About

Takayoshi Hagiwara is pioneering the future of human-machine collaboration through his groundbreaking work on **shared avatar control and collective human expertise**. His research fundamentally reimagines how multiple people can jointly operate a single robotic body, creating a new paradigm where two users are integrated into one robot arm to collaborate seamlessly. In his most-cited work (2021, 18 citations), Hagiwara developed a collaborative avatar platform that divides control roles between users, enabling flexible movements that transcend the natural limitations of a single human arm's range and rotational freedom. He further advanced this concept by incorporating **vibrotactile feedback** (2022, 15 citations) to enhance body integration and sensorimotor control sharing, allowing multiple operators to intuitively feel and coordinate their actions through a 7-DoF robotic arm. Hagiwara has also explored the social dynamics of this technology, investigating how partners recognize each other during collaborative avatar manipulation (2024, 5 citations) and developing adaptive shared body control methods using EMG sensors (2021, 4 citations) to improve coordination when operators perform different actions. His work sits at the exciting intersection of robotics, haptics, and human-computer interaction, with profound implications for remote collaboration, assistive technology, and collective problem-solving.
