Dr. Ratchatin Chancharoen is currently an Associate Professor at the Mechanical Engineering Department, Chulalongkorn University, Thailand. He received his BS degree in mechanical engineering from Chulalongkorn University in 1991, MS degree in mechanical engineering from Oregon State University in 1994, and PhD degree in mechanical engineering from Chulalongkorn University in 2000. Dr. Ratchatin Chancharoen has twenty years experience in robotics research including both manipulators and mobile robots and ten years in teaching both Robotics and Mechatronics at the university level. During these years, he has designed and built more than twenty robots in various configurations and published more than 20 research papers and one text book entitled “Linear Control Systems” (in Thai). He is principal investigator and co-investigator of a number of research grants in robotics and also the manager of a number of industrial projects in design and control. His major research activities involve tele-operation and control of robotics manipulators and mobile robots using various kinds of sensors, especially force and vision. His current research is the design a telerobot, a new type of robot, to work closely with human to do a higher level of tasks. The telerobot is designed with lighter frame, less power consumption, small footprint controller, and higher level of intelligence, compared to the industrial robot, to safely work in our working space. This type of robot will be populated in the near future as more complex tasks are demanded. His main research interests are in the field of Robotics and Mechatronics including new parallel robot configuration, new hardware processor, electronics, control algorithm, and intelligence.
