About

Masao Saida is a leading figure in the field of passive robotics, with a particular focus on the design and motion control of caster-type passive mobile robots. His work centers on a novel concept: using servo brakes to control a robot’s motion, rather than active motors. This approach allows robots to respond safely and intuitively to human-applied forces, making them ideal for physical human-robot interaction (pHRI). Saida’s major contributions include the development of the Caster-Type Passive Robot Porter (C-PRP), a platform that can perform path tracking, gravity compensation, and collision avoidance solely through brake control. His research has also advanced the theoretical understanding of feasible braking force and moment sets, enabling precise motion control for robots with multiple caster units. With his most-cited paper, "Motion Control of Caster-Type Passive Mobile Robot with Servo Brakes," garnering 13 citations, Saida’s work has laid a critical foundation for safer, more compliant robotic assistants. His innovative use of risk-sensitive optimal feedback control further demonstrates his commitment to creating robots that can anticipate and adapt to human behavior, a key challenge in modern robotics.
