Embodiment approach

[0025] Below, refer to Figure 1 to Figure 3 The self-propelled (vacuum) cleaner 100 according to the embodiment of the present invention will be described.

[0026] figure 1 It is a top view which shows the appearance of the self-propelled (vacuum) cleaner 100 of this embodiment from above. figure 2 It is a bottom view showing the appearance of self-propelled (vacuum) cleaner 100 from below. image 3 It is a perspective view showing the appearance of self-propelled (vacuum) cleaner 100 from obliquely above.

[0027] In addition, self-propelled vacuum cleaner 100 is a cleaning robot that performs cleaning while autonomously moving over a cleaning area such as the floor. Specifically, the autonomous cleaner 100 is a robot cleaner that autonomously travels in a predetermined cleaning area based on an environment map described later, and sucks up garbage existing in the cleaning area.

[0028] Such as Figure 1 to Figure 3 As shown, the self-propelled vacuum cleaner 100 of...

Abstract

A self-propelled vacuum cleaner (100) includes a body, a driving unit (130) that moves and turns the body, and an obstacle detecting unit (an obstacle sensor (173), a range sensor (174), and a camera(175)) for detecting an obstacle around the body. The self-propelled vacuum cleaner further includes a lifting unit (133) for lifting the body from a floor, and a control unit (150) for controlling the driving unit (130) and the lifting unit (133) on the basis of detection results obtained by the obstacle detecting unit. When the depth of an obstacle in the traveling direction of the body is smaller than a predetermined value, the control unit (150) controls the driving unit (130) such that the body avoids the obstacle in a state in which lifting by the lifting unit (133) is released. Meanwhile, when the depth is larger than or equal to the predetermined value, the control unit (150) controls the driving unit (130) such that the body runs on the obstacle in a state in which lifting by thelifting unit (133) is enabled. This configuration improves the reliability of obstacle cleaning.

Description

technical field [0001] The present invention relates to an autonomous walking type vacuum cleaner which cleans while walking autonomously. Background technique [0002] Conventionally, there is known a self-propelled vacuum cleaner provided with a lifting portion that lifts the main body from the ground so as to overcome obstacles such as electric wires (for example, refer to Patent Document 1). [0003] Here, in a state where the main body is lifted by the lifting portion, the distance from the floor to the suction port is wider than normal, so the suction force decreases. For example, when the obstacle is a floor such as a carpet, the self-propelled vacuum cleaner climbs onto the floor while the main body is lifted by the lifter, and then releases the raised state to exert a normal suction force. [0004] However, if the depth of the bedding is narrow in the direction of travel of the self-propelled (vacuum) cleaner, the self-propelled (vacuum) cleaner passes the bedding ...
