Analysis of a design index for the service robot in a human-coexistence environment

In recent years, service robots are required to execute various tasks in a human-coexistence environment. These robots should be designed not to induce discomfort and aversion in people who use them. To realize this, we focus on the design method for the service robot which runs around in a public space. These service robots should avoid giving a negative impression to these people. Thus, in this paper, we investigate pairs of polar adjectives which consist of the robot´s body with a questionnaire employing 142 subjects - 92 men and 50 women - aged 18 to 63. The answers of this questionnaire reveal 22 appropriate pairs of polar adjectives which are suitable for a psychological assessment of subjects who use the robot or coexist around the robot. Furthermore, using them, we investigate a potential which realizes the proposed service robot´s design method for giving a positive impression to people.
