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.

Description

[0001] This U.S. non-provisional patent application claims priority to Korean Patent Application 2005-0039460 filed May 11, 2005 under 35 U.S.C. §119, the contents of which are incorporated herein by reference. technical field [0002] The present invention relates to mobile robots, and more particularly, to techniques for efficiently sensing obstacles based on obstacle sensing signals provided from various sensors, and controlling driving of a mobile robot to avoid obstacles based on the sensing results. Background technique [0003] Robots are developed for industrial purposes and as factory automation systems. In addition, robots are used to collect or collect information on behalf of humans in extreme environments that humans cannot tolerate. This field of robotics has been continuously developed, although only recently in the state-of-the-art space development industry, and in recent years, human-friendly domestic robots have been developed. A prime example of a human-...
