Robotic fishes

Soon, the water in Gijon, a harbor in Northern Spain will be monitored by robotic, battery-powered fish. These mechanical, articulating sea creatures were designed and tested by the Robotics Department at the University of Essex. At a cost of $3.6 million, through a European Union grant, these fish will test the water for oxygen levels, detect oil slicks and other contaminants pumped into the water. This is the first monitoring program of it’s kind, and the retrieved data could be very important, with implications for global warming and the state of our water sources
