Abstract

In the present invention, a common robot interface framework (CRIF) is defined. CRIF is a standard of a common interface using a kind of imaginary robot for the purpose of the abstraction of hardwares in order to decrease the dependency of an application on hardware platforms and to increase a transplantation and a CRIF-framework for supporting the interface in a client-server environment.

8. The method of claim 4, wherein the step of transferring the image data obtained by the robot abstraction class from the outside to the robot application stores the image data obtained from the outside in a double buffer provided with two buffers and transfers the same.

9.

11. The method of claim 4, wherein the step for obtaining an external image data by the robot abstraction class is performed at the same time when data is stored in a double buffer in the step for transferring the image data obtained by the robot abstraction class to the robot application.

12. The method of claim 4, wherein the step for transferring an image data obtained by the robot abstraction class from the outside to the robot application includes a step for transferring the obtained image data to the robot application in case that a request command to transfer an image is delivered from the robot application.

13. The method of claim 4, wherein an image shot by one lens of the stereo camera is represented as a colored image and an image shot by the other lens of the stereo camera is represented as a black and white image.

14. A method for transmitting and receiving a camera image signal on a robot common framework, comprising:

requesting a robot application to transfer an image data to a robot abstraction class;
