上向き作業用アシスト装置の改良および可動型ヘッドレストの開発

抄録

In our previous study, the upper arm assist device was developed for assisting upward work such as fruit harvest and tension ceiling. In this study, the problems of the developed upper arm assist device were improved. In addition, to reduce the burden on the neck during the upward work, a headrest which can be attached to the upper arm assist device was developed. In order to evaluate assist effects of the improved assist device and the built headrest, experiments of measurement of electromyogram and muscular stiffness were conducted. From the experimental results, reduction of the burden on shoulders and neck during upward work was confirmed. Thus, the effectiveness of the improved upper arm assist device and the built headrest was verified.
