Greek scientists unveil AI-powered autonomous seafloor mapping systems

Greek scientists have unveiled two autonomous systems—one aerial and one underwater—capable of creating highly detailed 3D maps of the seabed using artificial intelligence. Presented at the 90th Thessaloniki International Defense Exhibition (IDEX), these technologies are designed to support large-scale technical projects such as underwater cabling, pipeline construction, and the development of ports and marinas.

According to Dionysis Patiris, a nuclear physicist and researcher at the Hellenic Centre for Marine Research (HCMR), the underwater vehicle can also detect unexploded ordnance and identify areas vulnerable to tsunamis or underwater landslides. The systems, which were funded by the Recovery Fund, are currently transitioning to the operational stage, with training underway for programmers and operators.

The autonomous vehicles do not require a direct pilot during operation; instead, programmers set their destinations and missions, while the systems utilize built-in safety protocols to navigate difficult conditions. Following the exhibition, the aerial vehicle is scheduled to survey the southern Pagasetic Gulf to map new beach formations created by recent weather events.
