    ABSTRACT: We clarify the basic factors necessary for a symbiotic relationship between humans and robots. However, evaluating interaction between humans and robots is difficult due to a number of uncertain factors in human communication. Therefore, less sophisticated creatures, rats, were first selected, and we conducted interaction experiments between rats and robots. In our previous studies, we could not conduct these experiments for over 2 hours. We then developed a new experimental system to conduct the experiments without time restrictions. Using this system, we conducted two interaction experiments. In one experiment, the robot, meeting a rat's request, could live symbiotically with the rat. In the other experiment, the robot, behaving sequentially without having met the rat, could control the rat. This paper investigates the factors for a symbiotic relationship between a rat and a robot by comparing the two experiments.

    ABSTRACT: The goal of our research is to clarify factors that are necessary for coexistence between human and robot. However, evaluating communications between humans and robots is quite difficult due to the existence of several uncertain factors that exist in human communication and variety of personalities. Therefore, as a first step, a more previous species, rats were selected. We conducted interactive experiments between rats and robots. We investigate basic factors that are necessary for symbiotic relationship between living creatures and robots. To conduct such experiments, we developed a new rat-robot (WM-6) and experiment systems. Three experiments have been conducted: "calling robot", "recognizing behavior", and "choosing reward". The results of these experiments show that we succeeded in making a rat to act on the robot by itself. Moreover, the rat could recognize two behavioral patterns of the robot ("translation" and "rotation"). Finally, the rat could change its interaction with the robot based on its need. Consequently, we succeeded in creating various interactions between rat and robot.

    ABSTRACT: In this paper, we introduce an attempt to realize communication between rats and rat-robots for the advancement of communication between humans and robots. By repeating certain interactions between rats and robots, we aim to clarify the effective factors in communication. The experimental system is equipped with a CCD camera above the experimental field. The positions of the rat and the rat-robot are calculated in real-time. We have developed the Rat-Robot WM-5 (W_aseda M_ouse-No.5). The main features of the robot consist of the similarity in figure and size, the remote control by an FM receiver, the ability to change direction on the spot by the use of a two-wheel mechanism, the shaking of the head, and the behavioral imitation of a rat's mounting. An interactive experiment between a rat and a rat-robot was carried out with the developed system. The rat's behaviors were compared in two cases. The rat-robot mounted the rat in one situation but didn't do it in another. We observed that the robot's action of mounting the rat makes the rat more interested in the robot for longer period of time, and thus the mounting of the robot by the rat occurred. As a result, the imitation of the rat's mounting seems likely to work well in the communication between rats and rat-robots
