In aging societies, there is a strong demand for robotics to tackle problems caused by the aging population. Patient transfer, such as lifting and moving a bedridden patient from a bed to a wheelchair and back, is one of the most physically challenging tasks in nursing care, the burden of which should be reduced by the introduction of robot technologies. We(More)
In our current research, we are developing a robotic walker system with standing, walking and sitting assistance function. Our developing system is based on a walker which is popular assistance device for aged person in normal daily life and realizes the standing and sitting motion using the support pad which is actuated by novel assistance manipulator(More)
For reducing the risk of pressure sore caused by long period sitting on a wheelchair, we develop a depressurization motion assistance system which is low cost and suitable for practical use. Our developing system consists of a seating cushion which the patient sits on and four air cells which can lift or incline the seating cushion. Each air cell is(More)
For reducing a risk of pressure sore caused by long period sitting on a wheelchair, a patient is required to depressurize buttocks by changing the posture suitably. Thus, we have been developed an automatic depressurization motion assistance system for a seated patient on a wheelchair. In our previous work, we developed a sitting surface coordination system(More)
Recently, the people who are under a lot of stress have increased. Too much stress may cause various physical and/or mental disorders. The final aim of our project is to develop a relaxation machine for reducing stress by using rocking vibration. As rocking vibration, motion of a mother's embracing and rocking of a baby is adopted. In this paper, we analyze(More)
