Scientists claim to have developed the first walking robot that can explore its environment and find its way home without GPS or mapping, opening new avenues for the navigation of autonomous vehicles.

Ants use polarised light and ultraviolet radiation to locate themselves in space.
AntBot copies the desert ants’ exceptional navigation capacities, allowing it to explore without using Global Positioning System (GPS), researchers said.

It is equipped with an optical compass used to determine its heading by means of polarised light, and by an optical movement sensor directed to the Sun to measure the distance covered.
Weighing only 2.3 kg, this robot has six feet for increased mobility, allowing it to move in complex environments, precisely where deploying wheeled robots and drones can be complicated.
