This technology pertains to the robotic system that creates multiple layers of filtration mesh in a complete structure of filtration mesh around the water inlet of a piping system. This system uses robotics and filtration mesh technology to keep multiple layers of protection, and the cleaning and maintenance of the filtration mesh, to ensure that all water entering the water inlet is water – such that all fish, debris, rocks, dirt, and other particles / sea debris that is not intended to enter the water inlet and piping system is kept outside the system.
