Phot of AntBot

Ants are able to use polarized light and ultraviolet radiation to locate themselves in space. AntBot mimics this ability to explore its environment randomly and go home automatically, without GPS or mapping.

AntBot is equipped with an optical compass used to determine its heading by means of polarized light, and by an optical movement sensor directed to the Sun to measure the distance covered. It features precision of up to 1 cm after having covered a total distance of 14 meters.
