Navigation in desert ants: the robotic solution

摘要

The desert ant Cataglyphis is able to explore its desert habitat for hundreds of meters while foraging and return back to its nest precisely and in a straight line. With a body of less than 10 mm and a brain of less than one cubic millimeter they provide a challenge for hi-tech engineers. In this article, we give an overview of our attempts to model parts of its navigation behavior using robots and computer simulations. Inspired by the insect's navigation system we have developed mechanisms for path integration and visual piloting that were successfully employed on the mobile robot Sahabot 2.
