Abstract: According to the present disclosure, when a mobile robot travels, if the learning information of the avoiding mark which is machine-trained by the mobile robot corresponds to a mark around the target object sensed by the mobile robot, the mobile robot can avoid the sensed avoiding mark. That is, the mobile robot may collide with an object which needs to be avoided while traveling. Therefore, when an avoiding mark which is formed of at least any one of a different color or a different material from the floor of the driving area is disposed around an object to be avoided or an area to be avoided and the avoiding mark is sensed, the mobile robot autonomously avoids the object or the area to be avoided to be prevented from colliding with the object which needs to be avoided or traveling in the area to be avoided.
