Soft to touch and just 1.3 centimetres 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 analyse marine pollution in real time, said Wang Yuyan, one of the researchers who developed the robot. “We developed such a lightweight miniaturised robot. It can be used in many ways, for...
