You never know what you're going to encounter at the airport, but chances are no one is expecting a Christmas carol-singing robot. That's exactly what you'll find at Scotland's Glasgow Airport.

The robot, named GLAdys, is an airport ambassador. Instead of training the robot to answer questions or stay in one place like a help desk, airport officials have GLAdys roam the terminal with the intention of entertaining guests.

According to the Glasgow Airport, the robot will do a number of things with travelers. Not only will GLAdys sing three different holiday songs—“Santa Claus is Coming to Town,” “Rocking around the Christmas Tree,” and “Rudolph the Red Nosed Reindeer”—it will also feature a mounted camera where travelers can take photos with the robot ambassador and send the image to themselves.

The best feature may be GLAdys' storytelling: You can also ask the robot to tell three seasonal tales: “Twas the Night before Christmas,” “When Santa Claus Comes,” and “Santa’s Workshop.”

This isn't the first time the airport has used technology to delight flyers.
