PRO (Painting Robots Orchestra) is a swarm of robots that react to sound. Each robot is sensible to a distinct frequency. When the robot hears some sound, music or actually any sound, from its frequency it makes a line. Since the 5 robots cover all the frequencies, the resulting paintings are a kind of graphic register of the sounds produced.
PRO performed several times at concerts by OCP (Portuguese Chamber Orchestra) at CCB (Belem Cultural Center), Lisbon.
