Professor J.Michael McCarthy is a fellow of the American Society of Mechanical Engineers (ASME) and a world leader in kinematics and mechanisms design. Professor McCarthy received the 2008 ASME Outstanding Service Award, the 2009 ASME Machine Design Award, and the 2011 ASME Mechanisms and Robotics Award for his lifelong contribution to theory and design in mechanisms and robotics. In 2013 he received Robert E. Abbott Lifetime Service Award from the Design Engineering Division of ASME International. He is the Director of UCI’s Performance Engineering Program at the University of California, Irvine. His contributions in teaching were recognized by the Henry Samueli School of Engineering’s 2009 Faribor Maseeh Teaching Award and in 2010 by the UCI Teaching Excellence in Undergraduate Engineering Award.Professor McCarthy has over 150 publications and three books including Introduction to Theoretical Kinematics (1990), and The Geometric Design of Linkages (Springer 2000, 2nd Ed. 2010). These two books have been highly cited in the world. Professor McCarthy served as the Editor-in-Chief of the ASME Journal of Mechanical Design (2002-2007) and is the founding Editor-in-Chief of the ASME Journal of Mechanisms and Robotics (2007-2015).
This presentation describes the modern formulation of the kinematic synthesis equations for four-bar, six-bar and eight-bar linkages that is well-adapted to polynomial homotopy solutions and is providing new opportunities for innovation. The generalization of this approach to spherical and spatial linkages is the focus of current research. An overwhelming challenge is the rapid growth in the degree of the polynomial systems that must be solved and new strategies are needed to make this synthesis methodology useful to designers. At the same time the dramatic increase in the size of the design space for these devices makes computer-based invention a valuable tool for innovation.
