Scientists made tiny xenobots out of frog cells. Now they say those robots can reproduce.

Life finds a way, and the same goes for even robots, according to a group of scientists who say the first living robotic life forms can reproduce. In January 2020, a team of scientists from the University of Vermont, Tufts University and Harvard University took stem cells from African clawed frog embryos and formed them into tiny living creatures called xenobots. The xenobots, which are less than 0.04 inches wide, were able to move on their own, communicate amongst each other and heal themselves from an injury, making them the first-ever living robots. But over one year later, the computer-designed creatures have begun to do "something that's never been observed before." What the team of scientists discovered was the xenobots would move around their environment and find single cells.
