Can a precision articulated robot draw random?

The experiment focuses on the topic of accumulated imprecision in robotics, and rather than attempting to compensate / control the inherent imprecision in the system, the iterative photography process record, accumulate and amplify the imprecision with each pass.

The CAD path given to the robot starts with a simple straight line, circle, or triangle. The actual path drawn by the robot, with its small imperfections, is faithfully tracked and becomes the next CAD path given to the robot. overtime and over multiple iterations, the small imprecisions gradually accumulate.

The robot therefore draws its own inprecision.
