Remotely Operated Underwater Vehicles (ROUVs, or just ROVs) belong to the larger group of Unmanned Underwater Vehicles (UUVs), submersible vehicles that operate underwater without the presence of a man on board, as they are remotely driven. Among the many different kinds of UUVs, ROVs are wire-guided by a human pilot which makes decisions and controls the vehicle. ROVs play an important role in a number of underwater missions for marine science, oil and gas extraction, exploration and salvage. For their various and important applications, in recent years there has been a significant increase in ROV’s demand from industry, which has stimulated increasing interest from researchers.
