Unmanned underwater vehicles play an important role in underwater exploration and research. These vehicles are designed to withstand diving depths and harsh conditions. Usually controlled by robotic systems, they can perform tasks such as underwater imaging, data collection and sampling. Unmanned underwater vehicles are used in deep-sea research, ocean geology studies, marine biology research and undersea exploration. These vehicles do not require humans to operate in harsh and dangerous underwater environments, so they offer great advantages in terms of both safety and efficiency. Unmanned underwater vehicles have great potential for future exploration and scientific research.
