Abstract

A system and method for identifying objects existing in a space. The system includes a mobile robot obtaining object identification information of each object in the space and transmitting the object identification information, and a remote control unit receiving the object identification information, identifying each object based on the object identification information, and allocating an identifier to each identified object.

Claims

1. A system for identifying objects existing in a space, the system comprising:

a mobile robot obtaining object identification information of each object in the space and transmitting the object identification information; and

a remote control unit receiving the object identification information, identifying each object based on the object identification information, and allocating an identifier to each identified object,

wherein the remote control unit comprises;

a wireless transceiver receiving the object identification information from the mobile robot;

a map processor identifying each object based on the object identification information and allocating the identifier to each object; and

a user interface creating an object map using the identified object and its identifier and displaying the map to a user.

2. The system of claim 1, wherein the object identification information comprises width information of each object.

3. The system of claim 1, wherein the object identification information comprises corner information of each object.

4. The system of claim 1, wherein the object identification information comprises height information of each object.

5. The system of claim 1, wherein the mobile robot comprises:

a traveling unit moving the mobile robot;

an identification information measurer measuring the object identification information;

a controller controlling the traveling unit according to the object identification information and outputting the object identification information; and

a wireless transceiver transmitting the object identification information output from the controller to the remote control unit.

6. The system of claim 1, wherein the map processor has functional characteristic information and spatial characteristic information of each object and allocates the identifier to each object based on the functional characteristic information and spatial characteristic information.

7. The system of claim 1, wherein the user interface displays the identifier in text on the object map.

8. The system of claim 1, wherein the user interface displays the identifier in an image icon on the object map.

9. The system of claim 1, wherein the user interface comprises an input device allowing the user to directly allocate the identifier to each object on the object map.

10. The system of claim 1, wherein the user interface displays the objects in different colors on the object map.
