About

Yoshinori Kobayashi is a robotics researcher whose work spans mobile robot locomotion and human-robot interaction. His most recognized contribution is the development of the "surface walker," a novel hemispherical mobile robot introduced in 2009 that has garnered 17 citations. This innovative system employs a hemisphere-shaped shell paired with a two-degree-of-freedom internal pendulum mechanism, operating under rolling contact constraints to achieve non-holonomic locomotion — a meaningful contribution to the field of unconventional robot mobility. The surface walker represents a creative approach to constraint-based motion control, offering new possibilities for how robots can navigate physical environments without traditional wheel or leg configurations. More recently, Kobayashi has expanded his research interests toward socially integrated robotics, contributing to the design of wheelchair-mounted navigator robots intended to operate cooperatively with people in public spaces. This 2019 work reflects a broader trajectory in his research toward human-centered systems that bridge mechanical engineering and social interaction. Though this more recent work is still gaining recognition within the community, it signals Kobayashi's commitment to developing robots that are not only mechanically sophisticated but also practically beneficial to human users in everyday environments.
