The main researches are focused on System Integration of automated elements (Controller, Actuator, Mechanism, and Sensor) toward an automated system. The characteristics and interface integration of PLC/PC based controller, Motor/Pneumatics actuators, industrial sensors, optical inspection module/ systems are investigated. The applications of intelligent theories such as Fuzzy controls, neural networks, GA, grey relation analysis are also studied for optimal processing. Additionally, some studies include automated optical inspection technique development and applications for industry. The current research issues include Color 3D printer development, automated engineering, and optical inspection applications.
