Seaber
French maker of YUCO and MARVEL micro-AUVs that dive to 300m for hydrography, aquaculture research, and defense missions.
SEABER is a French marine robotics company headquartered at 29 Cours de Chazelles in Lorient, a naval and maritime technology hub in Brittany, France. The company designs and manufactures micro autonomous underwater vehicles (micro-AUVs) for oceanographic, commercial, and defense applications. Its flagship product line, the YUCO AUV, is a compact underwater drone weighing approximately 10 kg and measuring around 1 meter in length, capable of diving to depths of 300 meters with 8 to 10 hours of autonomous operating endurance. YUCO is offered in eight sensor-payload configurations tailored to different missions: Carrier (modular payload bay), Scan (side-scan sonar), CTD (conductivity-temperature-depth oceanographic sensing), Physico (physico-chemical water sampling), PAM (passive acoustic monitoring for marine mammal detection), 3DSS (3D scanning sonar), Lumen (optical/camera imaging), and eDNA (environmental DNA water sampling for biodiversity assessment). For larger-scale and defense-oriented missions, SEABER produces the MARVEL AUV, a bigger vehicle available in five variants — Scan, Magneto (magnetometer for object/mine detection), MBES (multibeam echosounder for bathymetric mapping), 3DSS, and Lumen — targeted at security and military survey operations. The company complements its hardware with SEAPLAN, proprietary mission-planning software used to program and manage AUV survey routes. SEABER's vehicles are applied across a range of use cases, including coastal and harbor monitoring, hydrographic and bathymetric surveying, marine biology and aquaculture research, search-and-rescue support, mine countermeasures, and anti-submarine warfare training exercises for naval forces. The company's small, lightweight AUV form factor is designed to allow deployment from small boats or by a single operator without the need for large support vessels or cranes typically required by bigger AUV systems, differentiating it from larger oceanographic AUV makers that build vehicle classes intended for deep-ocean, long-endurance survey work. In July 2026, SEABER participated in the Smart Sound Connect marine robotics demonstration event, showcasing its underwater vehicle technology alongside other maritime robotics developers. SEABER maintains direct customer support through a dedicated client login portal on its website and lists [email protected] as its official contact channel. The company's focus on compact, rapidly deployable micro-AUVs positions it within a niche of the unmanned marine vehicle market oriented toward coastal, harbor, and near-shore survey and security missions rather than blue-water long-range oceanographic exploration.
