Development of an assist suit to support elbow joints for underwater work

-Verification of assist effect for rolling work based on electromyogram and expired gas analysis-

Abstract

When constructing marine infrastructures, the foundation stones that have been dropped into the sea are leveled manually by divers. At this time, a large strain is placed on the diver’s body. Therefore, in this study, an assist suit for elbow joints that can be used underwater was developed to reduce the burden on the diver’s arms. In order to evaluate assist effects of the developed assist suit, experiments of measurement of electromyogram and expired gas analysis were carried out. From the experimental results, reduction of the physical burden on the subjects was verified for the rolling work of the heavy object.
