Abstract

Case of patients with weakness in cardiopulmonary system, other ambulatory function is normal, but oxygen supply function is problem. So they need reduce energy consumption for gait by assistance system. In this study, we designed and developed walking assistant device which helps flexion and extension of hip joint for cardiopulmonary patients. There are two motors, each at the left and right side of pelvis, providing torque to the hip joint. The target angle of the flexion and extension in the hip joint is set according to the normal gait. As a result, reduction of energy consumption was 14.8% by gait assistive device.

심폐기능 허약자의 경우 다른 보행기능은 정상이지만 산소 공급에 문제가 발생된 경우로서, 에너지 소모를 최소한으로 줄여주는 보행보조 시스템이 필요하다. 심폐기능 허약자의 보행을 원활히 보조하기 위하여 본 연구에서는 고관절에 부착된 DC모터를 이용하여, 보행시 고관절 굴곡 및 신전을 제어하는 시스템을 고안하였다. 두 개의 모터를 좌우 고관절에 부착되어 정상 보행패턴을 기준으로 고관절의 굴곡과 신전의 설정각도를 정의하고 보행을 보조한다. 실험결과 보행보조에 의한 에너지 소모도 감소는 14.8%이었다.
