World’s first living robots can now reproduce, scientists say

Bongard said they found that the xenobots, which were initially sphere-shaped and made from around 3,000 cells, could replicate. But it happened rarely and only in specific circumstances. The xenobots used “kinetic replication” — a process that is known to occur at the molecular level but has never been observed before at the scale of whole cells or organisms, Bongard said.


The US scientists who created the first living robots say the life forms, known as xenobots, can now reproduce — and in a way not seen in plants and animals.

Formed from the stem cells of the African clawed frog (Xenopus laevis) from which it takes its name, xenobots are less than a millimeter (0.04 inches) wide. The tiny blobs were first unveiled in 2020 after experiments showed that they could move, work together in groups and self-heal.

Now the scientists that developed them at the University of Vermont, Tufts University and Harvard University’s Wyss Institute for Biologically Inspired Engineering said they have discovered an entirely new form of biological reproduction different from any animal or plant known to science.
