APPARATUS AND METHOD FOR PROVIDING ACCURACY OF ROBOT LOCATION INFORMATION BY USING SENSOR
First Claim
Patent Images
1. An apparatus of providing an accuracy of robot location information by using a sensor, the apparatus comprising:
- a robot location information generator configured to generate external location information, internal location information, and integrated location information that includes the external location information and the internal location information,wherein the external location information is generated by calculating a robot location and a sensor zero value by using one or more sensors being located outside of the robot, and modifying the robot location by using the calculated robot location and the calculated sensor zero value, andwherein the internal location information is generated by receiving map information from database, and comprises the calculated robot location on the map by using one or more sensors included in the robot; and
a calculator configured to receive the integrated location information, match the received integrated location information to the map information, and calculate accuracy of the robot location based on a similarity of the robot location between the received integrated location information and the map information.

Abstract
An apparatus and method for providing an accuracy of robot location information. The apparatus may include a robot location information generator and a robot location accuracy calculator, through which the accuracy of location information of itself that the robot recognizes is provided so as to prevent crashes and negligent accident, which are caused by a difference between a robot'"'"'s actual location and movement path and a location and movement path of itself that the robot recognizes
