Underwater robotics involves the design and use of robots that operate beneath the surface of water. These robots can be remotely operated or autonomous, allowing them to perform tasks such as exploration, data collection, and maintenance in environments that are difficult or dangerous for humans to access. They are commonly used in fields like marine biology, oceanography, and underwater construction. These robots often come equipped with various tools and sensors, enabling them to gather information about underwater ecosystems, inspect underwater structures, or assist in search and rescue operations. Notable examples include ROVs (Remotely Operated Vehicles) and AUVs (Autonomous Underwater Vehicles), which are essential for scientific research and industrial applications.
