Design Optimisation of a Search and Rescue Micro-Submarine

A micro-submarine (micro-sub) is a very small unmanned submarine, which is normally being deployed for various dangerous underwater tasks effectively with minimum cost and risks. The micro-sub design must be optimised in every aspect of its practicability and operation ability. A combination of indu...
