About

Akira Otsuka is a robotics and biomedical engineering researcher whose work sits at the intersection of human-machine interaction, rehabilitation technology, and assistive robotics. His research has made notable strides in harnessing electromyography (EMG) signals to develop intelligent systems that restore and support motor function in individuals with physical disabilities. Otsuka's most influential contribution is the Cybernetic Rehabilitation Aid (CRA), a pioneering system that integrates direct teaching, tactile feedback, and EMG-based motor skill evaluation to simultaneously assess and improve patients' motor abilities during rehabilitation training — a concept that has earned him 28 citations and marked a significant conceptual advance in the field. Complementing this work, his EMG-based feeding support robot, which applies probabilistic neural networks to assist individuals with severe paralysis, has garnered 18 citations and demonstrates the real-world clinical potential of his research. Earlier in his career, Otsuka laid important groundwork through meal-assistance manipulator systems and a biomechanically informed prosthetic hand design grounded in three-dimensional grasping analysis. Across his body of work, Otsuka has consistently prioritized user-centered design, bridging engineering innovation with meaningful improvements in the daily lives of people with motor impairments.
