Chinese Scientists Develop Robot Fish that Gobble Up Microplastics Robot fish that “eat” microplastics may one day help to clean up the world’s polluted oceans, says a team of Chinese scientists from Sichuan University in southwest China. Soft to touch and just 1.3 centimeters (0.5 inch) in size, these robots already suck up microplastics in shallow water. The team aims to enable them to collect microplastics in deeper water and provide information to analyze marine pollution in real time, said Wang Yuyan, one of the researchers who developed the robot. “We developed such a lightweight miniaturized robot. It can be…
