Researchers create world’s first-ever ‘living robots’

Researchers from the University of Vermont and Tufts University’s Allen Discovery Center have created the world’s first living, self-healing robots using stem cells from frogs.

Named xenobots after the African clawed frog (Xenopus laevis) from which they take their stem cells, the machines are less than a millimeter (0.04 inches) wide — small enough to travel inside human bodies.
This robot can walk and swim, survive for weeks without food, and work together in groups.

Xenobots don’t look like traditional robots — they have no shiny gears or robotic arms. Instead, they look more like a tiny blob of moving pink flesh. The researchers say this is deliberate — this “biological machine” can achieve things typical robots of steel and plastic cannot.
