ESBJERG, Denmark -A team of applied industrial electronics students at Aalborg University in Denmark has built and tested a 3D-printed hybrid drone that can take off, plunge underwater, maneuver beneath the surface and then rocket back into the air, all in one seamless sequence documented in a recently shared two and a half minute video, Kaif Shaikh writes for Interesting Engineering.

28 July 2025 - Four bachelor students from AAU Energy in Esbjerg have developed a hybrid drone capable of both flying and operating underwater. The waterproof drone, designed as part of their final project, can switch between air and water modes by adjusting its propeller blade angles remotely. The drone’s dual-function capability could support tasks such as ship inspections, search and rescue missions, and defense operations.
The students - Andrei Copaci, Pawel Kowalczyk, Krzysztof Sierocki, and Mikolaj Dzwigalo - built the prototype over two semesters using 3D printing and CNC equipment at AAU.
"The team has demonstrated impressive collaboration skills, creativity, and perseverance. After countless hours in the lab, they transformed their idea into a functional prototype in just one year. It’s a remarkable achievement for an interdisciplinary student team," says Associate Professor Petar Durdevic from AAU Energy, who, along with Associate Professor Mads Valentin Bram, supervised the four students.
