  • Biography

    Yuki's research focuses on planning, estimation, and control for contact-rich manipulation and locomotion, from spanning free-climbing robots to robotic tool manipulation. In particular, he has been working on contact-implicit trajectory optimization, stochastic optimization, contact modeling, and contact estimation using tactile sensing. His current research interests lie in the intersection of optimization and learning.
