Learn about Underwater Robots

Underwater robots, such as remotely operated vehicles and autonomous underwater vehicles, are essential tools for ocean exploration. These robots can explore areas of the ocean that are too dangerous or too difficult for humans to go. Underwater robots come in a variety of shapes and sizes and can be outfitted with numerous sensors and tools to collect extensive amounts of data from deep-sea environments.
