A China-made robofish has "swum" in antarctic waters for the first time collecting data for polar water quality research, the makers of the submersible said Friday.
The robofish, a fish-shaped device for polar ocean exploration, had a "steady and good swim" in water at a temperature of minus 40 degrees celsius, while its sensor collected real-time water data, according to the Beijing University of Technology.
The swimming tests were conducted from October to April this year. The simulated fish also dived in the arctic in 2012.
The tests provided material for tudy of polar waters and will be an important reference for design of more advanced robofish, the university said.
