MOVING LIMITATION SYSTEM AND METHOD OF MOBILE ROBOT

摘要

The present invention relates to a system and a method for controlling the movement of a movable robot and, more specifically, to a system and a method for controlling the movement of a movable robot in order to make the movable move within a limited region without a separate beacon by using a floor sensor. Therefore, the present invention provides the system for controlling the movement of the movable robot, which includes at least one reflection region and at least one absorption region; entry preventing patterns on which the reflection region and the absorption region are alternately arranged; and the movable robot avoiding the entry preventing patterns when the entry preventing patterns are sensed in driving. Furthermore, the present invention includes a first step that a light emitting unit emits infrared rays to a floor; a second step that a light receiving unit measures the amount of the infrared rays reflected by the floor; a third step that an A/D conversion unit digitalizes the measured amount of the infrared rays; a fourth step that a pattern recognizing unit senses the entry preventing patterns by using the digitalized amount of the infrared rays; and a fifth step that a control unit controls the movable robot to make the movable robot avoid the entry preventing patterns.
