Subjective evaluation of motion characteristics of dual manipulator in young and elderly people

In this research, we conduct a subjective evaluation experiment of a dual manipulator, which poses different motion characteristics. There are three motion characteristics, and two of them were age related characteristics. These motions are constructed using the data obtained from previously conducted human arm motion experiment. Another motion is defined as a robot motion characteristic, and newly added to these two motions. Subjects were elderly and young people, and the evaluations of the motion´s impressions are compared in two different age groups. Results indicated that there are age differences of evaluation between three types of manipulation´s motions. Elderly people show more reliability and familiarity in a robot motion than that of the other two motions. In addition, elderly people seem to be more influenced by manipulator´s motion than that of young peoples. Therefore, we need more consideration when we make motion planning of manipulator for elderly people.
