Abstract

Provided is a robot control system and a method thereof. The robot control system includes: a mobile robot comprising at least one camera; and a controller, wherein the controller is configured to transmit, to the mobile robot, a signal for adjusting a resolution of a next image to be transmitted from the at least one camera to the controller, based on a data transmission rate of a current image captured by the at least one camera and output to the controller, and wherein the mobile robot is configured to adjust the resolution of the next image, based on the signal for adjusting the resolution of the next image.

Claims

1. A robot control system comprising:

a mobile robot comprising at least one camera; and

a controller,

wherein the controller is configured to transmit, to the mobile robot, a signal for adjusting a resolution of a next image to be captured and transmitted by the at least one camera to the controller, based on a data transmission rate of at least one channel for the at least one camera at which a current image captured by the at least one camera is transmitted to the controller,

wherein the mobile robot is configured to adjust the resolution of the next image, based on the signal for adjusting the resolution of the next image,

wherein the at least one camera comprises a plurality of cameras configured to capture a plurality of current images and output the captured current images to the controller through a plurality of channels, respectively,

wherein each of the current images has an importance degree for each of the channels, and

wherein the resolution of the next image is adjusted based on the importance degree for each of the channels.

2. The robot control system of claim 1, wherein the resolution of the next image for each of the channels is adjusted to be inversely proportional to a data transmission rate of each of the channels.

3. The robot control system of claim 2, wherein the resolution of the next image for each of the channels is adjusted to be proportional to the importance degree.

4. A mobile device control system comprising:

a mobile device comprising at least one camera; and

a controller,

wherein the controller is configured to transmit, to the mobile device, a signal for adjusting a resolution of a next image to be captured and transmitted by the at least one camera to the controller, based on a data transmission rate of at least one channel for the at least one camera at which a current image captured by the at least one camera is transmitted to the controller,

wherein the mobile device is configured to adjust the resolution of the next image, based on the signal for adjusting the resolution of the next image,

wherein the at least one camera comprises a plurality of cameras configured to capture a plurality of current images and output the captured current images to the controller through a plurality of channels, respectively,

wherein each of the current images has an importance degree for each of the channels, and

wherein the resolution of the next image is adjusted based on the importance degree for each of the channels.

5. The mobile device control system of claim 4, wherein the resolution of the next image for each of the channels is adjusted to be inversely proportional to a data transmission rate of each of the channels.

6. The mobile device control system of claim 5, wherein the resolution of the next image for each of the channels is adjusted to be proportional to the importance degree.

7. A controlling apparatus comprising:

a communication interface configured to receive data of at least one image captured by at least one camera, respectively;

a controller configured to transmit, to the at least one camera, at least one signal for adjusting a resolution of a next image to be transmitted from each of the at least one camera to the controller, based on a data transmission rate of at least one channel for the at least one camera at which a current image captured by each of the at least one camera is transmitted to the controller,

wherein the at least one camera comprises a plurality of cameras configured to capture a plurality of current images and output the captured current images to the controller through a plurality of channels, respectively,

wherein each of the current images has an importance degree for each of the plurality of channels, and

wherein the resolution of the next image is adjusted based on the importance degree for each of the channels.

8. The controlling apparatus of claim 7, wherein the resolution of the next image for each of the channels is adjusted to be inversely proportional to a data transmission rate of each of the channels.

9. The controlling apparatus of claim 8, wherein the resolution of the next image for each of the channels is adjusted to be proportional to the importance degree.
