The cycling wheelchair is a new type of mobility aid for lower-limb-disabled individuals. Patients can drive the cycling wheelchair by pressing the front pedals with their lower limbs. The device enables patients to effectively rehabilitate their disabled legs and partake in outdoor activities. However, lower-limb-disabled individuals cannot move both legs with equal ease. Typical hemiplegia patients...
Since the cycling wheelchair was introduced in the 2000s, we have focused on alleviating the over-use of healthy limbs that presents a problem to users. To this end, we have been developing assistance control for everyday users of cycling wheelchairs. In our previous research, we found that user load varies in different environments. Traveling resistance compensation control proved successful in counteracting...
In this study, we propose a cycling wheelchair that assists the movement of patients with impairment of lower extremities. The wheelchair is a pedal-driven system, similar to a bicycle, moved by the pedaling force of the patient's legs. Although the lower extremities of patients are impaired, they can use both legs to smoothly rotate the pedal. However, there are several barriers to use the cycling...
Though several kinds of equipment such as wheelchairs and electrical wheelchairs exist to support lower limb disabilities, there were still problems because of disuse of lower limbs that limits effect of rehabilitation and also cause disuse syndrome. To overcome these problems, cycling-wheelchair was invented by Handa et al. It is a pedal-driven wheelchair and can be applied to most of the patients...
Many one-degree-of-freedom (1-DOF) grippers have been used in factories. This paper focuses on the design of the 1-DOF parts handling device for picking up small objects robustly and agilely and realizing assembly tasks. In our conventional research, we proposed a concept for the handling device, which cages an object without letting the object escape from its tips before closing them completely and...
In this study, we consider the development of a device for handling small parts for automatic product assembly in factories. Many robotic hands and one-degree-of-freedom grippers have been proposed as grasping parts; here, we focus on the shape of the tips of a handling device for picking up small parts robustly and agilely. In this research, we propose a concept for a handling device for picking...
