Abstract
An automatic moving device and a control method therefor. The automatic moving device comprises a battery pack providing power. The automatic moving device can work within a working area and automatically return to a charging station for charging. The control method comprises the following steps: monitoring the power level of the battery pack; if the power level of the battery pack is less than or equal to a preset power level, initiating an action of returning the automatic moving device to the charging station; and after a preset time period, stopping the travel. By setting a preset time period simultaneously with initiating a return action, and executing a return action within the preset time period, the control method prevents damage to the battery pack from over-discharging caused by the automatic moving device continually returning, thus achieving the effects of protecting the battery pack and extending the life thereof.
