Failed localization
Successful localization
Figure 9.10. In a failed localization, the robot cannot determine a position where the red lines (laser scanner
data) align with the black lines on the map. When the robot can localize itself, it determines a cluster of likely
positions, indicated in the images above as blue dots.
To make sure the robot can localize itself well using particle filtering, consider the following
when creating a map.
•
There must be unique and distinguishable static landmarks on the map that are easily
recognizable. A landmark is a permanent structure that the robot can use to orient itself,
such as corners, doorways, columns, and shelves.
