About

Kazuo Hongo is a robotics researcher whose work spans musculoskeletal humanoid robotics, haptic sensing, and human-robot interaction. He is perhaps best known for his contributions to the Kojiro project, an advanced musculoskeletal humanoid robot designed to mimic human biomechanics through tendon-driven actuation, redundant degrees of freedom, and coordinated spine-leg motion — work that has accumulated over 160 citations and helped establish foundational design principles for human-symbiotic robots. His research extends into the control challenges unique to musculoskeletal systems, including joint proprioception acquisition, automatic parameter adjustment for reflexive walking, and modular actuator design that allows flexible muscle layout optimization. Beyond humanoid robotics, Hongo has made notable contributions to surgical and manipulation technologies. His development of fiber Bragg grating-based force-sensing forceps for bilateral micro-operation systems addresses critical needs in precise robotic surgery, while his bilateral wearable device "Kento" — which uses stiffness-adjustable muscle-actuator modules — demonstrates innovative approaches to human-guided robot teleoperation. His multisensory robotic hand work further reflects a commitment to robust real-world manipulation. Collectively, his research bridges biomechanically inspired robot design with practical sensing and control solutions, making meaningful contributions to the fields of service robotics and medical robotics.
