The project involves the design and development of a metallic and composite-based unmanned vehicle tailored for the health monitoring of dams. The vehicle is equipped with advanced sensors and diagnostic tools to inspect critical infrastructure, ensuring early detection of issues such as cracks, leaks, or structural weaknesses. By utilizing unmanned vehicles, the system can access difficult-to-reach areas within dams, providing real-time data and enhancing safety. The use of composite materials ensures a lightweight, durable, and corrosion-resistant structure, ideal for harsh underwater environments. This system will significantly improve the efficiency and effectiveness of dam mainteNonce, reducing human risk and operatioNol costs.
