Scientists say that new kind of robot can reproduce - it can create baby robots. This is example of science fiction becoming science fact. The scientists, from Universities of Vermont, Tufts and Harvard, created world's first "living" robots. They are called "xenobots". Scientists created them in 2020 from stem cells of African frog. Its scientific name - "xenopus laevis" - gave xenobot its name. The xenobots are less than millimetre wide. They can move, work together in groups and self-heal. Although they are not what we imagine robots to be, scientists say they are technically robots. They are machine-animal hybrid. The scientists say xenobots are " entirely new life-form".
scientists explained that bots reproduce because of their shape. Researchers used artificial intelligence (AI) to test billions of body shapes. result was C-shaped robot. It was able to find tiny stem cells in petri dish. It gathered cells in its mouth. A few days later, the cells became new, "baby" xenobot. The xenobots are very early technology. However, they could change science, medicine, technology and way we live. They could carry out tasks inside our body to repair damage to organs. They could also help environment by attacking micro-plastics in our oceans, or by cleaning up oil spills. Despite possible benefits, some people are worried about robots that can reproduce
