The purpose of the present. paper are not to develope machine tools of new concepts and advanced mechanisms but to introduce and apply new methods and concepts in the design procedure by using and changing the previously existing technologies. In this paper 3D modeller was proposed for designing machine tools and the design automation software(DesignMecha 2000) was used. 3D modeller enabled more fast design and the better manufacturability checking than 2D one so that design error was dramatically reduced. As designer may easily understand the real shape of a part and assembly object, it's easy to draw the drawings not only in a conceptual design but also in a detailed design. Also, design automation software enabled designer to consider the real important design parameters by reducing time to spend in estimating and calculating the strength of the model by the computer aided automatic calculation instead of a tedious and complex: calculation by manual method and help him to easily make the decision for selecting the stocks and design the structure of part or unit of machine tools.

This paper presents an strategy algorithm of a soccer robot. We simply classified strategy of soccer robot as attack and defense. We use DC-motor in our Soccer Robot. We use the vision system made by MIRO team of Kaist and Soty team for image processing. Host computer is made by Pentium III. The RF module is used for the communication between each robot and the host computer. Fuzzy logic is applied to the path planning of our robot. We improve strategy algorithm of soccer robot. Here we explain improvement of strategy algorithm and fault of the our soccer robot system.

This study deals with CARS (Computer Aided ROMUM System) which is a computer version of ROMUM (RObot Modularization of the Unit Motion). ROMUM was a method developed by the concept of modularization of the unit motion of robots. Because CARS is a computer assisted method of menu-driven type for human interface, this method can be easily applied for analyzing the work motion and measuring the execution time of robots. Therefore, it will be helpful for reducing the analysis effort and time of robot work.

Recently, the ultra-precision stage is widely used in the fields of the nano-technology, specially in AFMs(Atomic Force Microscope) and STMs(Scanning Tunneling Microscope). In this paper, the ultra-precision stage which consists of flexure hinges, piezoelectric actuator, and ultra-precision linear encoder, is designed and developed. The guide mechanism which consisted of flexure hinges is analyzed by Finite Element Method. And we derived the transfer function of the system in 1st order system from step responses according to the magnitude. We performed simulation for the model to tune the control gain and applied the gains to the developed system. Experimental results found that the stage can be controlled in 5 nm resolution by PID controller.

The hydraulic excavator has been a popular research object for automation because of its multi-workings and economic efficiency. When it works crane tasks, most of disasters happen. The stability of the excavator having crane function has a close relation with excavator's posture, motion and load. In this paper, the stability of tipping-over has been analysed using Zero Moment Point(ZMP),
