A group of scientists from the University of Vermont, Tufts University, and Harvard University used stem cells from African clawed frog embryos to create small living beings known as xenobots in January 2020. The xenobots, which are less than 0.04 inches across, can navigate on their own, connect with one another, and repair themselves from injuries, making them the world’s first living robots. However, after more than a year, the computer-created creatures have started to do “something that’s never been seen before.” The xenobots would wander about their environment looking for solitary cells, according to the experts.
