About

Tomohiro Nishikawa is a robotics researcher whose work bridges dynamic locomotion control, assistive robotics, and brain-machine interfaces (BMI). His primary research areas include legged locomotion, particularly stable dynamic walking in quadruped robots, and the development of intelligent mobility aids for elderly and disabled individuals. Nishikawa’s most significant contribution is the creation of the quadruped robot “Kotetsu,” where he pioneered a phase modulation controller based on leg loading and unloading. This approach enables seamless integration of posture and rhythmic motion control, allowing the robot to maintain stable walking even under lateral perturbations—a foundational step toward general legged locomotion controllers. His work on the “Kotetsu” platform has garnered over 30 combined citations, reflecting its influence in the field. Beyond legged robots, Nishikawa developed an omnidirectional wheelchair-typed robot with admittance control, providing both walking support and power assistance, a novel contribution to assistive robotics. He has also explored real-time BMI control systems using EEG signals for rehabilitation and power support. Nishikawa’s research demonstrates a consistent focus on practical, human-centered robotics, from stable quadrupedal gaits to intuitive assistive devices, making his work valuable for students and researchers interested in locomotion control and rehabilitation robotics.
