A team of engineering students from Aalborg University in Denmark has developed a groundbreaking hybrid drone capable of operating both in the air and underwater.
Built entirely using 3D printing technology, the drone has drawn international attention for its ability to seamlessly transition between flying and swimming.
The fully 3D-printed prototype uses variable-pitch propellers that adjust blade angles depending on the environment.
In the air, the propellers tilt to generate lift; underwater, they flatten to provide efficient thrust. This single propulsion system eliminates the need for complex mechanical components typically found in dual-mode drones.
The drone can autonomously dive, navigate underwater, resurface, and resume flight, all in one continuous motion.
Video demonstrations released by the students have gone viral, showcasing the drone’s smooth, reliable performance in both environments.
In contrast to other hybrid drones such as the Mirs-X, which relies on motorized gimbal-mounted propellers to shift between air and water, the Aalborg University design emphasizes simplicity and cost-efficiency.
By using 3D-printed parts and a streamlined control system, the students have produced a versatile platform suited for real-world applications.
Potential uses for this amphibious drone include search-and-rescue missions, environmental monitoring, marine infrastructure inspections, and military reconnaissance.
Its dual-environment capabilities allow it to survey disaster zones, inspect submerged equipment, or collect underwater data, all while retaining the ability to fly away when the task is complete.
This student-led project demonstrates the power of innovation, low-cost manufacturing, and software integration in shaping the future of unmanned systems.
With continued development, the drone could set new standards for how aerial and aquatic robotics are deployed in both civilian and defense sectors.
