A new robot can create baby robots. It's like science fiction. In 2020, scientists made the world's first "living" robot. It came from stem cells of an African frog. The new "xenobots" are less than one millimetre wide. They work in groups, and repair themselves. They don't look like robots. They are a machine-animal hybrid.

Researchers created a C-shaped robot. The inside of the "C" is the xenobot's mouth. It collects cells in its mouth and these become baby xenobots. This new technology could change our lives. They could repair our body and clean up plastic in the oceans. There are many benefits, but people are worried the robots can have babies.
