3D-printed, thrust vectoring Unmanned Surface Vessel (USV)

Development period: June 2023 - May 2025
Patent number: 1010721
Date received: 21.06.2024
Institution:
Hellenic Industrial Property Organization (OBI)

The developed USVs (Unmanned Surface Vessels) are electric powered, 3D-printed robotic boats, that utilize thrust-vectoring air propulsion. They can autonomously navigate by GPS and magnetometer, according to the instructions given by the installed controller, which is based on open navigation-based controller software (Ardurover 4.5). Furthermore, they can be remotely controlled with 2.4GHz multichannel radio system, based on the OpenTX protocol.
They are intended for use in calm waters such as small lakes, ponds and reservoirs, especially in waters with dense vegetation, for inspecting water platforms, floaters, and other water structures, as well as for water quality monitoring. Moreover, they can be used as safety drones, for accompanying swimmers and water athletes. It is possible to utilize these USVs in search and rescue missions as well, providing extra coverage due to the extended operation time compared to standard UAVs (Unmanned Aerial Vehicles). Therefore, they carry a payload of live-stream camera, HD recording camera and telemetry system. Despite the fact that they are intended mainly for calm waters, they are capable to withstand light winds due to their design and low CoG, allowing operation at sea, in conditions similar to the ones found at harbors and marinas.
Finally, the modular design enables the build of identical hulls under a variety of sizes. At the moment four variations of the prototype have been built.
