This paper presents an artificial intelligent model for a soccer robot We classified soccer robot as artificial intelligent model into three elemental groups including instinct, intuition and reason. Instinct is responsible for keeping the ball, walking or rushing toward the ball This is very simple fundamental action without regard to associates and enemies. Intuition contributes to the faster/slower moving and simple basic tuning to get near to the ball and to make a goal noticing associates and enemies. Reason is. the most intelligent part, the law of reason is not simple relatively with instinct and intuition. We shall expect to design the best law of reason for a soccer robot some time. We also compared nerve system and muscles of human being model with controller and motors of a physical soccer robot model individually. We had designed several algorithms and made programs to investigate effects and control soccer robot.

In this study, effects of silicon addition on the spheroidizing annealing of hyper-eutectoid steel was investi-gated,Heat treatment at various temperatures in they +θ region was also conducted in order to systematically control the kinetics of undissolved cementite. It was found that amount of Si addition could increase both A1 and Acm transformation temperature by both the JMat Pro evaluation and dilatometric measurement. It was also revealed by the microstrural observation that the volume fraction of retained cementite during heat treatment increased with decreasing temperature as well as increasing Si content. Based on the results obtained, it could be suggested that sphe-roidization at relatively higher temperature above 950℃ could be achieved by small addition of Si.

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.
