OBJECTIVE
Understand the anatomy of the hand-drawn brushstrokes
During the first phase of this exercise we were tasked with studying the essence of a paint brush stroke. This involved understanding the tool itself: the flexibility of the hair, the viscosity of the paint, and the length of a stroke before the paint is finished. We explored the relationship between the stroke and the gesture that produced it, analyzing the movement of the hand and the brush, as well as the underlying logic driving these actions. Additionally, we examined details such as the amount of paint used, the pressure applied, and the frequency of returning to reload the brush.

ROBOTIC BRUSHSTROKE TESTS
Understand the anatomy of the robotic brushstrokes
During the second phase of this exercise, we mounted a paintbrush on a small ABB robot to automate a movement and create brushstrokes on a paper canvas. The subject of the painting was the anatomy of the tool = the brush itself. This exercise focused on understanding the types of strokes the robot could produce and how its mechanical features, such as articulations, rotational axes, reach length, and overall “anatomy,” influenced its painting process. Building on our analog understanding of the human hand anatomy in executing brushstrokes, we were able to teach the robot how to replicate and develop the final paintings.
