It's a modest test, but it's ramping up to something much more impressive: In December, the robot is scheduled to return to the airport as a guide. Visitors will be able to ask for directions to say, the currency exchange counter, and EMIEW3 will physically lead them there. Neat! Hitachi's bot is particularly well suited to the task because of it's mobility: it can zip along at a steady 3.7MPH and even pick itself up if it falls down. Just don't ask it to take you directly to your gate -- airport security probably isn't used to clearing robots.
