*Xenobots are tiny machines made out of living parts. The starting ingredient for these bio-robots is frog cells. They are formed from the stem cells of the African clawed frog (Xenopus laevis) from which it takes its name. Xenobots do not have machine parts. Instead, all of their components are biological. For example, a xenobot’s energy comes from the yolk that’s a part of all amphibian eggs, which can power these machines for about two weeks with no added food. To get them to move, scientists can add biological “motors” like muscle or cardiac tissue.*
