    • Disclosed are a mobile robot and a controlling method thereof. The mobile robot comprises: a case; and a sensor unit having two or more sending portions and two or more receiving portions arranged on an outer surface of the case separately and alternately. The plurality of sending portions and receiving portions are arranged in an alternating manner, thereby having a directivity. Also, since signals received through the receiving portions are judged based on a reference value, an area unallowable to be detected for an obstacle sensing is minimized, which allows an obstacle to be detected more accurately. When the obstacle corresponds to a side wall on the basis of a moving path of the mobile robot, a distance between the side wall and the mobile robot is calculated based on signals received by the receiving portion closest to the side wall. Accordingly, the mobile robot can move with maintaining a constant distance from the side wall.
    • 公开了一种移动机器人及其控制方法。 移动机器人包括:壳体; 以及传感器单元,其具有两个或更多个发送部分和两个或更多个接收部分,分别和交替地布置在壳体的外表面上。 多个发送部分和接收部分以交替的方式布置,从而具有方向性。 此外,由于基于参考值判断通过接收部分接收到的信号,所以不容易被检测用于障碍物感测的区域被最小化,这允许更准确地检测障碍物。 当障碍物基于移动机器人的移动路径对应于侧壁时,基于最靠近侧壁的接收部分接收的信号来计算侧壁和移动机器人之间的距离。 因此,移动机器人可以在与侧壁保持恒定距离的情况下移动。

    • A bumper device of a robot cleaner, and a robot cleaner equipped with the bumper device are disclosed. The bumper device of a robot cleaner includes: a bumper housing coupled to cover an outer circumferential surface of a main body of a robot cleaner, made of a material for restraining an expansion, and having an internal passage; an air tube insertedly installed inside the bumper housing so as to be expandable along the internal passage; and a sensing unit for sensing expansion of the air tube. Even if an impact is applied to any position of front, side and rear surfaces of the main body, it can be lessened in its transfer to the robot cleaner.
    • 公开了一种机器人清洁器的保险杠装置和装备有保险杠装置的机器人清洁装置。 机器人清洁器的保险杠装置包括:保险杠壳体,其联接以覆盖由用于限制膨胀的材料制成并具有内部通道的机器人清洁器的主体的外周表面; 插入地安装在保险杠壳体内部以便沿着内部通道可扩张的空气管; 以及用于感测空气管的膨胀的感测单元。 即使对主体的前侧,后侧和后表面的任何位置施加冲击,也可以减少其转移到机器人清洁器。

    • An apparatus and a method for correcting a position of a mobile robot includes a position notifying unit, installed at a predetermined position, that generates and transmits a signal indicative of the predetermined position. The mobile robot includes a position signal detector, installed at a predetermined position of the mobile robot, that detects a signal; and a control unit, installed at a predetermined position of the mobile robot, that corrects a position of the mobile robot on the basis of pre-stored position information corresponding to the detected position signal, so that a position error that is generated when the mobile robot moves is corrected.
    • 用于校正移动机器人的位置的装置和方法包括安装在预定位置的位置通知单元,其产生并发送指示预定位置的信号。 移动机器人包括安装在移动机器人的预定位置的位置信号检测器,其检测信号; 以及安装在移动机器人的预定位置的控制单元,其基于与所检测到的位置信号相对应的预先存储的位置信息来校正可移动机器人的位置,使得当移动机器人的位置错误 机器人移动被纠正。
