Embodiment approach 1

[0026] figure 1 It is a figure for demonstrating the relationship of the area|region 1, area|region 2, and a boundary in Embodiment 1.

[0027] Self-propelled cleaning device 1 is with rechargeable battery 16 (referring to image 3 ) is the power source and performs the cleaning function while autonomously walking. In addition, electric power is supplied from the charging device 2 to charge the rechargeable battery 16 . The self-propelled cleaning device 1 is, for example, a cleaning robot.

[0028] The charging device 2 transmits wireless signals such as infrared signals or radio signals. The self-propelled cleaning device 1 receives a signal transmitted from the charging device 2 and measures the reception strength. The self-propelled cleaning device 1 compares the reception strength of the signal received from the charging device 2 with a preset reception strength level.

[0029] Hereinafter, for easy understanding, the preset reception intensity level and the receptio...

Embodiment approach 2

[0075] The self-propelled cleaning device 101 of Embodiment 2 differs from the self-propelled cleaning device 1 of Embodiment 1 in the points described below, and has substantially the same configuration as the self-propelled cleaning device 1 of Embodiment 1 about other points. In addition, in the description of the self-propelled cleaning device 101 of Embodiment 2, the same reference numerals are assigned to the same configuration as that of the self-propelled cleaning device 1 of Embodiment 1, and a part or all of the description of the configuration is omitted.

[0076] Figure 7 It is a figure for demonstrating the relationship of the area|region 1, area|region 2, and a boundary in Embodiment 2.

[0077] Similar to Embodiment 1, the self-propelled cleaning device 101 performs a cleaning function while self-propelled using the rechargeable battery 16 as a power source. In addition, the rechargeable battery 16 is charged from the charging device 2 . The self-propelled cl...

Abstract

A self-propelled cleaning device (1) comprises: a remaining battery power detection unit (17) that detects the remaining battery power of a rechargeable battery (16); a reception strength measurementunit (12) that measures the reception strength of a wireless signal received from a charging device (2); a prescribed value setting unit (13) that sets a prescribed reception strength level; and a traveling area determination unit (14) that, in accordance with the remaining battery power, the reception strength, and the prescribed reception strength level, determines at least one of a cleaning area and a traveling area for the self-propelled cleaning device. If the remaining battery power is greater than or equal to a first prescribed value, the traveling area determination unit determines atleast one of the cleaning area and the traveling area while prioritizing an area in which the reception strength is lower than the prescribed reception strength level over an area in which the reception strength is high. Thus, while the remaining battery power is greater than or equal to the prescribed value, the self-propelled cleaning device can be made to travel while prioritizing an area thatis distant from the charging device.

Description

technical field [0001] The present invention relates to a self-propelled cleaning device for cleaning by self-propelled walking, a control method and a program for the self-propelled cleaning device. Background technique [0002] A cleaning robot as an example of a self-propelled cleaning device includes a cleaning mechanism, a moving mechanism such as wheels, and a rechargeable drive battery, and autonomously cleans the floor of a home. The capacity of rechargeable batteries is limited. Therefore, when the remaining battery level of the rechargeable battery becomes equal to or less than a predetermined value, the cleaning robot returns to the charging device for charging. [0003] At this time, the cleaning robot receives signals such as infrared signals or radio signals sent by the charging device, and judges the relative distance from the charging device and the direction of the charging device based on the strength of the received signal and the direction in which the s...
