Abstract: A robot vacuum cleaner and a control method therefor are disclosed. A robot vacuum cleaner according to an embodiment of the present invention comprises an acceleration change sensor module and a distance sensor module. Each piece of detected information is transmitted to an obstacle-passing information calculation module. The obstacle-passing information calculation module uses each piece of transmitted information so as to calculate information about whether an obstacle is present on one side of the robot vacuum cleaner and information about whether the robot vacuum cleaner can pass the obstacle on the one side. When the inability of the robot vacuum cleaner to pass the obstacle on the one side is calculated, a power module is driven so that the robot vacuum cleaner avoids the obstacle. Therefore, the robot vacuum cleaner can be prevented from going on an obstacle such as a carpet. In addition, the robot vacuum cleaner can be prevented from passing an obstacle such as a door sill so as not to leave a cleaning area.

Abstract: A robot cleaner and a control method thereof are disclosed. A robot cleaner, according to an embodiment of the present invention, comprises: a tilt sensor module; a distance sensor module; and a light amount sensor module. Each piece of sensed information is transmitted to a lifting information calculation module. The lifting information calculation module calculates information on whether the robot cleaner is lifted, by using each piece of the transmitted information. If it is calculated that the robot cleaner is lifted off a floor, a power module is stopped. In addition, if it is calculated that the robot cleaner is not lifted off the floor, the power module is driven. Accordingly, when a user lifts the robot cleaner, injuries to the user caused by operation of a drive module can be prevented.
