Libraries which have a large amount of genealogical materials need to manage them in a special way differing from the other materials. Although genealogy related materials have high pragmatic value, the reality is that the acquiring methods are limited to collect the genealogical table or is not systematic. Even the genealogical materials held in the library are not rationally organized. Under such circumstances, this study investigates the cases of the management of genealogical materials both in domestic and foreign institutions, and also examines the real situations of material organization such as the collection, the classification and the cataloging on the centering of the libraries which hold a large amount of genealogical materials. On the basis of this investigation, the study aims to measure the enhancement of the methods for collecting and organizing genealogical materials which enable the collection management and information retrieval fur them to be efficient and effective.

In this paper, we propose a footstep planning method of biped robot based on the Particle Swarm Optimization(PSO). We define configuration and locomotion primitives for biped robots in the 2 dimensional workspace. A footstep planning method is designed using learning process of PSO that is initialized with a population of random objects and searches for optima by updating generations. The footstep planner searches for a feasible sequence of locomotion primitives between a starting point and a goal, and generates a path that avoids the obstacles. We design a path optimization algorithm that optimizes the footstep number and planning cost based on the path generated in the PSO learning process. The proposed planning method is verified by simulation examples in cluttered environments.

As the function and interface for controlling the robot is more complicated, the robot platform which can link effectively between software and hardware is need to develop the robot easily. In this paper, we developed a humanoid robot that interests in robot industry part for robot platform with network communication function.

We developed a motion capture system to get angle data of human joints in the walking mode. The motion capture system is a pair of leg-shape device, which is composed of three links with ankle, knee and pelvis joints. The sensors for measurement of the joint angle are potentiometers. We used an A/D converter to get digital data from joint angles, and which are used to simulate and coordinate the biped-walking robot developed in our laboratory. To simulate and analyze walking motion, animation based on three-dimension motion is performed using the open inventor software.

This hybrid position/force control for the dynamic walking of the biped robot is performed in this paper. After the biped robot was modeled with 14 degrees of freedom of the multibody dynamics, the equations of motion are constructed using velocity transformation technique. Then the inverse dynamic analysis is performed for determining the driving torques and the ground reaction forces. From this analysis, obtains the maximum ground contact force at the moment of contacting which act on the rear of the sole of swing leg and the distribution curve of the ground reaction. Because these maximum force and distribution type acts an important role to the stability of the whole dynamic walking, they are reduced and distributed smoothly by means of the trajectory of the modified ground reaction force. This new trajectory is used to the reference input for more stable dynamic walking of the whole walking region.
