Abstract

This paper introduces a passive wearable walking support system and proposes its control algorithm by using servo brake. According to the analysis of the walking of the human, we found that the joint moment around the knee joint is large for supporting the weight of the human during the walking. Consequently, this paper focuses on the development of the passive wearable device with servo brake and proposes the control method for supporting the weight of the user based on a human model. Experiments using the developed device also illustrate the validity of it.
