About

Kazuo Sakurai is a leading figure in soft robotics, with a particular focus on the design and control of compliant, bio-inspired actuation systems. His research centers on developing novel actuators that are inherently safe for human-robot interaction, a critical requirement for the next generation of collaborative and assistive robots. Sakurai’s major contribution is the pioneering work on the Twist Drive Actuator, a mechanism that leverages the unique properties of twisted strings to generate linear motion with high force and inherent compliance. His foundational paper, "Modeling and Evaluation of a Twist Drive Actuator for Soft Robotics" (2012), which has garnered 25 citations, provides the first comprehensive model for this innovative actuator, establishing a key design principle for the field. This work has been instrumental in shifting robotic actuation away from rigid, high-impedance systems toward safer, more adaptable alternatives. By enabling robots to operate with the gentle, forgiving touch required for direct physical collaboration, Sakurai’s research is paving the way for robots that can safely work alongside humans in homes, hospitals, and factories.
