Abstract
Beautiful writing is impossible when paresis occurs due to diseases such as stroke. Writing is an indispensable motion on Activities of Daily Living (ADL). We aim to develop write-assist system using finger exoskeletal robot. This paper presents an investigation about finger support method for the write-assist system. Specifically, we analyzed the characteristics of gripping force using a pen on the writing task. It was found that the difference of thumb and index finger force tended to be small on beautiful writers. We will apply this result to the control method of assist robot.
