About

Shunsuke Nansai is a robotics researcher whose work sits at the intersection of reconfigurable mechanisms, legged locomotion, and autonomous cleaning systems. His research has made significant contributions to two primary domains: bio-inspired walking robots and service robotics for hazardous environments. Nansai is perhaps best recognized for his extensive work on the Jansen linkage mechanism, a biomimetic leg design renowned for its energy efficiency and deterministic foot trajectory. His dynamic analyses and explorations of adaptive gait patterns have advanced understanding of how reconfigurable one-degree-of-freedom linkages can produce diverse locomotion behaviors across complex terrains, earning over 175 citations across related publications. His 2015 work on multiple gait patterns and gait synchronization further cemented his influence in legged robotics. Equally notable is his pioneering work in robotic cleaning systems. His highly cited 2016 survey of wall-climbing robots (121 citations) has become a key reference in the field, while his innovative hTetro floor-cleaning robot — inspired by Tetris and capable of shape-shifting between seven tetromino configurations — reflects his creativity in reconfigurable design. His façade-cleaning robot research directly addresses real-world safety challenges in high-rise building maintenance, demonstrating a consistent commitment to translating novel mechanisms into practical, impactful solutions.
