Abstract: A method and apparatus for relocation of a mobile robot is provided. The relocation method includes the steps of generating a fingerprint based on a previously built magnetic field map, and if the mobile robot is determined as being failed in localization, relocating a location of the mobile robot based on the generated location fingerprint. The step of generating the location fingerprint includes the step of generating the location fingerprint based on the magnetic field map and location measurement values for the mobile robot that are previously measured by a radio source.
