Abstract
A method of navigating an autonomous mobile device to a base station is provided. In the method, when a detector detects a navigating signal sent out by the base station, the mobile device rotates in a first direction until the detector fails to detect the navigating signal, and a first time point is set at this time. Then, the mobile device rotates in a second direction opposite to the first direction until the detector fails to detect the navigating signal, and a second time point is set at this time. Afterward, the mobile device rotates in the first direction by a time computed based on the first and second time points to make the detector face the base station, and then, moves toward a direction pointed by the detector.
