About

Yuichi Tsumaki is a robotics researcher whose work spans space robot teleoperation, kinematic singularity management, humanoid robotics, and human-assistive systems. He is perhaps best known for his pioneering contributions to space robot teleoperation, most notably through his work on Japan's Engineering Test Satellite VII (ETS-VII), where he developed mixed force and motion command-based teleoperation systems capable of overcoming the critical challenge of communication time delays between ground operators and orbital manipulators — work that has garnered 169 citations and remains a landmark in the field. Tsumaki has also made significant theoretical contributions through his singularity-consistent parameterization framework, which elegantly reformulates inverse kinematics to enable smooth robot motion even near workspace singularities, influencing both industrial and humanoid robotics applications. His creative work on the "Telecommunicator" and MH-2 miniature humanoid systems demonstrated a visionary approach to wearable telepresence, allowing operators to embody remote avatar robots for social communication. Further reflecting his commitment to human welfare, Tsumaki developed a skincare robot addressing the needs of aging populations. His broad portfolio, spanning lightweight wire-driven arms to humanoid walking pattern generation, underscores a career dedicated to making robots safer, more capable, and genuinely useful to people.
