Observer-based controller Design for Remotely Operated Vehicle ROV
Proceedings of the 11th International Conference on Informatics in Control, Automation and Robotics, 2014This paper presents a method to design an observer-based controller that simultaneously solves global estimation of state and asymptotic stabilization of an underactuated remotely operated vehicle moving in the in three-dimensional. The vehicle does not have a sway and roll actuator and has only position and orientation measurements available.

Remote Operating Vehicle (ROV)
1998United States government and individual states mandate reporting on cultural resources in areas which are subject to development. The requirement that an archaeological survey is necessary to obtain permits for construction in the maritime environment has produced a huge number of reports.

Object detection/tracking toward underwater photographs by remotely operated vehicles (ROVs)
Future Generation Computer Systems, 2022Abstract Owing to the shortcoming of image blur, scale diversity, and complex backgrounds, underwater target detection and tracking is a tough challenge in real-world ROVs applications. In this paper, an underwater target detection method based on the class-weighted YOLO network is proposed.

Identification of Remotely Operated Vehicle and Benchmark ROV Model
2020The material discussed here on methods of determining the hydrodynamic parameters is only a small fraction of the enormous amount of works done and literature available. It is a short summary and includes the work done by the authors, literature published, and some of the papers referenced during the works. The primary goal is to estimate the model and

Failure Analysis of Fasteners in a Remotely Operated Vehicle (ROV) System
Journal of Failure Analysis and Prevention, 2015A failure analysis study was carried out on AISI 204 Cu stainless steel full-threaded fasteners and end-threaded SS 316L fasteners used in a deep water work class ROV system. The AISI 204 Cu stainless steel full-threaded fasteners were used in a Ti–6Al–4V alloy pressure case.
