Abstract
There is provided a cleaning robot including a first light source, a second light source, an image sensor and a processor. The processor is used to calculate an image quality of an image frame captured by the image sensor when the second light source is being turned on. The processor then determines whether to switch the second light source back to the first light source according to the image quality to accordingly identify the material of an operation surface.
