Abstract
A moving robot comprises a floor sensing unit comprised of a plurality of transmitters, for which different sensing distances are set, and a single receiver, and, since a floor state is sensed using a plurality of sensors, it is possible to sense a normal floor states, an obstacle or a cliff present on a floor, and a long-distance state at a distance farther than the normal floor state, thereby preventing wrong sensing of a cliff due to an obstacle, and, since whether to keep traveling is set depending on the obstacle and a traveling speed is controlled, even an area previously not allowed to enter due to the wrong sensing may be cleaned and therefore a cleaning area may be increased.
