RC(Remote Control) is a technology that can efficiently control and transfer a variety of user commands to CEs. However, the existing RCs have been required various additional features such as communication between CEs, extension of communication range, low power-consumption and bi-directional communication according to the advent of new types of CE devices and its enhanced performance. Even though RC controller has many customers' requests, it is not a simple solution because most legacies work on IR-based RC. In this paper, we propose RF4CE-based Universal Remote Control Framework using Smartphone in order to solve the many constraints of IR legacies. The proposed R-URC system is designed by RF4CE platform which is a kind of de-facto standard for CE remote control communication. From the verification scenarios using various CEs and smart phone, we can see that the proposed R-URC shows the good practical usage in terms of contents sharing and smart CE control.

This paper is about a system development which control and monitor a PLC of the remote-distance through the Internet using the web-browser. In general, the PLC uses its own communication protocol of PLC Manufacture. It is actually impossible to be used through the Internet, because the PLC communication protocol is basically developed to be suitable for short-distance. Therefore, what we need is a transformation system which can convert the PLC communication protocol into the form which can connect to the Internet. In that sense, this paper is that about remote-control method through the WWW ( World Wide Web ). This system have three characteristics. First, it is possible to connect the Internet directly irrespective of CPU, Operating system and browser. Second, it is easy for user to access and treat. Third, it needs only HTML to operate without java or plug-in expansion. In this paper, we will introduce the monitoring and control system of PLC on the Linux with the Apache web-server.

Mobile devices such as cellular phones and PDA become a part of our life by extreme improvement of Wireless internet and arriving the age of Ubiquitous. Especially it makes increasing rapidly the expectations about a field of remote control that is great advantage of Mobile devices. Existing computer remote control systems are hard to meet user's appropriate manage when error happened because Clients could not recognize the state of several remote controlled computers which connected to web server. This paper Implementation remote computer control system that immediately after errors happen by send error massages in the from of a SMS to client by set the clients with cellular phone that most generally used Mobile devices.

In this paper, fault tolerant mechanisms are presented for a servo manipulator system designed to operate in a hot cell. A hot cell is a sealed and shielded room to handle radioactive materials, and it is dangerous for people to work in the hot cell. So, remote operations are necessary to handle radioactive materials in the hot cell. KAERI has developed a servo manipulator system to perform such remote operations. However, since electric components such as servo motors are weak to radiations, fault tolerant mechanisms have to be considered. For fault tolerance of the servo manipulator system, hardware and software redundancy have been considered. In case of hardware, radioactive resistant electric components such as cables and connectors have been adopted and motors driving a transport have been duplicated. In case of software, a reconfiguration algorithm accommodating one motor's failure has been developed. The algorithm uses redundant axis to recover the end effector's motion in spite of one motor's failure.

With a remote operated manipulator system, the situation at a remote site can be rendered through remote visualized image to the operator. Then the operator can quickly realize situations and control the slave manipulator by operating a master input device based on the information of the virtual image. In this study, the remote operator visual support system (ROVSS) was developed for viewing support of a remote operator to perform the remote task effectively. A visual support model based on virtual environment was also inserted and used to fulfill the need of this study. The framework for the system was created by Windows API based on PC and the library of 3D graphic simulation tool such as ENVISION. To realize this system, an operation test environment for a limited operating site was constructed by using experimental robot operation. A 3D virtual environment was designed to provide accurate information about the rotation of robot manipulator, the location and distance of operation tool through the real time synchronization. In order to show the efficiency of the visual support, we conducted the experiments by four methods such as the direct view, the camera view, the virtual view and camera view plus virtual view. The experimental results show that the method of camera view plus virtual view has about 30% more efficiency than the method of camera view.

Manipulating a car navigation system while driving can lead to car accident due to loss of concentration. This will be more serious for elders or beginner drivers. Recently, a new Road Traffic Law in Korea prohibits drivers from watching or operating any video displaying devices. So the car navigation system came hard to use. In order to solve the issue we design and implement a novel system where a remote person can control the car navigation system on behalf of the driver. In the proposed system, we suggest to utilize the driver's smartphone for allowing sharing the Internet connection of the phone with the navigation system. The required smartphone application and the server will also be designed and implemented.

We developed a remote control system for the 16" reflecting telescope at KNUO (Kongiu National University Observatory). This system is a close loop system. The electronic control part used TCS-196 of the Korea Astronomy Observatory, the mechanical part was developed directly in this research. The pointing accuracy of this system was ${\pm}$50" in the hour angle direction, ${\pm}$40" in the declination direction after mount modeling. The tracking accuracy was about 1"/min. This pilot test result means that this system is suitable for research or education of astronomical fields.

Automated manufacturing systems are applied to shop floors as a tool for the increase of productivity and quality and the decrease of manufacturing lead times and industry accidents. One of the most important issue of the present day is the application of Internet. The development of Internet technologies makes manufacturing enterprises break spacial barriers between users and shop floors, and collect various field data in remote sites. In this research, an Internet-based remote control system for a small-sized automated storage and retrieval system is developed for the purpose of real-time monitoring and control of automatic production equipment. The developed system has a client-server architecture and transmits real-time images of the automated storage and retrieval system to a client by ar CCD camera connected to a server. Based on the transmitted images, the client sends commands to PLC of the server, and part storage and retrieval tasks are executed.
