As birth rates drop and societies age, the physical burden on long-term personnel grows and labor shortages become an increasing problem for society. We developed a practical wearable assist suit that supports motion in an antigravitational direction using electricmotors while ensuring that passive joints do not interfere with wearer motion. Results of experiments show the effectiveness of the proposed wearable assist suit.
