Patent ID: 8560120

Claim:
A moving robot, comprising: a traveling device that controls a traveling speed and direction by controlling driving of a motor connected with a plurality of movable wheels; a dust suction device that sucks dust along with air according to a rotational operation of a fan motor that generates a suction force; an obstacle sensor that senses an obstacle within a predetermined distance; an output device that outputs input data and operation state data; a moving body/object sensor that senses movement of an object located within a predetermined distance; and a controller that outputs a control signal to control an operation, wherein when a movement of a certain object is sensed by the moving body/object sensor while the moving robot is traveling, the controller outputs to the traveling device a control signal to control the traveling speed according to pre-set data, and wherein when the movement of the object is sensed by the moving body/object sensor while the moving robot is operated, the controller outputs to the traveling device a control signal to reduce the traveling speed of the moving robot, and outputs to the traveling device a control signal to recover the traveling speed of the moving robot to the previous state when a control command is not input from an external source during a predetermined time period after the traveling speed of the moving robot is reduced.
