In July 2022, scientists announced they had discovered over 30 new species of aquatic life from 10,000 feet below sea level. The key to this discovery? The use of underwater robots, which made it possible to explore where humans can't survive. Types of ocean exploration robots include underwater ROVs, humanoid robots, and biomimetic robots. Besides uncovering new species, underwater robots could help with climate change research, deep sea mining, underwater archaeology, and more.
