About

Kazutoshi Nishii is a robotics researcher whose work centers on intuitive human-robot interaction, whole-body teleoperation, and the design of safe, low-inertia robotic arms for physical human-robot collaboration. His most recognized contribution is the development of the "Marionette System," a novel teleoperation approach that uses a small, humanoid-shaped master device to intuitively control the whole-body motion of a larger humanoid robot. This system, detailed in his 2006 paper "Wholebody Teleoperation for Humanoid Robot by Marionette System" (13 citations), addresses the fundamental challenge of controlling multi-joint robots by allowing operators to physically manipulate a scaled replica, making complex motions more accessible and observable. More recently, Nishii has advanced the field of safe human-robot coexistence through the development of ultra-low-inertia, backdrivable manipulator arms. His 2022 paper on "Low-Inertia Backdrivable Arm Focusing on Learning-Based Control" (2 citations) and his 2023 work on a "Ultra-Low Inertia 6-DOF Manipulator Arm for Touching the World" (2 citations) demonstrate a shift toward creating robots that can safely interact with their environment and humans while maintaining high-speed performance. This work is critical for enabling robots to learn from physical contact with the real world.
