1. A method for recognizing a location of a robotic device in one or more data centers, comprising: collecting first environmental data corresponding to a first current location of the robotic device in the one or more data centers; 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 at a second time after a predetermined time elapses 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 second location signature with the first location signature; and determining whether a location of the robotic device has been changed between the first and second times based on a comparison result of the second location signature with the first location signature.
