Unmanned Underwater Vehicles (UUVs) are robotic devices designed to operate underwater without a human crew. They are used for various purposes, including ocean exploration, environmental monitoring, and military applications. UUVs can be remotely operated or programmed to follow specific paths, allowing them to gather data and perform tasks in challenging underwater environments. 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 marine life, underwater structures, and ocean conditions. They play a crucial role in advancing our understanding of the world's oceans and supporting research efforts related to marine biology and oceanography.
