MeBot: A robotic platform for socially embodied telepresence

Telepresence refers to a set of technologies that allow users to feel present at a distant location; telerobotics is a subfield of telepresence. This paper presents the design and evaluation of a telepresence robot which allows for social expression. Our hypothesis is that a telerobot that communicates more than simply audio or video but also expressive gestures, body pose and proxemics, will allow for a more engaging and enjoyable interaction. An iterative design process of the MeBot platform is described in detail, as well as the design of supporting systems and various control interfaces. We conducted a human subject study where the effects of expressivity were measured. Our results show that a socially expressive robot was found to be more engaging and likable than a static one. It was also found that expressiveness contributes to more psychological involvement and better cooperation.
