Abstract: An environment information acquisition unit acquires a signal state of a traffic light. A self-position estimation unit estimates a self-position of the autonomous moving object. A traveling route decision unit calculates a first time necessary to move along a first route from the self-position to an end point of a crosswalk and a second time necessary to move along a second route from the self-point to a start point of the crosswalk in a case in which the signal state is changed from blue to red on the crosswalk after a predetermined time or in a case in which the signal state is changed from blue to red, and selects a route corresponding to a time smaller between the first time and the second time. A vehicle control unit controls autonomous movement of the autonomous moving object so that the autonomous moving object moves along the selected route.

Abstract: A mobile robot system includes an outside world sensor, a traveling unit, and a control unit. The control unit is configured to provide a history map data. Based on environment information obtained from the outside world sensor, a mobile object appearance point at which no mobile body exists at present but there is the possibility that a mobile body may appear in the future is recognized. In recognizing a door as the mobile object appearance location, if part of an object being obtained from the outside world sensor and having a width equal to or greater than a predetermined width set in advance belongs to an object movement position recorded in the velocity history map, then the part is recognized as a door.
