About

Yo Sakaidani is a robotics and mechatronics researcher whose work centers on the design, analysis, and control of multi-degree-of-freedom (multi-DOF) spherical actuators — compact, high-efficiency alternatives to conventional multi-motor drive systems used in robotics and industrial machinery. His most influential contribution, "Experimental Verification of Feedback Control of a 2-DOF Spherical Actuator" (2014, 27 citations), demonstrated that a single spherical actuator could replace multiple conventional single-DOF motors, addressing long-standing challenges of mechanical complexity, weight, and inefficiency in robotic systems. Sakaidani has further advanced the field through rigorous experimental evaluation of static characteristics and the development of standardized evaluation methods for multi-DOF spherical actuators under power control, both published in 2017. His 2016 work on cogging torque compensation represents an important step toward precise position control, tackling a key practical obstacle to real-world deployment. Collectively accumulating nearly 50 citations, his research has meaningfully shaped understanding of how spherical actuators can be practically implemented and controlled, offering a valuable foundation for students and engineers pursuing next-generation compact robotic actuation solutions.
