The purpose of this study is to obtain the age characteristics of the human arm motion area for constructing a manipulator system, which having the same characteristics. In order to explore the basic data for constructing the manipulator, a human arm motion experiment was conducted. In this experiment, the motion of transferring an object on a table was employed as a farget motion; especially the data about the characteristics of the area of using the right arm were collected.Bejore the experiment, dual manipulator system based on human arm size was constructed in order to introduce the characteristics of' human arm motion. The analysis of human arm motion revealed that the area where the 50% using of right arm. The subjects of this experiment were elderly people and young people. Comparing the data of young and elderly people, we clarified the age characteristics ojthe human arm motion area.
In this study, we conducted a subjective evaluation experiment of a dual manipulator, which exhibits different motion characteristics. There are three motion characteristics: two of which are age-related, and the third is a robot motion characteristic and is newly added to these two motions. The motions are evaluated from motion areas and motion velocities. Subjects are elderly and young people, and the impressions of the motions are compared in two of the different age groups by the Semantic Differential (SD) method. The obtained results indicate that there are age differences in the evaluation of three manipulator motion areas. The elderly people show a higher reliability and a higher familiarity in a robot motion area than in the other two motions. The elderly people seem to be more affected by the manipulator motion than the young people. Therefore, a careful consideration is required when planning the motion of a manipulator for elderly people.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
