The Obsessive Drafter (TOD) is an interactive robotic art installation that seamlessly blends engineering with artistic expression. Though not fully sentient, TOD aspires to be an artist in its own right, embracing imperfections and unpredictability in its creative process. This 3.5-degree-of-freedom robot mimics the shoulder and elbow movements of a human artist as it glides along a wall on motorized wheels, leaving behind unique portraits of those who pass before it.
At its core, TOD is constructed from a lightweight metal frame connected by custom 3D-printed components, blending robust engineering with adaptable design. Its low-level controls manage fundamental tasks like movement and sensing, while a single-board computer connected to a webcam handles high-level processing. TOD’s visual pathway tracks passersby, isolates one individual, captures their image, and processes it into abstract patterns of lines. As a robotic art installation, it translates these inputs into stylized sketches, adding an element of artistic abstraction to each creation.
The interaction doesn’t end there. When TOD finishes a portrait, it roams back and forth, scanning its surroundings for the next subject, ensuring a dynamic and ever-evolving artistic display. Each wall it draws on can accommodate multiple portraits, depending on the venue size, creating a shared space of creativity and curiosity for viewers. This robotic art installation thrives on unpredictability, offering a unique experience with every portrait.
Since its debut, TOD has captivated audiences at prestigious events such as Design Days Dubai (2014, UAE), exhibitions in Beirut, Lebanon, and the IEEE International Conference on Robotics and Automation (ICRA) 2019 in Montreal, Canada. Its unique incorporation of disciplines like 3D printing, mechatronics, and algorithmic design has drawn interest and curiosity about the potential role of machines in creative fields.
TOD was conceived by Guillaume Crédoz, Nareg Karaoghlanian, and Chady Karlitch. Over the years, it has been showcased at numerous events spanning four countries and three continents.
