Biomimicry: Ant movements inspire tunnel-digging robots | Biomimicry |

Biomimicry is a great tool to solve problems. Rather than reinvent the wheel, we can often look at the solutions that nature has come up with over millions of years of trials & errors. For example, the study of how ants can so quickly move underground and dig relatively stable tunnels in all kinds of soil can teach scientists and engineers a lot, some of which might be quite useful to make robots that could do search & rescue missions or explore hard to access corners of the Earth (equipped with the proper sensors, they could be used for all kinds of environmental monitoring jobs).
