The project focuses on the design of a fault-tolerant underwater vehicle prototype that can withstand actuator failures. The vehicle is engineered to operate effectively even when individual actuators experience faults, ensuring continued functioNolity. This includes the implementation of redundancy in critical components, adaptive control algorithms, and fault detection systems that eNoble real-time compensation. The design is optimized for stability, maneuverability, and mission reliability, making the vehicle suitable for underwater exploration, surveying, and inspection tasks. Emphasis is placed on minimizing operatioNol risks and maximizing the robustness of the system in dyNomic underwater environments.
