European scientists are testing robot “fish” which can detect pollutant at the Northern Spanish port of Gijon on Tuesday, according to Reuters.
This new technology can improve the speed of detecting pollutant significantly, from weeks to seconds. The current method requires people to take sample collection of water to a shore based laboratory, but this robot fish can provide real-time information.
