Scientists have created fish-shaped robots to swim around and collect microplastics from the oceans’ nooks and crannies.
Microplastics, tiny plastic particles that can be harmful to marine animals when ingested, settle at the bottom of waterways and are hard to remove from the environment.
Chinese scientists have developed a small, self-propelled robot that can ‘swim’ into the oceans’ hard-to-reach spots and clean them up.
