Autonomous navigation of underwater vehicles

IEEE Oceanic Engineering Society. OCEANS'98. Conference Proceedings (Cat. No.98CH36259), 2002
The goal of the work is to propose a method to solve with visual means the problem of underwater navigation of an autonomous vehicle moving in deep sea in order to perform inspection of a pipe positioned near the ocean floor. We refer to the ability of an autonomous system to determine its motion with respect to the environment. It is well known that a

Development of autonomous underwater vehicles in Japan

Advanced Robotics, 2002
In the hope of expanding underwater observation and research, the Institute of Industrial Science (IIS) at the University of Tokyo started extensive R&D on autonomous underwater vehicle (AUV) in 1984. IIS has constructed nine vehicles, including three ocean-going vehicles, one lake survey vehicle and various testbed vehicles.

A formation flying algorithm for autonomous underwater vehicles

IEEE Conference on Decision and Control and European Control Conference, 2011
A control algorithm for the problem of formation flying for autonomous underwater vehicles is presented. Using a restrictive communication scheme and LQ optimal control, the control algorithm respects the limitations of underwater communication and on-board computing power.

Path Planning for the Autonomous Underwater Vehicle

2013
This paper introduces a novel method to find the optimal path for Autonomous Underwater Vehicles (AUVs). AUVs have gained importance over the last few years as service and research tools in a variety of applications. Path planning is one of the challenging tasks when dynamic obstacles are encountered.

Navigation of underwater autonomous vehicles

Proceedings of the 2000 International Symposium on Underwater Technology (Cat. No.00EX418), 2002
The paper suggests an approach to solving the problem of navigation of an underwater vehicle using acoustic and geometric data and gravitation field potential changing in time. The known methods of making seafloor acoustic maps are not effective for correction of coordinates in areas of smooth relief and in shallow water. The suggested algorithm allows

The Phoenix Autonomous Underwater Vehicle

2013
The Phoenix autonomous underwater vehicle (AUV) is a robot for student research in shallow-water sensing and control (Figure 1). Phoenix is neutrally buoyant at 387 pounds (176 kg) with a hull length of 7.2 feet (2.2 m). Multiple propellers, thrusters, plane surfaces and sonars make this robot highly controllable.

Autonomous underwater vehicles

2018
usc Refereed/Peer-reviewed The chapter deals with the development of indirect adaptive controllers based on Fuzzy Control approach for Autonomous Underwater Vehicles (AUVs). The non-linear, coupled and time-varying dynamics of AUVs necessitates the development of adaptive controllers.

GPS in autonomous underwater vehicles

6th International Conference on Electronic Engineering in Oceanography, 1994
The UK Natural Environment Research Council (NERC) is developing an autonomous underwater vehicle (AUV) capable of measuring, storing and transmitting full-depth oceanographic data over basin-wide tracks. An important feature of this AUV (known as Autosub) is that it will surface periodically for short periods in order to communicate with its base and ...

Research and Applications of Autonomous Underwater Vehicles.

Science and Technology of Engineering, Chemistry and Environmental Protection
Autonomous Underwater Vehicle (AUV) technology has been developed in the field of underwater surveying over the past decades. Today as climate change and the energy crisis becoming increasingly urgent matters. Simultaneously, as technology is moving towards data-driven digitization, AUV technology is expanding into several other fields.
