As well as looking promising for 2d nanofabrication of things such as circuit boards, the system also offers precise control over depth of carving.
除了在诸如电路板之类的2d纳米制造领域似乎很有前景以外，该体系还提供了对于雕刻深度的精确控制。

Submarine depth and rolling control near the water surface is a kind of nonlinearity control problem. The change of submarine mass, speed and ocean wave make it difficult to design of control system.
The traction machine and controlsystem can be installed in any floor, the top floor height and pitch depth can be lower and smaller. It will greatly reduce the construction difficulty.
