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.

Driving simulators provide engineers with a power tool in the development and modification stages of vehicle models. One of the most important factors to realistic simulations is the fidelity obtained by a motion bed and a real-time visual image generation algorithm. Virtual reality technology has been widely used to enhance the fidelity of vehicle simulators. This paper develops the virtual environment for such visual system as head-mounted display for a vehicle driving simulator. Virtual vehicle and environment models are constructed using the object-oriented analysis and design approach. Based on the object model, a three-dimensional graphic model is completed with CAD tools such as Rhino and Pro/ENGINEER. For real-time image generation, the optimized IRIS Performer 3D graphics library is embedded with the multi-thread methodology. The developed software for a virtual driving simulator offers an effective interface to virtual reality devices.

In the field of video design, motion graphics tends to be realized to deliver a certain message properly incorporating basic motion graphics components such as space, form of expression, and time, and has continued to be used as a powerful communication tool. Many cases proved that title sequences were produced as a result of combination of a variety of quick images and effects with appropriately chosen sounds to meet the demands of audience. This study indicated that motion graphics began to be widely used as a more powerful video communication tool for title sequences and also applied for M-NET, DMB, CABLE TV, IPTV, and others.

Nowadays, 3-D(Three-dimensions) is used in various field such as Games, Movies, Animations etc. Especially the Role of 3-D computer graphic is being generalized by turnover of Screen from '2-dimensional' to '3-dimensional'. There are not enough data about 'Motion Capture' even though it plays main function in 3-dimensional movement. 'Motion Capture' could be also unfamiliar for people. And as a matter of fact, the use of this equipment is limited due to its high cost. Therefore, I studied the outline of Digital Motion Capture system and its application to 3-D game Character Animation. And I checked the movement of 3-D Character after transplanting the Motion Data to the 3-D Character. I acquired Motion Data by Optical Motion Capture Equipment which we possess and transplanted it into the 3-D Character then Implemented it as walking, running and hitting which are the basic motions of Expression.

The automatic control and motion control technology including the sensor network technology are important in the ubiquitous environment to make human life easy. In the industrial site and living environment, the demand for the motion control technology and position control technology which are faster and more precise is increasing. Especially, demand for the PC based motion control system is mounting in order to keep up with the improved GUI environment and ever-changing industrial site. This research is focused to develop the Highly Efficient 2-axis Step Motion Control System which can be variously applied in the industrial site on the basis of the LabVIEW - graphic code programming language - with user interface, using the NI PXI-7352 controller and the NI step motor in which it provides the high reliability and the precise motion control.

In this paper, the performance analysis of the vehicle with the Ravigneaux type automatic transmission has been carried out using information of engine and drivetrain. It is necessary to understand the overall system including engine, torque converter, clutch, planetary gears, and road load. The equations of motion are derived from dynamic model. The GUI computer simulation program has been developed to analyze the powertrain performance of the vehicle with the Ravigneaux type automatic transmission.

In this paper, a new algorithm is proposed to obtain important corner and real corner points of the simple objects and the visual robot graphics simulation using the results is studied. This is capable of performing as a debugging tool for task programming of a visual robot. And the robot motion is also simulated on a CRT terminal.

This paper concerns the development of NC programming system TIG (Turning with Interactive Graphics) with interactive graphics for turning operation. The system cosists of the processor, the post-processor and the system-user interface. Different from previous segment contour based NC graphic programming systems, the frliability and efficiencyof programming is realized by using Boolean operation with block unit based ICONs for the geometry definition. The tool motion can be also displayed on the screen together with the part contour. The system calculate automatically the number of passes based on the user specified cutting conditions.
