Framework for Combining Multiple Lightweight Underwater Vehicles into Super Underwater Vehicle

2020 IEEE/OES Autonomous Underwater Vehicles Symposium (AUV)(50043), 2020
This paper investigates the potential of using multiple, rigidly interconnected lightweight underwater vehicles (LUVs) as a cheaper alternative to using a single vehicle for mapping and monitoring. The objective is to develop a prototype super underwater vehicle (SUV) demonstrating the proficiency of the multi-vehicle approach.

Underwater Robots: From Remotely Operated Vehicles to Intervention-Autonomous Underwater Vehicles

IEEE Robotics & Automation Magazine, 2019
Remotely operated vehicles (ROVs) revolutionized the subsea industry when they were introduced in the 1960s. They were more powerful and inherently safer, and they could go deeper than divers. However, they require a tether and a support ship, which makes their use complex and expensive.

Underwater floor pattern matching with an unmanned underwater vehicle

2015 12th International Conference on Ubiquitous Robots and Ambient Intelligence (URAI), 2015
The localization of unmanned underwater vehicle (UUV) is important for the UUV to inspect or manipulator objects. We assume that there is an UUV with a camera sensor and the UUV uses the underwater floor pattern for localization. Because the pattern is known beforehand, the pattern matching between the pattern image and the camera image lets the UUV ...

On Underwater Vehicle Routing Problem

2015
In the paper we consider a problem of underwater vehicle routing (also called path planning) which can be described as follows: Given positions under water have to be inspected by the mobile robot taking under consideration water currents, minimizing the total time of the inspection.

Autonomous underwater vehicles localisation in mobile underwater networks

International Journal of Sensor Networks, 2017
Autonomous underwater vehicles AUVs form mobile underwater networks to conduct underwater surveying missions cooperatively. Due to the severe turbulence caused by water currents, individual AUV has to adjust its heading constantly to ensure reaching destination.

On controlling aircraft and underwater vehicles

IEEE International Conference on Robotics and Automation, 2004. Proceedings. ICRA '04. 2004, 2004
In this paper we make the important observation that the attitude and angular velocity control systems for gas-jet aircraft and underwater vehicles are of a special form: they are affine control systems with constant control distributions and multi-affine drifts.

An optimal indirect control of underwater vehicle

International Journal of Control, 2019
This paper considers a new problem of control related to underwater vehicles. Due to the presence of a free fluid surface and to the vortex shedding of the vehicle lifting surfaces, the mathematical model is represented by an integral-differential equation.

Control of underwater robotic vehicles

Proceedings of 1993 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS '93), 2002
Underwater robotic vehicles have been very attractive for scientific survey, construction, and maintenance in hazardous environment such as ocean and nuclear plant. The development of advanced vehicle technologies is accelerated by the demand for an underwater robotic vehicle with high performance and efficient operation in terms of time and cost. Most

From autonomous underwater vehicles (AUVs) to supervised underwater vehicles (SUVs)

Oceans '97. MTS/IEEE Conference Proceedings, 2002
The past fifteen years have seen the development of a new family of unmanned underwater vehicles without umbilical. Initially, those vehicles were operated in the direct vicinity of the mother-ship. With the increase in range and reliability, users are now willing to operate without support vessels.
