The function of the robot living together converges on the problem of communication. We focus on nonverbal communication and relationship between service robots and human. We show nonverbal communication experiments of robot to build relationship between human. We described some ideal fiction robots to live with. We got experience such as; Relationship based on touch communication is managed three elements, appearance, motion and predictable behavior. As the result, these elements are based on embodiment. Human touches robot after feeling safe and natural motion. Motivation to build relationship with robots is decided above three elements in physically but appearance and motion are important. Evaluation of relationship is complicated because relationship grows up depending on spending time and motivation to relate. These experiences were shown by life sized humanoid robot and robot arm in exhibition. Based on these results, evaluation method to understand relationship between robot and human are considered in near future robot development.
