The present disclosure relates to creating a map by identifying a moving object, and a robot implementing the method, and the method comprises, by a sensing unit of a robot, sensing a first object located outside the robot, by a control unit of the robot, calculating mobility of the sensed first object, and storing sensed information and sensed time information of the first object in a map, as a fixed object, when the mobility of the first object calculated by the control unit of the robot is lower than a preset reference.
