Range-free qualitative navigation

Abstract

Some recent algorithms developed for qualitative navigation that are completely independent of range estimates to landmarks are summarized. Several distinctions that reflect more realistic application of qualitative navigation algorithms to real robots are introduced. These involve the extent to which landmarks can be identified from very different points of view (called the distinctiveness of landmarks), whether or not a compass is allowed, and distinctions between different types of compasses.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
