How the first ‘living robots’ are able to walk

1

Scientists use an evolutionary algorithm to create thousands of random designs, simulating passive skin cells and heart cells which contract

Simulated

passive cells

Simulated

contractile

cells

Three different configurations of simulated cells

2

The algorithm asks the designs to achieve a task assigned by the scientists – like walking in one direction

Successful simulation walks

The most promising designs are built from living cells scraped from frog embryos
