Prof. Christos Spitas, Nazarbayev University, Kazakstan
Speech Title: High-performance actuation technologies for machine foundations, robotics and space satellites
Biography: Prof. Dr. Christos Spitas is professor of Machine Design at Nazarbayev University, leader of the Space Technology Research cluster and head of the Machine Design laboratory in Astana, Kazakstan. During the past 18 years, also in his previous positions as professor of Embodiment Design and head of the Product Engineering section at Delft University of Technology and as manager R&D in the high-tech industry, he has developed with his teams a number of technologies on compact, high load capacity, high efficiency, high accuracy mechatronic systems based on multiphysical principles of mechnical contacts and mechanisms, hydraulics, piezoelectricity, and thermal expansion/ morphing. These principles are combined with composite and smart meta-material topologies, incl. particle- and directional-fibre-reinforced and graded polymer- and metal-matrix composites, flat and spatial honeycombs, and frequency-tuned damping-, strength- and stiffness-optimised structures. The primary fields of application have been space satellites, precision machines, mechanical transmissions, machine foundations and alignment systems, and robotics, in the context of several JIPs, as well as national and EU-funded projects with partners such as CERN, ESA, Kazakh Space Agency, Toyota, Kawasaki, etc.
Abstract: The talk will discuss case studies related to the use of thermo-mechanical, hydraulic and piezoelectric actuation principles for the design of machine foundations, vibration test beds, ultra-high precision robotic FMS and space satellite systems from the portfolio of the Space Technology Research Group at Nazarbayev University and work done previously at the Delft University of Technology and IMMG. The different physical principles enabling the various technologies will be classified and explained and their fitness-for purpose in different application contexts will be discussed. Finally, the directions for future research of the Space Technology Research Group on actuation technologies will be discussed as well.

Abstract: Internet of Things (IoT) is the network of physical objects or "things" embedded with electronics, software, sensors, and network connectivity. It enables the objects to collect, share, and analyze data. The IoT has become an integral part of our daily lives through applications such as public safety, intelligent tracking in transportation, industrial wireless automation, personal health monitoring, and health care for the aged community. IoT is one of the latest technologies that will change our lifestyle in coming years. Experts estimate that as of now, there are 25 billon connected devices, and by 2020 it would reach to 50 billion devices. This talk aims to introduce the design and implementation of IoT signal processing systems. The foundations of IoT will be discussed throughout real applications. Challenges and constrains for the future research in IoT will be discussed. In addition, research opportunities and collaboration will be offered for the attendees.
Assoc. Prof. Ratchatin Chanchareon, Chulalongkorn University, Thailand
Speech Title: Liquid Deposition Modeling (LDM) and 3D printing service at Chulalongkorn University
Biography: 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.
Abstract: Liquid Deposition Modeling (LDM) is a technique in Additive Manufacturing (AM) that’s fabricate a 3D object from dense paste of clay-like material such as ceramic, silicone, and chocolate. The talk covers the basic principle of the technique, its benefits compared with Fused Deposition Modeling (FDM), and the real problems and challenges within. Various dense paste extrusion techniques are briefly presented with their pros and cons. Various fabrication print heads, developed at Chulalongkorn university, are revealed. The 3D printing ecosystem and the collaboration projects at the university is also mentioned in the talk.
