Multi-robot cooperation for human-robot communication

This paper illustrates how robots can effectively cooperate to facilitate communication with people. We expect that communication robots will play an important role in our daily life. Although these robots can communicate with each other by radio, infrared, or other invisible means, our results show that it is important to human understanding that they are able to communicate with each other by voice and gestures as well. This lets humans know that the robots can talk with them and among themselves. Thus, humans come to regard the robots as appropriate targets for natural communication.
