Abstract
An autonomous moving device includes a travel unit with a wheel driven by a motor and an upper body including an environment-recognition sensor that detects an obstacle in a traveling direction. The upper body includes means that recognize device and obstacle positions, means that evaluates avoidance capability, and means that obtains priority of collision avoidance of an estimated passage area of the obstacle. The upper body further includes a control unit that moves the travel unit to an area where an estimated passage area of an obstacle whose priority of collision avoidance is high that does not overlap an area where the travel unit is located and which is an area where collision can be avoided even if an area where an estimated passage area of an obstacle whose priority of collision avoidance is low overlaps the area where the travel unit is located.
