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