Measures must thus be taken against such vibration. The purpose of this study was to develop stretchers that minimize vibration during transport. This study first details vibration size, direction, and frequency through vibration measurement experiment, resulting in a nonlinear stretcher using a vibration isolator. Stretcher performance was then evaluated and confirmed RMS and acceleration PSD. </span>

Tracked vehicles are effective in such environments because the contact pressure of the vehicle can be distributed more widely. To improve mobility, new mechanisms such as serpentine tracked vehicles have been proposed. We previously proposed the flexible mono-tread mobile track (FMT). The first prototype, WORMY, had a mechanical problem when it moves flexing, i.e., track belt interference and derailing. This paper proposes and confirms a new FMT design strategy using a layered structure to reduce space between vertebrae, solving derailing. A new prototype using the layered structure confirmed its mobility. We also used the prototype to evaluate the effectiveness of passive retro-flexion against obstacles. </span>
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
