Akinori SEKIGUCHI

About

Akinori Sekiguchi is a robotics researcher whose work spans two fascinating and complementary domains: chaotic motion control for mobile robots and biomechanically inspired locomotion for humanoid systems. His most celebrated contribution, "The Chaotic Mobile Robot," first introduced in 1997 and refined through subsequent publications accumulating over 165 citations, pioneered a framework for endowing mobile robots with controllers that produce deterministic yet unpredictable motion — leveraging topological transitivity and sensitive dependence on initial conditions for practical robotic applications. This work established him as a leading voice in nonlinear dynamics applied to robotics behavior generation. Sekiguchi also made significant strides in humanoid locomotion, addressing the long-standing challenge of controlling robots through kinematic singularities — specifically, the extended-knee posture natural to human walking. Through his Singularity-Consistent method and inverted pendulum models, he developed walking pattern generators that enable more natural, energy-efficient bipedal gait, contributing across multiple publications between 2006 and 2007. His 2008 work on a skincare robot further demonstrates his versatility, applying robotics to assistive care for elderly individuals. Collectively, Sekiguchi's research reflects a commitment to bridging theoretical nonlinear dynamics with tangible, human-centered robotic solutions.
