Xenobots: Building the First-Ever Self-Replicating Living Robots

Scientists at UVM, Tufts, and Harvard discovered a new form of biological reproduction—and created self-replicating living robots. Made from frog cells, these computer-designed organisms gather single cells inside a Pac-Man-shaped “mouth”—and release Xenobot “babies” that look and move like themselves. Then the offspring go and do the same—over and over.
