control module 133 obtains the state of thecleaning robot 130 according to the sensed signal generated by thesense module 132. For example, when a duration in which a variation of the sensed signal generated by thesense module 132 is less than a pre-determined value exceeds to a pre-determined period, this represents that the cleaningrobot 130 is at a fixed place. In one embodiment, the cleaningrobot 130 may be locked at the fixed place.

FIG. 2 is a schematic diagram of an exemplary embodiment of a control method of the invention. First, a magnet module is disposed in a guiding object to form a magnetic field (step S210).

FIG. 3 is a schematic diagram of another exemplary embodiment of the control method of the invention.FIG. 3 is similar toFIG. 2 , except for the addition of steps S340 and S350.

When the duration, which the variation of the sensed signal generated by step S320 is less than the pre-determined value in exceeds to the pre-determined period, this represents that the cleaning robot is at a fixed place. Thus, an external environment of the cleaning robot is sensed to generate a sensing result, and the efficiency of at least one of the cleaning action and the moving action is adjusted according to the sensing result (step S350).
- For example, when the cleaning robot is locked at a fixed place, the moving action is first adjusted to shake the cleaning robot. Then, another sense module is utilized to sense the external environment of the cleaning robot to generate another sensing result. The traveling path of the cleaning robot is adjusted according to the other sensing result such that the cleaning robot leaves the fixed place. Additionally, when the cleaning robot is at a fixed place, the cleaning action is stopped. After the cleaning robot leaves the fixed place, the cleaning action is performed.
- In one embodiment, step S350 utilizes a photo sensor, and the photo sensor senses a reflected light of the external environment of the cleaning robot. In another embodiment, step S350 utilizes an audio sensor to sense a reflected audio wave of the external environment of the cleaning robot.
- When the duration, which the variation of the sensed signal generated by step S320 is less than the pre-determined value in does not exceed to the pre-determined period, this represents that the cleaning robot is not at a fixed place and is operating normally. Thus, step S320 is performed to sense the variation of the sensed signal and then control at least one of the cleaning action and the moving action according to the sensing result. Furthermore, after executing step S350, step S320 is performed to sense the magnet field.
