Abstract
Muscle weakness of lower limbs due to aging interferes with independence activity. The purpose of this paper is maintenance and improvement of function of mind and body to those who care mild. Therefore, we develop a walking assistant orthosis. This orthosis need compact, lightweight and wearable. So, we use actuators which are lightweight, high-output pneumatic artificial rubber muscle. In this paper, in order to downsize equipments installed orthosis, we focused on the air consumption of the artificial muscle and amount of air supplied to the artificial muscle. First, we experimentally confirmed that artificial muscles can reduce the air consumption by thinner and residual pressure. Second, we experimentally confirmed that dry ice as a compressor was effective.
