2、tic automatons are only 15mm long.Yet,they can travel quite quickly as they clean.They move by flashing a laser on and off in their tails.It causes the tail to flap side to side which propels the fish through the water.As they swim along,any nearby microplastics get drawn towards the robots and stic
3、k to them.Not only is their shape inspired by marine life so is the material they are made out of.Mother-of-pearl is found on the inside surface of clam shells.It was the inspiration for the material the team used for their robo-fish.As well as attracting microplastics,the material can even heal its
4、elf after being cut.Microplastics are one of the largest environmental problems we face.They have been found nearly everywhere.Theyve been found in our oceans,on top of mountains,in some of the food we eat and even in the stomachs of some marine animals.One of the biggest problems with microplastics
5、 is,because of their size,they are difficult to clean up.This is especially true of microplastics in the ocean.The scientists hope that their tiny fish-shaped robots can one day help tackle this global problem.At the moment,the robo-fish are something called proof of concept.It just means that the s
6、cientists were able to make something that proves that their idea worked.Now that the team has shown that their idea works,they are going to keep working on it.They hope to create new versions that can dive deeper and absorb more microplastics.Daily News Technology World News 5th July 2022Glossarybi
