Evaluation of virtual and real robot based on human impression

Recently, human-friendly robots such are mainly focused on their functions. And, based on these functions, many researchers have tried to realize good applications for convenient human life. While, a mental safety and affinity for human are also important topics to co-existence with robots. The evaluation techniques of robot motion and design are necessary to consider the above things. However, the costs of real robot are very expensive. So, it is difficult to evaluate human impression for several real robot. So, to solve this problem, we have focused on the evaluation techniques by using virtual reality. In the previous work, several types robot design were evaluated on virtual reality by using meta model, which is abstraction model of robots. When researchers want their robot to reflect an evaluation result on virtual reality, there are some relationships between virtual robot and real one. If there is no relation from real robot and virtual one, we cannot do any feedback to real robots based on virtual one's results. In this paper, we evaluate the relationships between virtual robot and real one based on human impressions through several experiments.
