Conventional McKibben artificial muscles struggle to perform passive elongation movements from their natural length by external forces when air pressure is not applied. This feature limits the application of these muscles in musculoskeletal robots, where mutual interactions between artificial muscles occur. To address this problem, we proposed a back-stretchable McKibben muscles (BSM), which can perform the passive elongation movements. We investigated the static characteristics, however, the dynamic characteristics of BSMs were not discussed. Its dynamic characteristics are a significant evaluation index when applying the BSMs to actual musculoskeletal robots. In this paper, we investigate the dynamic characteristics of BSMs by comparing the length of the BSM at pneumatic release and supply.
