QB is a telepresence robot, the goal is to transport your presence to somewhere else. The best way to do this is by creating an "avatar", which is a symbol for someone being remotely present. When you get closer to it, you can see exactly who is being represented by this avatar. If you think of it from the social robotics and symbolic interactionism (sociology) point of view, it is one of the most beautiful TPR solutions out there to date. Hope that helps illuminate your question! :)
