------Professor Jian Sheng Dai received his BSc in Mechanical Engineering in 1982 and his MSc in Machine Systems in 1984 at Shanghai Jiao Tong University in Shanghai. He was appointed Lecturer in Mechanical Engineering in 1985 and joined the University of Salford in the UK in late 1980s as a research scholar in the area of kinematics, mechanisms and robotics, and then received his PhD. Since then, he has spent time in industry and led an international project on dexterous reconfigurable assembly and packaging technology together with Prof Makino in Japan in 1996 and 1997.
------Professor Dai is Chair of Mechanisms and Robotics and the Director of Centre for Mechatronics and Manufacturing Systems (CMMS). Working in the field of mechanisms and robotics in past 25 years, he is an international leading figure in mechanisms and robotic end-effectors and a pioneer in reconfigurable mechanisms. He has published over 250 peer-reviewed papers and held five patents. He has supervised/is supervising over 18 PhDs, 10 post-doctoral researchers and 12 visiting scholars. Since 1996, he has been developing novel mechanisms and manipulators with reconfigurability and dexterity and has been working on multidisciplinary tasks on rehabilitation devices, handling devices and packaging devices. He was recipient of ASME biennial mechanisms conference best paper award in 1998 on metamorphic mechanisms and recipient of the 2009 PE publishing best journal paper award. He is a Fellow of the Institution of Mechanical Engineers (IMechE), and member of a number of international leaned societies committees. He has been referee and panelist for China NSFC and Canada NSERC, and evaluator and panelist of European Commission FP7 programme and serves as Associate Editor of IEEE Transactions on Robotics, Associate Editor of ASME Transactions: Journal of Mechanisms and Robotics and Associate Editor of international journal Robotica.
------Prof. Jian S Dai focuses on screw theory, line geometry, metamorphic mechanisms, reconfigurable mechanisms, grasping theory, multi-fingered robotic hand, robotic devices for sprained ankle rehabilitation, surgical robots and automated assembly and packaging systems. He has patents on metamorphic robotic hand and linear actuator and rehabilitation device. Pioneering in reconfigurable mechanisms, he organized the first ASME/IFToMM International Conference on Reconfigurable Mechanisms and Robots (ReMAR 2009). In the past years, Prof Dai has been invited to serve on technical committees and programme committees of over 40 international conferences and chair a number of ASME symposia and over 30 sessions in the prestigious international conferences. Prof Dai has been invited to take visiting professor at many universities and research institutes including Institut Francais de Mechanique Avancee and adjunct chair professor at Italian Institute of Technology.

------Mechanisms are fundamental parts of a machine used in both industrial and domestic environments and essential parts of a robot. The strong science elements have been reflected in the application of various mathematical tools in the mechanisms development which forms a fundamental basis of mechanical engineering, manufacturing engineering, instrument engineering, control engineering and other disciplines. This can be dated back to the 18th and 19th centuries when applied mathematics was utilized to apply to the analysis and synthesis of mechanisms. With the development in mechanisms and robotics, there has been a considerable advance in the relative scientific areas since the mid of 20th century. The application of screw theory, Lie algebra, Lie group, projective geometry and graph theory in the mechanism research has been further developed and vice versa the application study contributes to the these mathematical disciplines by evolving new algorithms and laws and revealing intrinsic properties of these disciplines.
------Mechanisms and mechanism theory are still progressing accompanying with the advancement of science and modern technology. In particular, characteristics of some traditional mechanisms have been investigated and new kinds of mechanisms have been proposed. The new proposed metamorphic mechanism originated by metamorphosis has attracted substantial interests worldwide. This new kind of mechanisms is capable to adapt to various conditions and meet the strong demand of reconfigurability for exploring the disastrous environments and out-space. The study opens up new avenues for applying mechanism theory to achieving innovation in the design of new mechanisms. The 21st century presents a new adventure with its changeable, rapid and highly multidisciplinary development. This puts high demand and pressure in mechanisms development particularly in its use in robotics and manufacturing industry.
------The keynote speech presents the current stage and the development of mechanism research in American, Europe and China, and the application of mechanisms in robotics and manufacturing system and casts the future development in the 21st century. In particular, the study on screw theory and reconfigurable mechanisms is addressed. The exploration of new mechanisms, new methodologies and new amalgamation are specialized. This leads to unraveling the substantial interests of the mechanism research on topology variation, reconfigurability and adaptability. The collaboration of the research on the interdisciplinary subject of mechanisms between affiliations and countries are elucidated. The extensive application of the mechanisms in daily maintenance, industrial engineering and stratosphere are introduced. The application in engineering including food manufacturing, transportation engineering, space technology and environmental engineering, and the special application in medical area for surgical robots are addressed in detail. The innovation in the study of mechanisms is extracted based on the development of reconfigurable mechanisms. This is then focused on the development of metamorphic mechanisms and its application, especially the exploration in reconfigurable manipulators and multi-fingered robot hand. This leads to the fundamental basis for further development of metamorphic mechanisms.
------The new development of metamorphic mechanisms will provide leading-edge methodologies which are commercially exploitable to industrialists who are interested in reconfigurability. The novel robotic hand based on this class of mechanisms takes the advantage of characteristics of mobility change of metamorphic mechanisms to change the structure of a palm during operation. This leads to supplementary mobility, easy grasping and more dexterity of the multi-fingered hand. Metamorphic mechanisms can be developed to surgical robots with multifunction due to the variable topological configurations. This new kind of mechanism can be integrated in the body design of rover mechanism for adaption of various conditions resorting to the link annex of the body structure.
------In the production, metamorphic process was used to make a step change in manufacture that has an effect on nano-manufacture. The integration of metamorphosis and compliance enable structure evolution of manufacturing system. This leads to optimization of process technology and clamps selection, to simplification of manufacturing process and to contraction of production cycle.
------The keynote speech presents the inherent properties of metamorphic mechanisms and the extensive application of the new kind of mechanisms in development of robot manipulators and manufacturing systems. The innovation in mechanism research in the 21st century is addressed and the fundamental basis for the further exploration of metamorphic mechanisms is summarized.
