20090018698 | ROBOT SYSTEM BASED ON NETWORK AND EXECUTION METHOD OF THAT SYSTEM - The present invention relates to a network-based robot system and an executing method thereof. According to an exemplary embodiment of the present invention, predefine environment information is expressed in a universal data model (UDM) described by a linkage that shows a relationship among nodes, each node being an object of a virtual space abstracted by a real physical space. The universal data model is updated based on the context information, event occurrence information is transmitted to a task engine when the context information data value is changed, and the task engine executes a corresponding task through reasoning and invokes an external service. The robot can better recognize the context information by utilizing the external sensing function and external processing function. In addition, the robot system can provide an active service by reasoning the recognized context information and obtaining high-level information. | 01-15-2009 |
