This paper reports a study about system response time (SRT) in communication robots that utilize human-like social features, such as anthropomorphic appearance and conversation in natural language. Our research purpose established a design guideline for SRT in communication robots. The first experiment observed user preferences toward different SRTs in interaction with a robot. In other existing user interfaces, faster response is usually preferred. In contrast, our experimental result indicated that user preference for SRT in a communication robot is highest at one second, and user preference ratings level off at two seconds. However, a robot cannot always respond in such a short time as one or two seconds. Thus, the important question is “What should a robot do if it cannot respond quickly enough?” The second experiment tested the effectiveness of a conversational filler: behavior to notify listeners that the robot is going to respond. We used the same strategy in a communication robot to shadow system response time. Our results indicated that using a conversational filler by the robot moderated the user's impression toward a long SRT. Put it all together, we obtained a) users'; impressions toward the robot are unchanged until one second SRT, b) the robot should react within two seconds SRT, and c) use of conversational fillers are effective to let the users to wait from these two experiments.

The current paper reviews neuro-robotics studies by the author's group by which possible neuro-phenomenological accounts are explored for “symbolic” processes assumed in various aspects in human cognition. The reviews on the series of studies elucidate that many of “symbolic” computation scheme can be alternated by neuro-dynamic systems approach utilizing self-organization. It is concluded that “symbols” can be obtained just as an immanent property in the consequences of self-organization when natural interactions between the top-down intention and the bottom-up sensory-motor processes are allowed in embodied neuronal systems.

An observation in active volcano areas is very important to work out a strategy for estimation of eruptive activity and evacuation call to residents. However, it is a too dangerous task for human to observe in such areas. Therefore, we developed a tele-operated robotic observation system instead of human. In the system, Unmanned Aerial Vehicle (UAV) carries a small-sized Unmanned Ground Vehicle (UGV) in a target point autonomously, and UGV observes the target area tele-operatively. To confirm our developing system, we performed field experiments in Mt. Asama, Japan. In this paper, we report the results and the lessons learned from the experiments.

In this paper, we describe a robust and fast self position estimation technique for mobile robot in an environment where many unknown obstacles exist. The free-space observation model is the basis of the proposed technique. Although the free-space observation achieves robust self-position estimation, it has a complicated likelihood evaluation, and particles continue to spread to a direction where are no landmarks. In this research, we solve these problems with two likelihood evaluations based on the area of free space and occupied space. We evaluated the robustness and verify the validity of the proposed method by a simulation and an experiment in a real environment.
