About

Nobuyuki Murai is a leading researcher in the biomechanics of human motor control, with a particular focus on standing stabilization and balance. His work centers on the macroscopic dynamics of the human body, using the center of mass (COM) and zero-moment point (ZMP) model—a framework originally developed for humanoid robotics—to understand how humans maintain upright posture. Murai’s key contributions include developing novel identification methods for the human standing controller, treating the body as a dynamical system rather than focusing on individual joint movements. His 2012 paper on visualizing motor control dynamics and his 2013 reassessment of the COM-ZMP model for lateral standing control each garnered 6 citations, establishing foundational insights. More recently, his 2020 work on identifying COM control behavior as a dynamical system (4 citations) and his 2022 phase-space analysis (2 citations) have advanced the field by modeling the controller as a piecewise-linear feedback system. Murai’s research bridges robotics and human physiology, offering critical insights for designing more stable humanoid robots and rehabilitation technologies. His work is essential reading for students and researchers in motor control, biomechanics, and humanoid robotics.
