摘要： To improve the accuracy of the self position estimation of a mobile robot. A robot measures a distance to an object in the mobile environment by using a range sensor. An environmental map storage unit stores an environmental map containing a plurality of map data each corresponding to a respective one of a plurality of measurement directions from which a point in the mobile environment is to be observed. A self position estimation unit selects a map data corresponding to a measurement direction in which a distance to the object is measured by the range sensor from the plurality of map data. Then, the self position estimation unit estimates a self position of the mobile robot based on the selected map data and range data obtained by the range sensor.
