About

Kento Matsusaka is a robotics researcher whose work focuses on energy-efficient robot motion control, particularly for industrial manipulators. His major contributions center on leveraging mechanical resonance and adaptive counterbalancing to dramatically reduce energy consumption in pick-and-place tasks. In his most cited work (27 citations), Matsusaka demonstrated how adaptive elastic devices at robot joints can store and release energy during periodic motions, enabling SCARA robots to perform high-speed tasks with significantly lower power requirements. He further advanced this concept by developing resonance-based control methods that overcome practical limitations of periodic motion, achieving both high efficiency and task flexibility. Matsusaka also pioneered robotic arms with active movable counterweights (7 citations), which adaptively reduce gravity effects in cantilever structures, and created a novel stiffness adjustment mechanism (6 citations) that maximizes elastic energy utilization through a lead screw and linear spring configuration. His research bridges the gap between theoretical energy efficiency and practical industrial applications, offering concrete solutions for sustainable automation. With over 45 total citations across his core publications, Matsusaka’s work is foundational for next-generation, eco-friendly robotic systems.
