About

Hitoshi Doki is a researcher specializing in the design and control of robot manipulators, with a focus on optimizing both mechanical and dynamic parameters for enhanced performance. His work bridges robotics and control theory, particularly through the application of Linear Matrix Inequalities (LMI) to simultaneously optimize structural design and gain-scheduling control systems. Doki’s research also explores the spatial expression of upper limb manipulation ability, using six-dimensional ellipsoids to account for asymmetries in maximum joint torque—a contribution that links robotic manipulation to human biomechanics. Although his most-cited papers, such as those from 2004, 2006, and 2007, have modest citation counts (2–3 each), they lay foundational groundwork in global optimal design of dynamic parameters and manipulability indices. His notable achievement includes proposing a unified framework for optimizing robot manipulators’ physical and control parameters, which has implications for more efficient and adaptive robotic systems. Doki’s work is particularly valuable for students and researchers interested in the intersection of mechanical design, control systems, and human-inspired manipulation.
