About

Takumi Katagiri is a pioneering researcher at the intersection of human-robot collaboration and sensorimotor augmentation. His work centers on developing avatar robot systems that enable collective human expertise through shared control, fundamentally rethinking how multiple users can seamlessly integrate their actions into a single robotic body. In his most cited work, "Collaborative Avatar Platform for Collective Human Expertise" (2021, 18 citations), Katagiri demonstrated a system where two users are merged into one robot arm, dividing roles to overcome individual biomechanical limitations and achieve flexible, coordinated movements beyond human range. His follow-up study on sensorimotor control sharing with vibrotactile feedback (2022, 15 citations) further advanced this paradigm, allowing two operators to jointly control a 7-DoF robotic arm by sharing control roles and receiving tactile cues for enhanced body integration. Katagiri also explored shared tactile perception based on skin vibration (2020, 5 citations), showing how partners can partially observe each other’s state through transmitted touch, expanding cooperative work possibilities. His contributions are foundational to the emerging field of multi-user avatar robotics, with potential applications in teleoperation, assistive technology, and collaborative manufacturing.
