We have been developing a new vehicle, “Tread-Walk 2”, which supports walking for elderly. A control algorithm to improve the operability has been constructed. As the first step, we accurately estimated the user's anteroposterior force from the motor current value without the force sensor. This method is to develop a new mechanical model that considers the friction forces of the treadmill and remove...
To develop a gait rehabilitation robot for hemiplegic patients, quantitative evaluations of patient ability is needed. Patient's walk phase, which includes time balance of stance and swing legs, is one of the most useful indexes. However, conventional methods measuring walk phase require laborious preparations. In this paper, a novel algorithm estimating walk phase on a treadmill by observing DC motor...
The importance on walking for health is growing in elder dominated society. We have been developing a new mobility ldquoTread-Walk 1 (TW-1)rdquo controlled by walking movement. The device uses active treadmill velocity control, which allows the user to walk on the treadmill at any desired velocity. In this paper, the walking movements on the TW-1 were kinematically analyzed and compared with the walking...
In Japan, independent living and freedom of movement are expected, even by aged persons, and the importance of preventive medicine and walking as part of overall efforts to maintain health are continuously promoted. To those ends, we have been developing a new mobility device, known as Tread-Walk (TW), which incorporates the following concepts: ldquoimproved mobility,rdquo ldquohealth maintenance,rdquo...
The development of assistive technologies, especially mobility devices, has an important impact on the daily activities and social participation of elderly people. The authors have developed a new mobility aid, ldquoTread-Walkrdquo, which extends mobility activities, maintains body function and maintains natural walking appearance. In the current research, we designed and developed a more natural...
