우리 주변에서 인터넷에 접근할 수 있는 기반시설이 풍부하게 제공 되어 최근 출시되는 많은 가전제품과 전기전자 제품들은 인터넷에 접속하여 웹브라우저나 휴대폰을 이용하여 원격으로 감시하고 제어할 수 있다. 그러나 기존의 제품들은 대부분 인터넷 인터페이스가 없기 때문에 네트워크에 접속할 수 없어 불편함이 많았다. 따라서 본문에서는 주변의 가전제품 및 전기용품들을 인터넷 환경에서 감시하고 제어할 수 있는 인터넷 전원 콘센트를 위한 임베디드 WEB 제어환경을 설계하고 구현하였다. 본 논문에서 사용한 인터넷 전원 콘센트 제어기는 위즈넷사에서 개발한 하드웨어 TCP/IP 프로세서인 W5300을 사용하여 AVR 마이크로프로세서로 운영 가능한 인터넷 인터페이스를 설계하고 임베디드 WEB 서버를 구현하였다. 하드웨어 TCP/IP 프로세서를 사용하여 이더넷 인터페이스를 구현함으로서 소형의 8비트 마이크로프로세서로 완전한 TCP/IP 스택의 구현이 가능하여 개발제품의 가격 경쟁력과 소형화에 기여할 수 있다.

This paper is concerned with the development of remote engineering laboratory using the internet. Recently, various virtual laboratories are introduced using the multimedia technologies but the internet laboratory using the real hardware system is not present. In this study, we developed the remote engineering laboratory by combining the GPIB program which controls the hardwares with the web programming which controls the internet. The function generator, LCR meter, and oscilloscope were considered as the measurement devices. The client program includes the user-interface which carry out experiment remotely. Several electrical experiments were set up to verify the experimental process. It has been found that the remote engineering experiments are feasible and valid. The methodologies will be discussed in detail.

The technological advances such as communication, sensor, and artificial intelligence lead smart factory construction. Smart factory aims at efficient process control by utilizing data from the existing automation process and intelligence technology such as machine learning. As a result of constructing smart factory, productivity increases, but costs increase. Therefore, small companies try to make a step-by-step transition from existing process to smart factory. In this paper, we have proposed a remote control system that support data collection, monitoring, and control for manufacturing equipment to support the construction of CNC cutting machine based small-scale smart factory. We have proposed the structure and design of the proposed system and efficient sensing data transmission scheme. To check the feasibility, the system was implemented for CNC cutting machine and functionality verification was performed. For performance evaluation, the web page access time was measured. The results means that the implemented system is available level.

In recent years, many home machines have been developed in order to design and control comfortable interior inside houses. For such task, important factors are temperature, natural and interior lights, and space and control of relative factors each other. This paper presents novel sensor module inside houses, which is designed based on these factors through the PMV (Predicted Mean Vote) standard using information about home state. Moreover, LonWorks based power line communication technique is utilized for control interior lights and air-conditioners by means of wireless remote controllers. This mechanism is systemically operated via intelligent control framework.

In this paper, the two-wheels robot using a predictive controller to maintain the balance of the posture control in real time have been examined. A reaction wheel pendulum control method is adopted to maintain the balance while the bicycle robot is driving. The objective of this research was to design and implement a self-balancing algorithm using the dsPIC30F4013 embedded processor. To calculate the attitude in ARS using 2 axis gyro(roll, pitch) and 3 axis accelerometers (x, y, z). In this study, the disturbance of the posture for the asymmetrical propose to overcome the predictive controller which was a problem in the control of a remote system by introducing the two wheels of the robot controller and the linear prediction of the system controller combines the simulation was performed. Also, the robust characteristic for realizing the goal of designing a loop filter too robust controller is designed so that satisfactory stability of the control system to improve stability of the system to minimize degradation of performance was confirmed.

We propose a remote controller for a SCARA typed direct drive manipulator with two degrees-of-freedom(DOF). A remote controller system for SCARA robot of DDA is designed using a 2 DSP (TMS320c31) board and Winsock(Internet program class library supplied by Microsoft). The design objective of the system is to implement real time dynamic control algorithms which have been tested only by simulations so far and remote control regardless of the distance between user and robot. Because this system runs on Win95, we developed a VxD program to communicate with DSP controller.

Teleoperation is the extension of a person's sensing and manipulation capability to a remote location. Teleoperators generally can be modeled as linear transfer function indecently including modeling uncertainty. Modeling uncertainties can make the system unstable and its performance poor. Thus I'm studying about a design framework for a bilateral controller of teleoperator systems with modeling uncertainties. In this paper, a method based on the H$_{\infty}$-optimal control and .mu.-synthesis frameworks are introduced to design a controller for the teleoperator that achieves stability and performance in the presence of the modeling uncertainties..ties.inties.

The animatronics technique could be very important fact of technique not only to achieve full completion of visible image but also to offer lots of chances to express images by merging CG, special effects and special devices. In this thesis, we design and implement the Zigbee-based wireless transceiver and communication program to control animal animatronics such as a dog and bear. The wireless control utilizing the Zigbee protocol is that electrically consumption is more small than the Bluetooth and reliability of data transmission is better. The implemented control systems and program have the normal and replay function for control of animal models. This functions and operability are tested by a designed animatronics prototype under the wireless environment.
