Abstract

An unmanned apparatus obtains position information and communication quality and traffic information while traveling, synchronizes the position information with the communication quality and traffic information, maps the communication quality and traffic information for each poison, synchronized with the position information, to geographical information, displays the geographical information on an electronic map, and sets a traveling path using the electronic map.

Claims

1. An unmanned apparatus for performing a task while traveling, the unmanned apparatus comprising:

an information providing apparatus for obtaining communication quality and traffic information while transmitting and receiving a control signal and a data signal, obtaining a position of the unmanned apparatus according to a movement, mapping the communication quality and traffic information for each position to geographical information, and displaying the geographical information on an electronic map; and

a traveling apparatus for setting a traveling path using the electronic map on which the communication quality and traffic information for each position is displayed.

2. The unmanned apparatus of claim 1, wherein the traveling apparatus sets the traveling path based on traveling information and changes the traveling path based on the communication quality and traffic information for each position.

3. The unmanned apparatus of claim 2, wherein the traveling apparatus excludes a position, having a communication state less than a predetermined reference value, from the traveling path based on the communication quality and traffic information.

4. The unmanned apparatus of claim 1, wherein the information providing apparatus further comprises a position detection unit for obtaining the position of the unmanned apparatus, and

the position detection unit obtains the position from satellite signals.

5. The unmanned apparatus of claim 4, wherein the position detection unit obtains the position of the unmanned apparatus using internal sensors when a strength of the satellite signal is a predetermined threshold value or less.

6. The unmanned apparatus of claim 1, further comprising a traveling database, wherein the traveling apparatus stores the traveling path in the traveling database after traveling.

7. A method of setting a traveling path when driving a moving unmanned apparatus, comprising the steps of:

obtaining communication quality and traffic information about a communication signal according to a relevant communication method while transmitting and receiving a control signal and a data signal;

obtaining a position of the unmanned apparatus according to a movement;

synchronizing the communication quality and traffic information with each position;

mapping the communication quality and traffic information for each position to geographical information and displaying the geographical information on an electronic map; and

setting the traveling path using the electronic map on which the communication quality and traffic information for each position is displayed.

8. The method of claim 7, wherein the step of obtaining the position of the unmanned apparatus according to the movement comprises the steps of:

receiving satellite signals;

when an strength of the satellite signal is greater than a threshold value, calculating the position from the satellite signal; and

when the strength of the satellite signal is the threshold value or less, calculating the position using internal sensors.

9. The method of claim 7, wherein the step of setting the traveling path comprises the steps of:

setting the traveling path based on past traveling information; and

changing the traveling path based on the communication quality and traffic information for each position.

10. The method of claim 9, wherein the step of changing the traveling path comprises the step of excluding a position, having a communication state less than a predetermined reference value, from the traveling path based on the communication quality and traffic information.

11. The method of claim 9, wherein the step of changing the traveling path comprises the step of returning to a position right before a position, having a communication state less than a predetermined reference value, based on the communication quality and traffic information if a traveling path to be changed does not exist in the position having the communication state less than the predetermined reference value.

12. The method of claim 7, further comprising the step of photographing an image while moving, wherein the step of synchronizing the communication quality and traffic information with each position comprises the step of synchronizing the image photographed at the position with the communication quality and traffic information.
