The story of Fetch

Fetch is an autonomous underwater vehicle (AUV) developed by Professor Mark Patterson of the Virginia Institute of Marine Science (VIMS). Diving down to 1,000 feet for up to 4 hours, the robot can measure water quality (oxygen, salinity, temperature, pH), map the ocean floor, and estimate fish populations. High-frequency sonar combined with a video camera allows Fetch to recognize and remember what it sees—even identifying fish by species.
