20090063388 | LEARNING APPARATUS AND METHOD OF INTELLIGENT SYSTEM - A learning apparatus and method of an intelligent system according to the present invention relates to learning of an intelligent system that automatically controls a system on the basis of information about events generated in an external environment or services input by a user. In the learning, it is determined whether rules extracted from event data or service data are the same as rules already stored. Then, if it is determined that the rules are new rules, queries about the confidence of new rules are generated and provided to a user. The rules are updated on the basis of user's answers. Accordingly, it is possible to accurately grasp users' patterns by using very small amount of observation data as compared to an existing method, and to more easily sense variable patterns. Therefore, it is possible to obtain a more intelligent learning in the intelligent system. | 03-05-2009 |

20100145514 | APPARATUS AND METHOD FOR CONTROLLING MULTI-ROBOT LINKED IN VIRTUAL SPACE - The present invention relates to an apparatus and method for controlling a multi-robot linked in virtual space, and when an event is generated in accordance with information change in virtual space including the web as well as the environmental change around a robot, the present invention controls individual behavior or collective behavior or corresponding robots by transmitting behavior data corresponding to the generated event to a plurality of robots. According to the present invention, by making a robot perform specific behavior in response to not only changes in the real environment, but information changes in the web, it is possible to arouse the user's interest or the developer's originality while removing due to complicity of the real environment, which is a problem limiting application of the robot, or dynamic response. | 06-10-2010 |
20100168914 | DIAGNOSIS AND MANAGEMENT SERVER FOR MULTI-KINDS ROBOTS - Provided proposes a structure of a robot management server and an internal structure of a robot that can interwork with an external server providing functions such as voice recognition, voice synthesis, image recognition, speaker recognition, gesture recognition, etc., and provide the corresponding functions as basic functions of the robot. Through the structure, the same interface, which accesses the internal structure of the robot, can be provided and the robot developer can develop applications handling multi-kinds robots and applications without being limited by the basic functions of the robot, by using the interface. In addition, malfunction and failure, which can occur during the operation of the robot, are checked by diagnosing, such that applications capable of appropriately processing the malfunction and failure can be developed. | 07-01-2010 |
