In recent years, along with the development of robot technology, it has become possible to move dolls and toys realistically. Robot therapy is expected to achieve similar effects to those of animal therapy. However, which element of a robot is important for robot therapy has not been examined. We surmise that humans obtain more emotional healing based on biological functions related to hugging a doll with similar size and weight to those of a human baby. This paper describes analyses of the relation between human impressions and elements of the object such as size, weight, motion, and touch. The experimentally obtained results for human impressions using dolls of five kinds, including a robot, were evaluated. The results show that motion, tender touch, sufficient size to be hugged, and weight suggestive of a human baby all gave humans good impressions.
