The existing search engine cause heavy loads on web servers and networks, because they operate robots not considering the loads of many distributed diverse web servers and networks. As the information update period is 3～4 weeks, information is not updated at proper time. Although there is no contents to be updated on web servers, the robot collects and updates the contents of the web servers. This study proposes a intelligential search engine considering the load of web servers and networks, designs a real-time controlled search engine and intelligent robots, and implements them. The intelligent robot updates distributed information real-time. Robot control policies are also proposed, which can upgrade the overall performance of the system by monitoring the loads of web servers and networks.

This paper examine how acceptance of AI robots can be achieved according to occupational groups when the discourse on human labor and occupation changes due to the new industrial revolution is spreading steadily. Previous research on the acceptance of new technologies and products has predicted use behavior through subjective beliefs and values that do not change well over the short term. Therefore, this study compares the beliefs, values, and use intention of AI robots according to occupation. As a result, the subjective belief factor for AI robots was classified into belief in rationality(reason) and belief in benevolence(emotion). The value factors were divided into acceptance value(role performance, communication, social comparison) and avoidance value(risk, complexity). There was a significant difference in the effect of these on the use intention of AI robot by occupation and employment types. This result suggests that there are gaps in the occupation group at the rate of technology acceptance, as opposed to the existing prediction that AI robots will be rapidly expanded by professionals.

A theme park is not just a recreational space for leisure activities, but also a place of storytelling as collected around abstract boundaries called themes. These stories are 'a space that tells the meaning' that the visitor is looking for and the Robot Land space offers robots, humans, and nature. This study is a description of the design strategy and content of the work which was elected as a subject of the subsequent rank negotiation of the Masan Robot Land design contest for the selection of a private contractor. The focus of the plan is, first, the organizational power of each space and the delivery power of a theme for the history of revisits, which might be considered depending on whether or not the theme park has been successful in the visitor's mind. Second, it is to actively use the potential of Masan, which is not only the key hub of the mechanical industry but also has beautiful coastal resources. First, they created a space that can flexibly react depending on the user's desire and the change of form, minimizing environmental damage by using a linear metabolism that can provide an amalgam of the elemental characteristics of robots, humans, and nature as motifs. They introduced a planting plan for the admissions square, an existing forest, slope, vacation spot, the inside of a complex, and Eco Island, etc. by utilizing symbolic meaning and adjusting to the spatial characteristics of each space. In addition, they sought a detailed space by setting up zones tailored to the use and character of the subject area, having exhibitions and education about robots, vacation facilities for lodgers, various recreational and commercial facilities, and space for utopian gardens as themes. They planned Masan Robot Land to be a true cultural space that creates mental richness on the basis of not only the economical effects but also local emotion.

본 논문은 불확정 시스템의 견실한 이상검출기법의 적용을 위한 실시간 이상검출기법에 대하여 다루며 대상 시스템은 산업용보일러 시스템이다. 본 논문에서 기술된 이상검출기법은 Kwon (1994) 등에 의하여 이미 제시된바 있는 견실한 이상검출기법의 오프라인 배치 처리 알고리즘을 실시간 적용을 위해 확장된 것이며 모델링 오차에 의한 불확실성, 비선형 시스템을 특정 동작점에서 선형화 하는 과정에서 발생하는 선형화 오차, 잡음 등을 고려하였고, 보일러 시스템을 대상으로 한 모의 실험을 통해 본 알고리즘의 우수성을 보였다.

산업이 발달함에 따라 품질이 좋으면서 가격이 저렴한 철판에 대한 수요가 늘어나고 있다. 이러한 수요를 만족시키기 위해 제철소에서는 압연 시 발생하는 불량을 줄이기 위한 연구를 하고 있다. Flying Touch 기법은 열간 압연 시 발생하는 스크래치 불량을 줄이기 위한 방법이다. 본 논문에서는 Flying Touch 기법의 특징에 대하여 소개하고 Flying Touch 기법을 적용하여 실험할 수 있는 시뮬레이터의 설계와 제작에 대하여 간략하게 소개하였다. Flying Touch 기법은 아직 연구개발 단계의 방법이지만 제어 이론의 변화와 연구를 통해 더욱 개선될 수 있다.

MMS는 통신망으로 연결된 자동화기기와 컴퓨터 응용 프로그램간에 실시간 데이터와 감시제어정보를 교환하기 위한 국제표준의 메시지 교환 규약으로, MMS는 실행되는 응용기능의 종류나 기기의 개발자에 관계없이 표준적인 방법으로 정보를 교환하게 한다. MMS에서 제공되는 서비스들은 각종의 자동화기기와 응용 프로그램, 또한 여러 산업현장에서 필요로 하는 기능을 모두 만족하기에 충분하다. 그리고 MMS는 자동화된 생산공정을 구성하거나 사용하는데 필요한 경비를 줄여준다. MMS는 다양한 자동화 기기간의 통신을 하나의 통일된 규약과 방법론을 사용하여 이루고자 할 때 상호운용성(Interoperability), 독립성(Independence), 데이터접근(Data Access)성 등의 특징을 가장 잘 발휘할 수 있다.

This paper deal with the solution of kinematics and inverse kinematics of industrial FANUC robot by the bisection method with IBM PC 386. The inverse kinematics of FANUC robot cannot be solved by the algebraical method, because arm matrix T$_{6}$ is very complex and 6-joint angles are associated with the position and the approach of end-effector. Instead we found other 5-joint angle by an algebraical method after finding .theta.$_{4}$ value by a bisection method.d.

This paper deals with the robust controller design of robotic manipulator to track a desired trajectory in spite of the presence of unmodelled dynamics in cause of nonlinearity and parameter uncertainty. The approach followed in this paper is based on model reference adaptive control technique and convergence on hyperstability theory but it does away with assumption that process is characterized by a linear model remaining time invariant during adaptation process. A computer simulation has been performed to demonstrate the performance of the designed control system in task coordinates for stanford manipulator with payload and disturbances.

The multi-task operating system called HRMTOS (HUNDAI Robot Multi-task Operating System) was developed for concurrent execution. HRMTOS consists of condition interpreter, queue constructor, task scheduler. Condition interpreter checks the status and condition of request, queue constructor makes queue according to the checked result by condition interpreter, and task scheduler finds the task that will be urgently executed by priority of queue after pending the current excuting task. HRMTOS could execute teaching, playback, monitoring function of multi-robot and could be used more effectively than other robot controllers.
