This paper, Robotic Arm: Extension of Artistic Actions, addresses the transformative role that advanced technologies play in the realm of artistic creation, exploring their implications for the expressiveness of works of art in the making. With robotic systems used in artistic expression, key concerns arise regarding the authenticity of the artworks produced in this way and the validity of the use of such technologies in artistic endeavors. Key questions are raised: do these robotic entities function merely as sophisticated tools within the framework of creative expression, or do they establish a new form of artistic authorship independent of human influence? This research stimulates a debate about whether robot-assisted artworks can be considered creations of machines themselves, or whether the essence of human activity continues to underpin artistic expression. Through the examination of contemporary artistic practices and technological innovations, this paper seeks to illuminate the dynamic relationship between human creativity and the use of robots in art. It critically examines the role of robotics as a facilitator or co-creator in artistic production, exploring whether such technologies are fundamentally transformative tools or simply augment traditional methodologies of artistic expression. In doing so, this study aims to contribute to the broader discourse surrounding the impact of technology on art, clarifying the emerging relationships in contemporary artistic practices: new technology – art – artist.
