In this article, a cruising autonomous underwater vehicle (AUV) r2D4 and examples of its achievements to date are introduced. With the objective of realizing an intelligent multirole platform for deep-sea surveys, the r2D4 development program was started in 2001. Launched in 2003, the r2D4 had achieved several practical missions by the time of its last dive in 2010. Enhanced vehicle autonomy was realized by applying new technologies in navigation, control, positioning, and sensing, which enabled the capabilities of tackling more challenging undersea missions. The r2D4 is a multirole platform that is easily able to be modified to meet the applications of diverse purposes. Since its first dive in September 2003, the r2D4 has successfully completed a total of 67 dives in bodies of water worldwide.

The Autonomous Underwater Vehicle (AUV) „ABYSS“ is a modular AUV designed to survey the ocean combining geophysical studies of the seafloor with oceanographic investigations of the overlying water column. The basic mission of ABYSS is deep-sea exploration, specifically in volcanically and tectonically active parts, such as mid-ocean ridges. With a maximum mission depth of 6000 meters, the AUV uses several technologies to map the seafloor accurately and determine its geological structure with applications from geology to biology to mineral exploration.

History Of

In 2020, the autonomous underwater vehicle (AUV) has already become a vital part of deep-sea research. There is a long history of R&D of AUVs that dive into the deep sea, where radio waves cannot reach, thus making remote control difficult so that no help can be provided, which implies that careful and adequate preparation is necessary. Their successful development has been based on the accumulation of experience and achievements contributing to the remarkable results that no other system can produce. The aggressive R&D of Japanese AUVs started approximately 40 years ago. This paper looks back at this history and introduces various Japanese AUVs.

When cruising underwater, the Autonomous Underwater Vehicle (AUV) oscillation will affect some sensors’ measuring precision. In this paper, the method of equivalent entities is used to build the AUV’s solid model, and the AUV’s fluid-solid coupling system together with its wet modal is analyzed using ANASYS software. In addition, the AUV’s bending mode and breathing mode under different depths are discussed, which will reflect the changing trends of AUV vibration frequencies during operation. The conclusion can provide the theoretical basis for the AUV structure design when certain measuring task is performed using sensors.
