Tchaibotsky is an Arduino powered piano playing robot. The motivation was to build something that could accompany pianists, whether they’re missing an arm and can’t play the melody to a song, or they want to play a duet but have no friends. As of now, its limited in range to C major songs (no flats or sharps).
