This paper presents the development of a Parallel-Typed CNC Machining Tool. It is specially designed to machine a complex shaped workpiece by controlling the orientation of the tool. The inverse/direct kinematics of a parallel mechanism is derived and implemented in a PC based controller. With graphics icons, the GUI (Graphic User Interface) program is developed for the CNC programing. The calibration is accomplished by geometric constraint motion, which is a parallel motion of the platform with respect to a table. The calibration result is introduced and the future study is proposed.

실시간 운영체제 GUI 에서 가장 중점적인 것은 임베디드 시스템상에서 중요한 자원 중 하나인 메모리의 효율적인 관리이다. 특히 파일시스템이 없는 임베디드 시스템의 경우 GUI 를 사용하게 되면 폰트 이미지(Font Image)와 그림파일 등이 메모리상에 존재하여야 하기 때문에 메모리를 많이 차지하게 된다. 본 논문에서는 실시간 운영체제 $UbiFOS^{TM}$에서 파일시스템 모듈을 제거하고 GUI 를 설계 및 구현하였고 특히 폰트 이미지와 그림파일을 처리하는 방법과 폰트 이미지를 위한 메모리를 절약할 수 있는 메커니즘을 제안하였다.

In this paper, we introduce a case study of developing a miniature humanoid robot that has 16 degrees of freedom and is able to perform statically stable walking. The developed humanoid robot is 37cm tall and weighs 1,200g. RC servo motors are used as actuators. The robot can walk forward and turn to any direction on even surface. It equipped with a small digital camera, so it can transmit vision data to a remote host computer via wireless modem. The robot can be operated in two modes; One is a remote-controlled mode, in which the robot behaves according to the command given by a human operator through the user-interface program running on a remote host computer, the other is a stand-alone mode, in which the robot behaves autonomously according to the pre-programmed strategy. The user-interface program also contains a robot graphic simulator that is used to produce and verify the robot's gait motion. In our walking algorithm, the ankle joint is mainly used lot balancing the robot. The experimental results shows that the developed robot can perform statically stable walking on even surface.

We propose a new technique to design an unmaned integrating control system based-on Windows XP version off-Line Programming System which can simulate a dynamic model of robot manipulator in three dimensions graphics space in this paper. The robot with 4 and 6 axes modeled SM5 and AM1 respectively were adopted as an objective model. Forward kinematics, inverse kinematics and robot dynamics modeling were included in the developed off-line program. The interface between users and the off$.$line programming system in the Windows XP's graphic user interface environment was also studied. The developing language is Microsoft Visual C++. Graphic libraries, OpenGL, by silicon Graphics, Inc. were utilized for three dimensions graphics.

There are many development methods to implement wireless internet service. These methods are WAP(Wireless Application Protocol) based services and Java based service WAP based service has been proposed to support limited convenience for user But Java based service can support many convenience and GUI(Graphic User Interface) and easy to use to access for user. This paper will be propose a WAP based application development method and Java based application development method. As an illustrative experiment, WAP based service and Java based service are used to show performance for each systems.

The steam turbine rotor blade is designed using the Turbine Rotor Design Package developed by the authors. It can quickly accomplish blade shape design in the power plant industry. The quasi-3d code is employed for analysis of passage flow in the blade sections. Iterative change of each blade shape is made by moving position of control points in the Bezier curve under GUI(graphic user interface) environment. The full 3-D blade shape is obtained by stacking of the section blades.

In this paper, we implement the ad ballon control system in which a built camera monitors using bluetooth wireless communication with ISM(Industrial. Scientific and Medical) band. In the proposed system. the driving time of ad ballon is increased by adopting the mercury battery and light weight. An ad ballon with camera is easily controlled by Graphic User Interface using Linux based embedded system.

This paper develops the dynamic equivalents program combined with graphic user interface(GUI), to solve the stability of large power system. The p개posed method is coherency-based dynamic equivalents for transient stability studies. The program also provides with pull-down menu and Hangout help information for users. The developed dynamic equivalents program is suitable for the transient stability studies of a large power system with lots of data. The dynamic equivalents demonstrated over the New England system with 39 buses and 10 generators.
