Abstract

A robot 20 periodically moves along specified routes in a user'"'"'s living space 1, collecting the ID data items of objects 40 existing in the living space 1. Each object 40 has a radio tag 10, which stores the ID data of the object 40. The robot 20 has a communications unit 26. While the robot 20 is moving, the unit 26 keeps transmitting an electric wave to which the radio tags 10 can respond. Upon receiving the electric wave, each radio tag 10 transmits the ID data of the object 40. The robot 20 receives the ID data and generates property data by adding, to the ID data, the data representing the time and position at which the radio tag 10 has transmitted the ID data. The property data shows what exists where and when. A data-managing apparatus 30 has a meta-data recording unit 31, which converts the property data to meta data. The meta data can be used in various types of data-processing apparatuses.

Claims

1. A data-collecting system for collecting data about objects existing in a specified space, comprising:

radio tags provided on the objects, each storing an ID data item identifying one object;

a robot apparatus which moves in the specified space to collect ID data items stored in the radio tags; and

a data-managing apparatus which manages the ID data items collected by the robot apparatus.

2. A data-collecting system according to claim 1, wherein the robot apparatus comprises:

tag-position determining means for determining a position that each radio tag takes in the specified space, from the position of the robot apparatus; and

property-data generating means for generating property data by adding, to the ID data time stored in each radio tag, data items representing the position and time at which the ID data item has been collected.

3. A data-collecting system according to claim 1, wherein the robot apparatus comprises route-data storage means for storing route data representing routes, and moves along the routes represented by the route data.

4. A data-collecting system according to claim 3, wherein the data-managing apparatus comprises:

plan-drawing means for drawing a plan of the specified space;

route-drawing means for drawing routes in the plan drawn by the plan-drawing means; and

route-data output means for outputting route data to the robot apparatus, said route data representing the routes drawn by the route-drawing means, and

the robot apparatus moves along the routes represented by the route data output by the route-data output means.

5. A data-collecting system according to claim 1, wherein the robot apparatus comprises:

tag-position storage means for storing the ID data of a specified radio tag and position data representing a position that the specified radio tag takes in the specified space; and

position-determining means for determining the position of the robot apparatus from the position data stored in the tag-position storage means, upon collecting the ID data of the specified radio tag.

6. A data-collecting system according to claim 1, further comprising data-reading unit comprising:

reading means for reading the data about the radio tags existing in a closed space; and

output means for outputting data read by the reading means, to the robot apparatus.

7. A data-collecting system according to claim 1, further comprising a unit which outputs electronically recorded, copyrighted data to the robot apparatus.

8. A data-collecting system according to claim 2, wherein the datainanaging apparatus comprises meta-data generating means for converting the property data to meta data.

9. A robot apparatus comprising:

map-data storage means for storing map data representing the geography of a specified space;

route-data storage means for storing route data representing routes existing in the specified space;

mobile means which moves in the specified space in accordance with the map data and the route data; and

ID-data reading means for reading tag ID data items from radio tags existing in the specified space, while being driven by the mobile means.

10. A robot apparatus according to claim 9, further comprising:

tag-position determining means for determining a position that each radio tag takes in the specified space, from the position of the robot apparatus; and

property-data generating means for generating property data by adding, to the ID data time stored in each radio tag, data items representing the position and time at which the ID data item has been acquired.

11. A robot apparatus according to claim 9, further comprising:

tag-position storage means for storing the ID data of a specified radio tag and position data representing a position that the specified radio tag takes in the specified space; and

position-determining means for determining the position of the robot apparatus from the position data stored in the tag-position storage means, upon collecting the ID data of the specified radio tag.
