‘Mother’ robot builds ‘children’ models to make each generation better

The roboticists built a ‘mother’ machine that independently builds its own ‘children’ and tests which ones perform best at certain tasks.

This ‘mother’ then uses the results to inform the design of the next ‘child’, so that preferential traits are passed down from one generation to the next – similar to how natural selection works in animals.
