MOBILE ROBOT AND COURSE ADJUSTING METHOD THEREOF

A mobile robot capable of recognizing its location and adjusting its direction in response to an obstacle in its way includes a running device, an obstacle detecting device for detecting the presence of an obstacle, a location recognizing device, a controlling portion, and a power supply. The location recognizing device includes a first vision camera directed toward the ceiling of a room and a first vision board. The first vision camera recognizes a base mark on the ceiling. The first vision board processes an image from the first vision camera and transmits the image data to the controlling portion. The obstacle detecting device includes a line laser for emitting a linear light beam toward the obstacle, a second vision camera for recognizing a reflective linear light beam from the obstacle, and a second vision board for processing image data captured by the second vision camera.
