Abstract
Disclosed is a mobile robot, wherein obstacles are efficiently sensed by combining obstacle sensing signals output from different sensing units having different sensing areas and thus a drive of the mobile robot is controlled to avoid the obstacles. The mobile robot according to the present invention comprises a plurality of sensing units comprised of different sensors having different sensing areas for sensing obstacles in the traveling direction, and a microprocessor for outputting control signals according to avoidance instruction corresponding to a combination of sensing signals from the different sensors to avoid the obstacles. Accordingly, the present invention has an advantage that it is possible to recognize the obstacles with a high reliability and to avoid the obstacle efficiently, compared to when sensing the obstacles with a single kind of sensor.
