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.

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.

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.

Correct Operation

Guanay II is an autonomous underwater vehicle (AUV) designed to perform measurements in a water column. In this paper the aspects of the vehicle's power system are presented with particular focus on the power elements and the state of charge of the batteries. The system performs both measurement and monitoring tasks and also controls the state of charge (SoC) of the batteries. It allows simultaneous charging of all batteries from outside the vehicle and has a wireless connection/disconnection mode. Guanay II uses a NiCd battery and for this reason the current integration as a SoC methodology has been selected. Moreover, it has been validated that it is possible to obtain instant consumption from the SoC circuit. Finally, laboratory and vehicle navigation tests have been performed to validate the correct operation of the systems and the reliability of the measured data.
