Scientists in the United States have created the world’s first “living machines” — tiny robots built from the cells of the African clawed frog, that can move around on their own.
About:
They have named the millimetre-wide robots “xenobots” — after the species of aquatic frog found across sub-Saharan Africa from Nigeria and Sudan to South Africa, Xenopus laevis.
The xenobots “can move toward a target, perhaps pick up a payload (like a medicine that needs to be carried to a specific place inside a patient) — and heal themselves after being cut.
The “novel living machines” were “neither a traditional robot nor a known species of animal”, but “a new class of artifact: a living, programmable organism”.
