Im working here in Metro Group (as s/w developer) and seeing this robot for over a year roaming around the campus, with her master though. As we asked the master about it, it will deliver to the person directly where he is in the designated area, in addition to home address using user mobile. And it sounds a bit so we know if its around. Im eager to see how it actually works, as there are many obstacles for here to face on the way.
