This paper proposes a standing-up motion support system for complete paraplegic patients who cannot stand up by himself/herself due to a spinal cord injury. The standing-up motion is the first step for us to move somewhere inside and outside in our daily life. Therefore, the standing-up motion support is indispensable for patients to promote his/her(More)
This paper proposes a novel gait intention estimator for an exoskeleton-wearer who needs gait support owing to walking impairment. The gait intention estimator not only detects the intention related to the start of the swing leg based on the behavior of the center of ground reaction force (CoGRF), but also infers the swing speed depending on the walking(More)
Biped walking improves the circulation of blood as well as bone density of the lower limbs, thereby enhancing the quality of life (QOL). It is significant not only to healthy people but also to physically challenged persons such as complete spinal cord injury (SCI) patients. The purpose of this paper is to propose an estimation algorithm that infers the(More)
This paper introduces an adaptive lower-limbs assistive device to reduce physical load of a caregiver during transferring an elderly or a physically challenged person between a bed and a wheelchair or between a wheelchair and a toilet seat. Based on our experimental results with our conventional assistive device at a nursing home, the previous assistive(More)
This paper proposes a novel walking support system with the wearable robot called “curara”, which supports the swinging motion of the wearer's leg unilaterally based on synchronization control using a neural oscillator. The effectiveness assessment of the proposed system was implemented through two preliminary walking test stages. In this(More)
