Oceans cover 70% of our earth’s environment, as well as hold clues to the mysteries of human’s past. There are large amount of underwater minerals, oil and gas; therefore, Oceans are vital for the future survival of mankind. Marine scientific research and technology development is currently undergoing all over the world, but the secrets of our oceans have remained largely undiscovered. There is still a long way to go to understand the Earth’s Oceans and putthem in a human scale. Until now, large numbers of facilities including research vessels, satellites, buoys, and various kinds of underwater submersibles have been used for marine explorations. Specially, underwater submersible technologies have made substantial strides over the past two decades. From manned submersibles to unmanned submersibles, the development of such systems has been unprecedented. Starting from nascent navigation and control algorithm research in laboratories, applied underwater technology has developed considerably and at present manned submersibles are able to dive thousands of meters to take scientists directly to the depths of the Oceans to conduct underwater observations and sampling operations, underwater gliders have recently crossed the Atlantic Ocean and surface unmanned platforms the crossed the Pacific. Underwater submersibles have obviously provided an extension of the human senses and reach towards exploration and exploitation of the Oceans. We are indeed at the dawn of a new era when exciting developments in underwater submersible technology will provide humans with advanced tools to explore and exploit the Oceans at an unprecedented scale and in a sustainable manner. There are various developing technologies with respect to underwater submersibles, including modeling, sensor integration, mission and motion planning, guidance and control, position and localization, underwater manipulation, fault detection/tolerance, and multiple underwater submersible systems, and other. Advances in these technologies have considerably pushed the state of applications for underwater submersibles. With increasing attention paid to the research and development of underwater submersibles, as well as the continuous new application demands for these platforms, the underwater submersible technologies face an unprecedented development opportunity. Meanwhile, the unique nature of the underwater working environment and its typically harsh conditions has unavoidably led to some technological bottlenecks. It is valuable and meaningful to evaluate advances and challenges of the underwater submersible technologies in retrospect, in order to improve future technologies.
