About

Ojiro Matsumoto is a rising researcher in bio-inspired robotics, focusing on how animal anatomy and dynamics can transform quadrupedal robot locomotion. His work centers on two key innovations: spine-driven speed and energy-efficient mass distribution. In his 2023 paper on a high-speed running quadruped robot, Matsumoto introduced a feline-like multi-joint spine using a one-degree-of-freedom closed-loop linkage, achieving remarkable running speeds by mimicking the spinal flexion of real animals. This work, with 8 citations, lays a foundation for more agile, animal-like robots. Complementing this, his 2023 study on a swinging mass for energy-efficient locomotion—drawing inspiration from the soft abdomens of dogs—shows how passive body dynamics can reduce energy costs, earning 4 citations. Most recently, in 2024, Matsumoto advanced postural stability by integrating tension feedback into central pattern generator (CPG)-based controllers, addressing a critical gap in musculoskeletal quadruped control. With 3 citations, this work enhances robot adaptability in unstructured environments. Matsumoto’s contributions are steadily building a bridge from biological principles to practical robotic performance, making him a promising voice in the field of legged robotics.
