Robotic art is a genre of New Media art featuring performing robots. One example is juke_bots, a 2001 robotic performance installation piece featuring two robot arms acting as turntable disk jockeys. The robots are provided with a stack of records which they can place on the turntable and manipulate like real DJs by adjusting the speed, distortion, fragmentation, etc. while the music plays.
Here is a video of the installation:
