  abstract = {Navigation is one of the most fundamental tasks to be accomplished
	by many types of mobile and cognitive systems. Most approaches in
	this area are based on building or using existing allocentric, static
	maps in order to guide the navigation process. In this paper we propose
	a simple egocentric, qualitative approach to navigation based on
	ordering information. An advantage of our approach is that it produces
	qualitative spatial information which is required to describe and
	recognize complex and abstract, i.e., translation-invariant behavior.
	In contrast to other techniques for mobile robot tasks, that also
	rely on landmarks it is also proposed to reason about their validity
	despite insufficient and uncertain sensory data. Here we present
	a formal approach that avoids this problem by use of a simple internal
	spatial representation based on landmarks aligned in an ''extended
	panoramic representation'' structure.},
