About

R. Mukundan is a pioneering researcher whose work has fundamentally shaped the understanding of robotic kinematics, redundancy, and nonlinear dynamics. His key research areas include screw theory, dual-number methods for robotic motion, and the control of kinematically redundant robots. Mukundan’s most influential contribution is his seminal 1989 paper, “On the Use of Dual-Matrix Exponentials in Robotic Kinematics,” which demonstrated that a screw displacement can be elegantly represented as the exponential of a dual skew-symmetric matrix—a foundational insight that has garnered 30 citations and continues to inform modern kinematic analysis. He also introduced the critical concept of “crippled motion” in robots (1988, 28 citations), exploring how redundant degrees of freedom can keep a robotic arm operational after joint failure, a pragmatic advance for fault-tolerant robotics. His later work on chaotic zero dynamics (1991, 8 citations) integrated feedback linearization with redundant robot control, revealing complex internal behaviors that are essential for designing stable, high-performance systems. With a career spanning foundational theory to practical control challenges, Mukundan’s research remains a vital reference for students and engineers working at the intersection of geometry, dynamics, and robot reliability.
