摘要:
There is provided a mobile robot including a light source, an image sensor and a processor. The image sensor respectively captures bright image frames and dark image frames corresponding to the light source being turned on and turned off. The processor identifies that the mobile robot faces a cliff when a gray level variation between the bright image frames and the dark image frames is very small, and controls the mobile robot to stop moving forward continuously.
