Unmanned underwater vehicles (UUVs) are robotic devices designed to operate underwater without a human crew. They are used for various purposes, including scientific research, environmental monitoring, and military applications. UUVs can be remotely operated or programmed to follow specific paths, allowing them to explore deep-sea environments and gather data. These vehicles come in different shapes and sizes, ranging from small, portable models to larger, more complex systems. UUVs are equipped with sensors and cameras to collect information about underwater ecosystems, shipwrecks, and geological formations. Their versatility makes them valuable tools for organizations like NOAA and the U.S. Navy.
