    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

    ABSTRACT: We introduce a trial to realize interaction between a rat and rat-robots in advance of communication between human and robot. The rat-robots were developed, and it is our intention to gain information on useful elements in interaction by repeating behavioral experiments. Similarity of figure and size, the ability to change direction on the spot by use of a two-wheel mechanism, and remote control by FM receiver are the main features of the robot. The experimental system is equipped with a color CCD camera above the experimental field, using this the system captures and processes images of the rat and the rat robots in real-time. A rat weight control system by network is attached to the experimental system for the purpose of reducing experimental work. This system is operated with a Java applet on an Internet browser, so that the installation of an exclusive application is unnecessary. In this way, experimenters can control machines from anywhere by using an Internet browser. When experiments were performed in which the rat-robot guides the rat to the food, we observed that the rat ran after the rat-robot. As a result, it was confirmed that it is possible for a rat-robot to guide a rat

    ABSTRACT: In this paper, we introduce a trial to realize interaction between creatures and robots. As the first step, rats were selected as an experimental target as a simplified form of interaction between human and humanoid robots. A rat robot was developed. Infrared transmitter, similar outlook of rat's figure and size, front-wheel steering and rear-wheel driving mechanism were equipped to the robot as the main features of the robot. An experiment system was developed to enable interaction between the rat robot and rats. The experiment system is equipped with a color CCD camera which captures and processes images of the rat and the rat robot in real-time. Behavioral experiments were performed with the system. As a result, it was confirmed that behaviors of the rat robot influence the rat's behaviors
