    Abstract: In the conventional cleaning robot, by mainly using each supersonic waves sensor having a sensing range as ±30° in consideration of an appropriate sensitivity, when four supersonic waves sensors are installed at a cleaner main body, a sensing range as 240° is obtained, and accordingly it is impossible to observe surroundings of the cleaner thoroughly. In order to solve the above-mentioned problem, a position information recognition apparatus for a cleaning robot in accordance with the present invention includes a fixed plate installed at a cleaner main body; a main motor fixedly installed at the fixed plate in order to generate a rotational force; a rotational cylinder combined with a rotational axis of the main motor so as to be rotated at a certain angle; and plural position information sensors installed at the rotational cylinder at a certain angle in order to sense surroundings. By installing several supersonic waves sensors performable left/right rotation at regular intervals, observation region can be greatly increased, and accordingly it is possible to improve efficiency by eliminating unnecessary rotational motion of the cleaner main body in position recognition and distance compensation.

    Abstract translation: 在传统的清洁机器人中，考虑到适当的灵敏度，通过主要使用具有±30°的感测范围的每个超声波传感器，当在吸尘器主体上安装四个超声波传感器时，获得240°的感测范围， 因此不可能彻底地观察清洁剂的周围环境。 为了解决上述问题，根据本发明的清洁机器人的位置信息识别装置包括安装在吸尘器主体上的固定板; 主电动机固定地安装在固定板上以产生旋转力; 与主电动机的旋转轴组合的旋转圆筒，以一定角度旋转; 以及多个位置信息传感器，以一定角度安装在旋转圆筒上，以便感测周围环境。 通过以规则的间隔安装多个超声波传感器进行左/右旋转，观察区域可以大大增加，因此通过在位置识别和距离补偿中消除吸尘器主体的不必要的旋转运动，可以提高效率。

    Abstract: A robot cleaner includes: a suction unit (60) installed at a cleaner body (1), for sucking dirt on a floor; a driving unit (50) for moving the cleaner body; a sensing unit (100) mounted at the cleaner body (1), for sensing a depressed portion and a stepped portion such as a doorsill of a floor; and a control unit (10) receiving a signal of the sensing unit, for controlling the driving unit (50) to allow the cleaner body (1) to avoid the depressed portion and the stepped portion, thereby correctly sensing the depressed portion or the stepped portion of the floor and avoiding such a portion. Accordingly, the cleaning operation is stably carried out.
