1. A control method of a mobile robot, comprising:
a detection step of detecting a movement occurring in an area to be cleaned;
a determination step of determining whether the detected movement is a stored behavior pattern or not; and
a first learning step of learning whether the detected movement is a behavior pattern of causing a foreign material or not when it is determined that the detected movement is not the stored behavior pattern, and
wherein the first learning step comprises:
a temporary storage step of temporarily storing the detected movement;
a temporary cleaning step of cleaning a corresponding area where the movement that is temporarily stored occurs;
an operation step of a foreign-material sensor in the temporary cleaning step; and
a final storage step of storing the movement that is temporarily stored as a behavior pattern of causing a foreign material when a predetermined foreign material is detected by the foreign-material sensor.
