US Scientists have succeeded in building the world’s first living robots. The life forms, denotes the scientists can reproduce that too in a way not seen in plants and animals.

Scientists at the Universities of Vermont, Harvard and Tufts are behind this new discovery. These robots called Xenobots, can self-replicate. The robots are created from the stem cells of the African clawed frog (Xenopus laevis), also from which the robots take its name. They are less than a millimeter, i.e. 0.04 inches wide.

These tiny living biological robots were first unveiled in 2020 by the same scientists. Their ability to move, work together and heal themselves was then demonstrated.

The robots are called as the first living machine by their manufacturer. Xenobots are not just a mechanical robot that is commonly seen, nor are they an existing species. They are living programmable machines.
