Introduction
This drone possesses exceptional capabilities for transitioning from flight to underwater operation.
According to foreign media NoteBookCheck, four undergraduate students from Aalborg University in Denmark have developed a drone that can dive underwater and instantly switch to flying mode.
This project is part of the students’ undergraduate thesis,and they completed the drone prototype design in two semesters, manufacturing and full-process testing, with the core technology being a variable pitch propeller system, characterized as follows:
-
The blades can rotate around their own axis to change the pitch.
-
When “swimming” underwater, the blade angle is adjusted to a low pitch.
-
When switching to flying mode, it adjusts to a high pitch.
According to their published video, this drone features a circular ergonomic body design, with a shell made from 3D printing, housing the battery and control unit, and equipped with four symmetrically distributed dual-blade rotors, utilizing an extendable design.
In practical use, this drone first takes off from the ground, flies around a building, then dives into a swimming pool, moving forward, capable of underwater navigation, and repeatedly switching between flying on land, all without any stuttering or failures.
NoteBookCheck commented that their project is somewhat similar to the amphibious drone developed by a team at Rutgers University in the USA in 2015, but at that time, the American drone could only be controlled via a wire, whereas the Danish students’ project achieved wireless control and mounted a sports camera.
