Method for providing location information of target using mobile robot

PURPOSE: A method for providing location information of a target by using a mobile robot is provided to display a path to a target in the form of augmented reality based on received search information, thereby collecting desired information about an indoor environment. CONSTITUTION: A mobile robot searches an unknown region and constructs a map (S210). A detected target is registered in the map (S220). The mobile robot transmits collected search information to a wearable-type device (S230). The wearable-type device receives the collected search information through wireless communications and displays the received search information in the form of augmented reality through a head-mounted display (HMD) (S240).
