To see like a desert ant, Antbot is using a surprisingly simple sensor,
known as a celestial compass.

And it turns out that Antbot can also manage incredible accuracy,
especially given how simple its sensing technique is.

Both are computationally and energetically expensive, but Antbot's sensors are much less intensive-
remember, it's just two pixels watching for UV polarized light.

In outdoor experiments, Antbot managed to travel almost 50 feet, yet divine
its way back to its starting point with an accuracy of less than half an inch.

Researchers at the Aix-Marseille University in France report today in Science Robotics that they have engineered a six-legged robot,
named Antbot, to find its way just like a desert ant.
