Living Robots Created from Frog Stem Cells

American scientists have developed "living machines" using stem cells taken from African clawed frogs. The scientists created self-propelled robots smaller than one millimeter.

Robots called "Xenobots," described as a new life form never before seen in the world, heal their own wounds and die like living organisms. It is hoped that these robots will be used in areas such as opening clogged blood vessels, clearing microplastics from oceans, or locating and eliminating toxic substances.

'Living programmable organisms'

According to British newspaper Guardian, Michael Levin, Director of the Allen Discovery Center at Massachusetts Tufts University, described the robots they developed as "These are living programmable organisms." Roboticists typically prefer to use metal and plastic to make robots strong and durable. However, Levin and his team made their robots from biological tissues.   Source
