A method for recognizing a location of a robotic device includes collecting first environmental data corresponding to a first current location of the robotic device, generating a first location signature based on the first environmental data, driving the robotic device to enter a standby mode at a first time, driving the robotic device to wake up from the standby mode after a predetermined time elapses at a second time after the driving the robotic device to enter the standby mode, collecting second environmental data corresponding to a second current location of the robotic device, generating the second location signature generated based on the second environmental data, comparing the first and second location signatures, and determining whether a location of the robotic device has been changed between the first and second times based on a comparison result between the first and second location signatures.
