Leonard and Durrant-Whyte [1991] summarized the general problem of mobile robot navigation by three questions: “Where am I?,” “Where am I going?,” and “How should I get there?.” This report surveys the state-of-the-art in sensors, systems, methods, and technologies that aim at answering the first question, that is: robot positioning in its environment. Perhaps the most important result from surveying the vast body of literature on mobile robot positioning is that to date there is no truly elegant solution for the problem. The many partial solutions can roughly be categorized into two groups: relative and absolute position measurements. Because of the lack of a single, generally good...
