Rehabilitation Robot for Elderly with Estimation of Stride

Abstract

In the literature pertaining to supporting rehabilitation for elderly people, methods such as robot suits and belts has been proposed, however the method to be used casually by individuals is not provided sufficiently. In this research, we propose a rehabilitation robot that allows elderly people to perform rehabilitation individually. Specifically, the robot provides adaptive motion according to the stride of a person, based on the estimation of stride length by a statistical method. We develop a prototype of a rehabilitation robot that assists the movement of people, based on the estimation of the stride. To evaluate performance, we evaluate the ratio of recall and relevance rate of the proposed rehabilitation robot, with the proposed method that based on the estimation of stride length. The result shows that the effectiveness of estimation.
