"Lewis" the robot participated in 2 major theatrical events, one class lesson, several rehearsals and one user study involving a total of 9 actors, about 25 students, 3 directors and was seen by over 300 audience members. These initial attempts at understanding human-robot interaction lay a foundation for future study in this emerging field.

The best example today is the Roomba, a robot vacuum cleaner. The Roomba is specifically designed for the single task of vacuuming a room and, as such, its interface is more like that of a tool or appliance. There is little in the way of interaction as the Roomba works. However, as robots gradually take on more complicated everyday tasks, and those tasks require working with humans more direct and subtle ways, the study of Human-Robot Interaction(HRI) will gain more importance. The average person, without a technical understanding of computer processes or sensors, must be able to give instructions to the robot, understand feedback from it, and coordinate with a robot in a way that is natural and comfortable. There have been robots that were built for the sole purpose of interaction with humans. These robots tend to have high production value created by special effects artists such as the MIT Media Lab's collaboration with artist Stan Winston on the robot Leonardo [9]. Often big eyes and eyebrows are added to make the robot look like an animated character; they often have a \cutesy" feel, with extremely complicated and subtle articulation that is difficult to control. Some are even covered in fur. The purpose is to hide the fact that they are actually robots, and to evoke an affective response. From a task-achieving perspective these robots serve very little functional purpose. They are often immobile and present such a tricky control problem that they turn out to be more like high tech puppets with pre-scripted controllers than autonomous robots.
