ロボティクスをもとにした自動化の研究でPh. D. を取得。日本学術振興会 特別研究員、ベンチャー企業とのパートナー、大学非常勤講師の経験。
ロボティクスの中でもひととともにはたらくロボット、ひとと同じ道具を操るロボットの研究、3Dプリンタで球体やたまごをつくりそこにセンサーを内蔵の無線計測研究をおこなってきた。これをまとめるとひとの暗黙知を工学に落とし込む研究分野といえる。
これを暗黙知工学としよう。
I received my Ph.D. in Robotics Engineering, focusing on automation technologies and human-centered robotic systems. My experience includes serving as a Research Fellow (DC2) of the Japan Society for the Promotion of Science (JSPS), collaborating with startup companies as a technology partner, and teaching as a part-time university lecturer.
My research has focused on cobots (collaborative robots) that work alongside humans and robots capable of using the same tools as humans, as well as wireless sensing systems in which sensors are embedded within 3D-printed spherical or egg-shaped objects. Taken together, these studies can be viewed as an effort to translate human tacit knowledge into engineering principles and technologies.
I refer to this emerging field as Tacit Knowledge Engineering.
“All truth is one. In this light, may science and religion endeavor together for the steady evolution of Mankind: From darkness to light, from narrowness to broadmindedness, from prejudice to tolerance. It is the voice of life that calls us to come and learn.”

Michael Polanyiは暗黙知理論において
We know more than we can tell.
ことばでは伝えられない暗黙知があるといっている。
暗黙知を計測により定量化し、ひとの熟練のわざをロボットで再現する、
暗黙知工学とは、人間が言語化しにくい経験的・身体的な暗黙知を、ロボット工学や制御工学の手法で解き明かし、体系化・形式知化することで、ものづくりにおける熟練技能の継承、革新を進める学問である。
Tacit Knowledge Engineering Michael Polanyi famously stated: “We know more than we can tell.” Human expertise often contains tacit knowledge—skills and intuitions that are difficult to express through language alone. My research aims to quantify such tacit knowledge through sensing, measurement, and modeling, and to reproduce skilled human behavior using robotic systems. What is Tacit Knowledge Engineering? Tacit Knowledge Engineering is an interdisciplinary field that seeks to reveal, model, and formalize experiential and embodied human knowledge that is difficult to verbalize. By integrating robotics, sensing, control engineering, and data-driven modeling, it promotes both the inheritance and innovation of manufacturing skills and craftsmanship.
