About

Tsubasa Suenaga is a pioneering robotics researcher whose work centers on novel actuator design and its application to humanoid locomotion. His key contributions lie in the development and control of the spiral motor—a unique, contactless electromagnetic actuator featuring a helical mover and stator. Suenaga’s most cited paper, “Force control of a spiral motor and its application to musculoskeletal biped robot” (2012, 9 citations), introduces a groundbreaking method combining force control with zero-power magnetic levitation to overcome manufacturing-induced neutral point fluctuations. This innovation enables precise, smooth force generation without mechanical friction, directly applied to a musculoskeletal biped robot for more natural, compliant walking. By addressing fundamental challenges in actuator precision and control, Suenaga has advanced the field of bio-inspired robotics, offering a pathway to more efficient, human-like movement in legged machines. His work stands as a notable achievement in merging electromagnetic engineering with biomechanics, inspiring further research into contactless actuation for agile, adaptive robotic systems.
