Abstract: There is provided a self-propelled electronic device that is supplied with power from a charging base installed in a predetermined position and automatically travels to a position away from the charging base, the self-propelled electronic device including: a travelling control unit that makes the self-propelled electronic device move automatically by controlling the rotation of a wheel; a rechargeable battery that supplies power for performing travelling control during the automatic travelling; a charging base searching unit that searches for the position of the charging base; and a control unit; wherein, when the control unit determines that returning to the charging base is required, the control unit performs return processing by which the self-propelled electronic device is made to come to rest and then rotate in a resting state by the travelling control unit and, when the charging base searching unit searches for the direction in which the charging base lies and detects the direction in which the charging

Abstract: A self-propelled vacuum cleaner comprising a housing; traveling members for allowing the housing to travel; cleaning members for cleaning a floor surface; an obstacle detection unit for detecting positions of obstacles present around the housing; and a control unit for controlling the traveling members, the cleaning members and the obstacle detection unit to allow the housing to clean the floor surface while the housing is self-propelled, wherein the control unit controls the obstacle detection unit to detect the positions of the obstacles around the housing and determines a traveling time to clean the floor surface on the basis of the positions of the obstacles.
