Home network system and method for an autonomous mobile robot to travel shortest path
First Claim
1. A home network system capable of home automation, the home network system comprising:
- a plurality of beacons uniformly arranged at regular intervals over an entire area of a home for obtaining information of a user located in a respective cell coverage area of a corresponding beacon by sensing at least one communication apparatus of the user, the information of the user comprising Radio Frequency Identification (RFID) information of the at least one communication apparatus of the user and for transmitting information of the user obtained from the at least one communication apparatus of the user to a home server;
the home server for receiving the sensing information of the user transmitted from the plurality of beacons, for receiving location information of an autonomous mobile robot, for calculating a travel route along which the autonomous mobile robot can reach the user based on the received sensing information and the received location information of the autonomous mobile robot, and for transmitting the calculated travel route to the autonomous mobile robot via wireless communication; and
the autonomous mobile robot, which is separate from both home server and the plurality of beacons, for receiving the transmitted travel route information, and executing travel to reach the user based on received travel route information,wherein, if the users is sensed at a location where the cell coverage areas of adjacent beacons overlap, the location information of the user is defined as corresponding to a location centered between the adjacent beacons, and wherein, sensing the user includes, if the user is sensed at the location where the cell coverage areas of adjacent beacons overlap, the resulting location information of the user is found along an X-axis and a Y-axis through (XA+(XB−
XA)/2, YA+(YB−
YA)/2), where (XA, YA) is a co-ordinate of one of the adjacent beacons and (XB, YA) is a co-ordinate of another one of the adjacent beacons.

Abstract
Provided are a home network system and a method for an autonomous mobile robot to travel along a shortest travel route. The home network system capable of home automation includes a plurality of beacons for sensing a user located in a cell coverage area and for transmitting resulting sensing information of the user; an autonomous mobile robot for executing travel to reach the user based on provided travel route information; and a home server for calculating a travel route along which the autonomous mobile robot can easily reach the user based on the sensing information of the user transmitted from the beacons, and for providing the travel route to the autonomous mobile robot. Therefore, the autonomous mobile robot may reach the user by the shortest travel route and thus reducing energy loss.
