So the natural progression is to combine a love of water with the technical electrical engineering skills I have been learning. Now, the design and construction of submarine technology is quite different than a standard ship. While watertight integrity is needed on a surface ship, the design of a submarine must also accommodate a sealed access hatch to vital components. Also, for model ships, control becomes an additional problem due to both visual and radio ranges. As the water contains more particulate matter, range decreases.
Visual range is probably the greatest limiting factor.
As with model radio control airplanes, once the model tests your visual range, it becomes increasingly difficult to determine orientation and proper maneuvering commands. Depending on the murkiness of the water, visual range could vary from 5 cm to 50 m. On average, in a small lake or pond, a well-painted submarine can be seen in up to 1.5 m of depth. These factors need to be kept in mind while designing a robotic submarine. Effectively, what good is it to design a machine with exceptional performance when a few critical human factors limit performance.
