by engineer John Tse, has introduced an innovative autonomous umbrella that can follow its owner. This unique drone, equipped with propellers and depth sensors, allows users to free their hands while providing comfort in any weather, according to the press.
The use of a ToF camera instead of conventional optics has been a key factor in ensuring the drone's stability. Unlike traditional cameras that can lose track of an object due to visual interference, the ToF sensor operates on the principle of light reflection, allowing it to accurately determine the distance to the owner even in poor visibility conditions.
The umbrella, as a familiar item, has remained unchanged for a long time and has always occupied one hand of a person, creating inconvenience. John Tse decided to change this outdated concept by creating a high-tech quadcopter.
The umbrella's structure is made from durable and lightweight carbon fiber and nylon, which was printed using a 3D printer. Four powerful propellers are hidden under the canopy fabric, making the device compact and stable in flight.

One of the main challenges was to properly distribute the load, as the central rod is the only rigid part of the structure. The engineer developed an innovative mounting system with loops and elastic elements, allowing the drone to remain securely in the air even in gusty winds while maintaining the classic appearance of an umbrella. Work on the prototype took almost a year, during which the author faced various challenges, but ultimately achieved the desired results.

This model is significantly different from previous ones, as the umbrella is now fully autonomous. A complex navigation system was implemented, utilizing a ToF camera that scans the environment using light pulses instead of standard cameras or GPS.

This technology enables the creation of a three-dimensional map of the terrain and accurately tracks the user's head position, even in low visibility conditions. Data processing is carried out using a Raspberry Pi microcomputer, which manages the flights.
“The goal of the project was not only to create a drone but to make it capable of automatically following a person,” shared the creator. Now the umbrella moves in line with the owner, keeping the canopy centered. Despite its high complexity, the device functions even in heavy rain, turning a futuristic concept into a practical tool for urban environments.
During the project, the engineer created a short film, which he posted on YouTube. This film showcases the main stages of the work, which took almost a whole year.
