FATCAR-AUV: Fault Tolerant Control Architecture of AUV

2007 International Bhurban Conference on Applied Sciences & Technology, 2007
Due to versatility, compact size, independence and covertness, autonomous underwater vehicles are a highly valuable asset in the underwater battle space. Possible missions for autonomous underwater vehicles (AUVs) range from dedicated and organic mine counter measure (MCM), rapid environmental assessment, and special operations to reconnaissance ...

Momonga-like AUV –AUV with a variable wing–

2018 IEEE/OES Autonomous Underwater Vehicle Workshop (AUV), 2018
Water column sampling is one of the important ways to acquire the information used for detecting global warming, water pollution, climate change, and so on. Recently, water sampling is conducted by robots called Autonomous Underwater Vehicles (AUVs) those works automatically without tether expecting the efficient and the wide range sampling.

AUV Parameter Identification

IFAC proceedings volumes, 2009
Abstract An extended Kalman filter is used to tackle the problem of parameter identification of an autonomous underwater vehicle (AUV). Since a large number of parameters must be identified, two alternative sub-approaches are investigated. A classical approach seems to have a better performance in cases where a specific parameter will be identified ...

Balloon AUV: Seawater Sampling AUV Using Active Buoyancy Control

2018 IEEE/OES Autonomous Underwater Vehicle Workshop (AUV), 2018
A significant amount of waste has been thrown into the ocean, and the debris from the waste has been sunken into the deep sea. So we proposed an autonomous underwater vehicle to collect water-quality data in deep water and sample water in the area which pollution level is high.

Dynamics of an Autonomous Underwater Vehicle (AUV) towing another AUV

2023
This thesis studies the motion of an autonomous underwater vehicle towing another autonomous underwater vehicle which is a large as it is. The towed vehicle cannot be assumed to be just a mass attached to the towing vehicle. There is an interaction between the two vehicle.

ROVs and AUVs

2017
The most significant breakthroughs in science are often made as a result of technological developments and innovation. A new capacity to gather more data, measure more precisely or make entirely new observations generally leads to new insights and fundamental understanding. The future of ocean research and exploration therefore lies in robotics: marine

The Hybrid Glider/AUV Folaga

IEEE Robotics & Automation Magazine, 2010
The paper describes the current evolution of the class of Fo?laga underwater vehicles, whose actuation mechanism is a hybrid between oceanographic gliders and standard, self-propelled autonomous underwater vehicles (AUVs). The Fo?laga vehicles have been designed for coastal oceanography and environmental sampling; the application-oriented design ...

Morpheus AUV Development

2001
Abstract : The long-term goal of this project is to develop an effective field-reconfigurable non-metallic AUV platform for use in littoral ocean sampling and to benefit broader Navy goals related to improved Mine Counter Measures. Accomplishing this goal requires additional effort in the hardening and refinement of the existing Morpheus AUV for fleet ...

Multi-AUV SOM Task Allocation Considering Initial Orientation of AUV

2018 IEEE 8th International Conference on Underwater System Technology: Theory and Applications (USYS), 2018
Considering that the Autonomous Underwater Vehicles (AUVs) have different initial azimuths in two-dimensional plane, an improved self-organizing map model is put forward. Each AUV in the model is accessed. The AUV, which has the shortest path under kinematic constraints and different azimuths, is selected for task assignment.

Obstacle Avoiding Policy of Multi-AUV Formation Based on Virtual AUV

2009 Sixth International Conference on Fuzzy Systems and Knowledge Discovery, 2009
Based on the local path planning for Autonomous Underwater Vehicle (AUV) with uniform motion, a fuzzy logic control algorithm is adopted for AUV with variable velocity. And based on the formation control method and the geometrical kinematic relation of the formation order, the multi-AUV formation of obstacle avoiding can be translated into the path ...
