Abstract
In recent years, patients who are not able to move their bodies because of accidents, aging, and disease have been increasing. This rise leads to many patients are not being able to do their ADL (Activities of Daily Life) every day. If the patients are not able to do their daily activities, supporting their activities every time will be a huge burden to the nursing department and other people related to them. In this study, we have developed a simple and compact device that will care the patients' daily activities by supporting their upper arms. When constructing this device, we have created a human model based on the human characteristics, and completed the device so that it matches the characteristics upon the study of human mechanics. By choosing to use a pneumatic cylinder instead of a motor for the better weight-to-output ratio, we can expect flexibility and relied safeness of the device due to the cylinder's ability to control the compression of air. We adopt position control and compliance control for this device to realize two functions, 1 e, living assistance mode and rehabilitation mode We also created a control box that is easy to carry and operate In addition, this device was evaluated by professionals such as doctors. We show the evaluation results.
