This piece is a joint performance created by Infonaut and Quartet.cc. Quartet is an Internet Interactive Kenetic Musical robotinstrument.
The interactive music robot was developed by art roboticists Jeff Lieberman and Dan Paluska and consists of three robotic musical instruments and an installation visitor. The division of labor is simple: the user inputs a musical motif, software composes a work, and the robot orchestra delivers the performance (though one that turns out to be a highly complex affair). The five-centimeter-wide bars of a marimba are bombarded with balls fired from several meters away, robot fingers dexterously draw melodies out of a wine-glass organ, and an unconventional percussion section provides the rhythm.
The musicrobot Quartet is hosted by the Ars Electronics Center (AEC) in Linz Austria, where visitors can create their own song live, which will automatically posted to YouTube. The music robot can even be accessed via Internet.
