Georgia Tech’s Mason Bretan has built a robot that can not only play music, but is now learning how to compose its own tunes. Shimon is a four-armed, marimba-playing droid that draws upon its vast library of songs to help it write the music that it plays. The system was fed around 5,000 songs from composers such as Beethoven and Stefani Germanotta all the way through to acts like Miles Davis and The Beatles.
