A tole-robot system for remote home-management has been developed. The tele-robot system is composed of a mobile robot system, server-computers and client-computers. The robot system is equipped with wireless camera and wireless controller so that the robot system captures the image remotely User makes the robot control command referring to the image feedback through internet. With such tole-robot system, the user can monitor and watch the inside of home by remotely maneuvering the mobile robot. The user can also save the received image of suspected scene on the client computer. Utilizing such function of tele-robot system, remote home-management and possible crime avoidance could be achieved.

급속한 인터넷 사이트와 이용자들의 증가로 인해 이용자들의 요구에 부응하는 정보를 위한 검색 엔지들의 개발이 가속화되고 있다. 이로 인해 많은 검색엔진들의 문서 수집 활동으로 인한 대상 호스트들에 대한 부하가 초래되었고, 방대한 양의 새로운 정보가 추가되어 가는 상황에서 모든 정보의 주기적인 갱신이 필요하게 되었다. 이러한 시대적인 상황과 검색시스템의 기본요건이 빠른 속도와 정확한 정보 수집을 이루기 위하여 방대한 호스트내의 문서를 수집할 수 있는 기술의 필요성이 높아졌으며, 이용자들의 다양한 요구와 WWW(World Wide Web)간의 상호 유기적인 작용을 위한 검색 엔진의 역할이 더욱 커지고 있다. 본 연구에서는 기존에 제시되었던 로봇 에이전트 시스템에 대한 비교 분석 후 이들을 보완하여 대상 서버에 대한 부하량 측정치와 로봇이 수집 활동 시에 체험한 부하량을 함께 고려하여 문서수집이 빠른 시간 내에 이루어지며 대상 서버에 과도한 부하를 주지 않는 로봇 에이전트와 원격 관리 시스템을 설계 및 구현한다.

Robot control involves advance programming, scientific and high technology. The systematic and methodological aspects of robot controls often results in having superficial control design problems that can negatively affect the robot application, usability and appeal. User friendly interface of robot control is extremely advantageous and more attractive. To illustrate, the application of medical robot is usually handled by clients who have little background in advance programming language. Thus, it would be difficult if the client needs to use programming language to control the robot. It would justify better if the robot control is presented in a meaningful interface to the client. This way the robot application would be more natural and user friendly. This paper describes the method of developing the user interface for web based communication to control an internet robot named Tarou. The web based communication tasks involves three levels. The first one accommodates on the client sending commands to robot through the internet. The next communication level relates to the robot receiving the commands sent by the client. The final communication level generates on sending feedback on status of commands by the robot to the client. The methodology used here can be elaborated in four hierarchical steps; identify user needs and robot tasks, identify the enhancing tag reference used by the server, induce the tag into HTML, present the HTML in attractive user interface as the client control panel.

This paper proposes a common platform for an internet-based mobile robot and its operator terminal. The common platform can reduce the cost and time to develop an internet-based robot and its operator terminal. The robot performs the role of a server and its terminal a client. One operator can use this terminal to make a command and this command can be sent to the robot through a wireless network. According to given commands, the robot moves a point and sends an image by using a camera or desired information by using other sensors. The information sent from the robot can help an operator to control the robot. The mobile robot consists of two modules, main module and motion module. Main module can exchange information with the operator terminal, process information, and send a command to motion module. Each application program for one internet-based mobile robot and its operator terminal will be developed to show that the same platform can be used for them. Also, it will be shown that the robot can be controlled easily by using its operator terminal.

In this paper, we develope a type of humanoid robot which can express its emotion against human actions. To interact with human, the developed robot has several abilities to express its emotion, which are verbal communication with human through voice/image recognition, motion tracking, and facial expression using fourteen Servo Motors. The proposed humanoid robot system consists of a control board designed with AVR90S8535 to control servor motors, a framework equipped with fourteen server motors and two CCD cameras, a personal computer to monitor its operations. The results of this research illustrate that our intelligent emotional humanoid robot is very intuitive and friendly so human can interact with the robot very easily.

모바일 기기의 발달과 함께 스마트한 기능을 갖는 로봇은 우리 생활에 안전과 편리함을 제공하고 있다. 본 연구에서는 원격 제어가 가능한 모바일 기반 다중 로봇카 시스템을 연구한다. 아두이노를 탑재한 로봇카는 서버에서 제어가 가능하지만, 제어자의 원격 제어가 필요함에 따라 모바일 기기로도 제어가 가능하도록 하였다. 또한 여러 대의 로봇카와 여러 대의 모바일 기기를 이용하여 제어하고자 하는 로봇카를 선택할 수 있어 동시에 여러 로봇카의 제어가 가능하도록 하는 특징을 가지고 있다.

Network technology has been developed rapidly for digital service in these days. ZigBee, one of the IEEE 802.15.4 protocols, supporting local communication has become the core technology in the wireless network area. In this paper we designed an integrated fire monitoring system using a mobile robot and the ZigBee sensor nodes which are deployed to monitor fires. When a fire breaks out, the image information of the scene of a fire is transmitted by an autonomous mobile robot and we also monitor the current position of the robot. Furthermore, the data around the place where the fire breaks out and the positions of the sensor nodes can be transmitted to a server via the multi-hop communication in the real time.

Nowadays there are lots of researches on robot systems working on danger environments and control led remotely. In this paper, we describe a virtual robot interface system based on Internet In the system, a client can order scanning for range finding, then server detects a 3D profile data from the objects by using robot controlling and a range finder automatically. If one clicks the original position of object and destination on virtual space, the robot moves the object to the new position in real space. The proposed interface system supports advanced virtual 3D interface and makes it possible one to manage the objects remotely more conveniently.

In this paper, we have designed a Home Networking System using an embedded linux board. The system based on the World-Wide-Web is composed of three parts - a Server, a Client and a Simulator. The Home Networking Server is built in an embedded board using an embedded linux kernel. A web-server and Home Networking Server Seryice Demon programming with a Jaya-Language is included in the board. Clients can connect to the server board using a web-browser in the desktop computer, PDA or any other machines which include a web-browser. For this purpose, we made the client program using a Java-Applet. So, the clients who connect to the server for the control of the applications, download the class-file and execute the client-program in the web-browser. So, the clients don't need any other programs to control the applications from a remote place. The size of server board is very small (86.3$\times$74mm), which makes it very useful not only for the Home-Networking-System but also in many other fields, e.g., embedded robot control system, etc. Using an embedded board instead of a desktop computer is good for a simple network environment and it occupies only a small space to make the system.

로봇의 실외 주행의 경우 실내 주행과 달리 실외 환경 전체에 대한 지도를 미리 작성할 수 없어 대부분 GPS를 이용하고 있으며 지도에 기반한 연구는 거의 없는 상황이다. 본 논문에서는 경사 구간이 없는 2차원 평면의 실외환경에서 정밀 GPS를 사용하여 GPS 데이터를 MCL 알고리즘에 적용하여 실외 로봇 위치 추정을 구현하고, 이를 적용하여 간단한 임무 시나리오를 수행하였다. 그리고 미들웨어 기반의 OpenRTM을 적용하여 관리자가 서버를 통해 원격으로 로봇을 제어하거나 상황을 관제할 수 있도록 하였다.
