Subsea robots, also known as underwater drones or ROVs (remotely operated vehicles), are specialized machines designed to explore and work in deep ocean environments. They are equipped with cameras and sensors that allow them to capture images and gather data from the ocean floor, making them essential for marine research, oil and gas exploration, and underwater construction. These robots can operate at great depths where human divers cannot go, helping scientists study marine life and ecosystems. They can also perform tasks like inspecting pipelines and repairing underwater structures, showcasing their importance in both environmental monitoring and industrial applications.
