Our team has finalized the electronic integration architecture for our autonomous marine robots, a key milestone in ensuring reliability under real-world conditions. The selected solution is built around a high-performance sealed enclosure combined with secondary circuit protection, delivering both maximum robustness at sea and ease of maintenance. This approach, validated through a strict industrial testing protocol, is designed to be directly industrializable and to support the continuous evolution of our systems. Recent achievements : - The engineering team defined and validated the waterproofing architecture for our marine robots, adopting a “Dry Pod” approach: all electronic components are enclosed within a certified IP68 hermetic casing (fully resistant to immersion). - A dual-protection strategy has been implemented: the sealed enclosure acts as the primary barrier, complemented by a protective conformal coating on the printed circuit boards, ensuring that a micro-leak does not immediately result in system failure. - The architecture integrates active condensation management (a natural phenomenon caused by temperature variations in marine environments) through specialized breathable membranes and internal humidity sensors. - All materials in contact with the marine environment were selected for corrosion resistance: tinned copper wiring, marine-grade stainless steel fasteners, and sea-certified connectors. - A rigorous testing protocol has been established, including vacuum testing, 30-minute immersion tests, thermal cycling, and bubble leak tests, ensuring reliability before any field deployment. - The design prioritizes maintainability and scalability: unlike electronics encapsulated in resin (which are non-repairable), our architecture allows for servicing, updates, and module replacement. - The battery is housed in a separate sealed compartment, reducing risk and simplifying field maintenance operations.
