Photovoltaic board cleaning robot and control method thereof

The invention relates to the technical field of photovoltaic board cleaning robots and particularly provides a photovoltaic board cleaning robot and a control method thereof. The control method of thephotovoltaic board cleaning robot comprises the steps that whether the photovoltaic board cleaning robot meets an obstacle or not is judged; and if yes, the rotating direction of a rolling brush is adjusted to be consistent with the advancing direction of the photovoltaic board cleaning robot. The photovoltaic board cleaning robot comprises a detecting unit, a control unit and an execution unit,wherein the detecting unit is used for detecting the rotating speed and load current of a rolling brush motor, the control unit is used for receiving data of the detecting unit, judging whether the photovoltaic board cleaning robot meets the obstacle or not and outputting a control instruction, the execution unit comprises the rolling brush and the rolling brush motor, and the rolling brush motorreceives the control instru
