JAMES (Joint Action for Multimodal Embodied Social Systems) is a robotic bartender that not only serves drinks, he serves up jokes. At about a meter tall, he only has one working arm and is programmed to serve customers in order. We dug up his first demo that was done in November 2011 by his creators Manuel Giuliani and the Munich Research and Transfer Institute for Software-Intensive Systems.
This second video was made in May 2012. He seems to have improved but only in skills. (He still looks and sounds similar.) We are not sure if he can yet distinguish between the bottles he picks up or just grabs them in order. Either way, he is clearly a service bot in progress.
