Subsea vehicles are specialized machines designed to operate underwater. They are used for various purposes, including exploration, research, and maintenance of underwater structures. These vehicles can be remotely operated or autonomous, allowing them to navigate deep ocean environments where human divers cannot go. Common types of subsea vehicles include remotely operated vehicles (ROVs) and autonomous underwater vehicles (AUVs). ROVs are controlled by operators on the surface, while AUVs can perform tasks independently. These vehicles are equipped with cameras and sensors to collect data, making them essential tools for industries like oil and gas, marine biology, and oceanography.
