We have deployed a robot \photographer" at several events. The robot, Lewis, navigates through the space, opportunistically taking photographs of people. We summarize the di erent types of human-robot interactions we have observed at these events, and put forth some possible explanations for the di erent behaviors. We also discuss potential models for human-robot interactions in this constrained setting.
