Metabolic cost during walking is positively linked to exercise intensity. For a walking assistive device, one of the major aims should be the maximization of wearers' metabolic benefits for different walking situations. Toward this goal, this paper experimentally evaluates the influence of an authors' soft robotic suit, which has been developed to assist hip flexion for energy-efficient walking of elderly persons in daily life activities, on metabolic cost reduction in the long-distance level and inclined walking. Experiment results show that, for a 79-year-old healthy male subject, the robotic suit significantly reduced metabolic cost in the condition of the robotic suit worn and powered on compared with the condition of worn but powered off.
行走过程中的代谢成本与运动强度呈正相关。对于步行辅助设备而言，主要目标之一应该是在不同步行情况下最大化穿戴者的代谢益处。为了实现这一目标，本文通过实验评估了作者开发的一种软机器人套装对长距离水平行走和斜坡行走中代谢成本降低的影响，该套装旨在辅助老年人在日常生活活动中进行节能行走时的髋关节屈曲。实验结果表明，对于一名79岁的健康男性受试者，与仅穿着但未通电的情况相比，穿着并开启机器人套装的情况下，该套装显著降低了代谢成本。
