Impression analysis of various humanlike gait patterns

Current technology for designing motions of entertaining robots is developing fast today. Motion planning method that refers to human impression is one of the possibilities to develop robot motions. In this paper, we attempt to find relationships between the kinetic characteristics of humanlike gait as an example of robot motion and the human impression about them. We introduce a semantic differential method and factor analysis technique to find these relationships. We also develop the software to show and modify humanlike gait patterns, with two-dimensional animated stick motions. Subjective evaluation is carried out using this software. Then we found the kinetic characteristics of humanlike gait patterns that give certain impressions to human.
