MOBILE ROBOT AND OPERATING METHOD THEREOF

摘要

Data within a designated distance from a main body of the mobile robot is accumulated and stored to form a local area map. A traveling direction or a rotating direction is set while avoiding an obstacle around the main body and a path may be readily set. Repetition of unnecessary operation is prevented and thus a traveling velocity based on rapid movement may be improved. Obstacles are readily avoided and cleaning efficiency may be improved.

主权项

1. A mobile robot comprising:
a mobile main body; an optical pattern sensor configured to sense obstacles around the main body; a cleaning unit sucking in foreign substances around the main body during traveling; a controller configured to extract information of the obstacles by analyzing data input from the optical pattern sensor, to set a traveling direction or a traveling path so as to avoid the obstacles, and to control the main body so as to travel to a destination while avoiding the obstacles; and a travel driving unit configured to move the main body according to control instructions from the controller, wherein the controller includes: an obstacle information acquisition unit configured to judge the obstacles and to calculate the positions of the obstacles from data from the optical pattern sensor; and a map generation unit configured to generate a local area map of an environment around the main body based on the information of the obstacles calculated by the obstacle information acquisition unit.
