Merry Christmas from our new robot overlords! Okay, this adorable little quadrocopter won’t be taking over the world anytime soon, but it certainly does command attention when it hovers above a keyboard and hammers out a jaunty little “Jingle Bells” tune with its protruding foot.

The bot is called Echo and it was brought to life by the Swiss Federal Institute of Technology’s Institute for Dynamic Systems and Control (or SFWITIDSC if you’re feeling cheeky). It and other quadrocopters are used to study the high-performance flight capabilities of agile little robots. As the end of the video shows, putting together this little ditty was a slightly dangerous task (for the robots, at least) – so don’t ever say they never did anything for you.
