This paper explores the intersection of artificial intelligence (AI) and creative expression through the development of a real-time interactive painting robot designed to accompany live musical performances. Using a robotic arm controlled by audio inputs processed through Max/MSP and communicated via Open Sound Control (OSC) messages, the system generates visual art that responds dynamically to music. This collaboration between human musicians and AI challenges traditional notions of creativity, authorship, and control, raising questions about the role of machines in the creative process. By analyzing the outcomes of various performance iterations, we examine the ambiguity in creative agency and the potential for AI to redefine artistic boundaries, offering insights into the evolving relationship between human and machine in the arts.
