( Mapping ) Robot need to map the positions of objects that it encounters in its environment (Robot position known) (SLAM) Robot simultaneously maps objects that it encounters and determines its position (as well as the position of the objects) using noisy Movie4 Localization Tracking Bounded uncertainty Can flip into kidnapping problem Global Localization Initially huge uncertainties Degenerates to tracking Kidnapping Problem Unexpected global localizationTrackingGlobalLocalizationKi dnapped5 Representing RobotsPosition of robot is represented as a triple consisting of its xt, ytcomponents and its heading t.
