Robot localization is the problem of estimating robot coordinates with respect to an external
reference frame. In the common formulation of the localization problem, the robot is given a
map of its environment, and to localize itself relative to this map it needs to consult its
sensor data. The effectiveness of a solution to the localization problem in an unstructured
environment strongly depends on how it copes with the uncertainty affecting robot
perception.
