Abstract
A determination on whether or not a local device position and a map contain an error is made. A position measurer of an autonomous movement device measures a local device position. A map memory stores the created map. A position estimator estimates the local device position. A determiner determines whether or not a difference between the measured position by the position measurer and the estimated position by the position estimator is within a predetermined error range. A map editor edits the stored map in the map memory when the determiner determines that the difference is out of the predetermined range.
