Rapid tooling (RT) has recently become more important due to the requirement of rapid manufacturing. RT can manufacture stronger mold and functional component than rapid prototyping (RP) does. Besides, functional component and production are valued gradually. Functionally graded materials (FGM) technology is proposed to apply to functional component. This(More)
Indoor monitoring system for robot and human is an important issue in robotics research. In this study, we propose an indoor monitoring system based on wireless and pyroelectric infrared (WPIR) sensory fusion system. Pyroelectric infrared (PIR) system alone for localization provides less accurate information of human location and suffers from multiple(More)
