One of the fundamental abilities required in autonomous mobile agents is the one of homing. Natural agents like ants solve this problem by mainly using dead-reckoning mechanisms within an egocentric frame of reference. Here we present a biologically inspired orientation mechanism, an adaptive light compass, that was used for homing in ”Myrmix”, a mobile robot equipped with infrared and ambient light...
The ability to navigate in a complex environment is crucial for both animals and robots. Many animals use a combination of different strategies to return to significant locations in their environment. For example, 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 on a straight line. The three main strategies...
Central-place foragers like bees use landmark-based information in order to return to important locations. Experiments revealed that the insects store a ''snapshot image'' of the surroundings of the target location and derive a home direction by comparing current image and snapshot. A corresponding algorithmic model, the so-called ''snapshot model'', was proposed by Cartwright and Collett (J. Comp...
