Raspberry Pi based Robot for Drawing Patterns on Ovoid Objects

This paper proposes a Raspberry Pi based embedded system, consisting of a 3D printed custom frame, stepper motors, servomotor and robotic arm, which can be controlled using an intuitive Python graphical interface in order to draw precise patterns on ovoid objects. This robot is able to assist humans in their artistic behavior, by performing accurate drawing tasks with the aid of automation. For the proof of concept, we define 3 models, with various levels of complexity, which are automatically drawn on an egg-shaped object. The proposed drawbot solution proves to be cost-effective, reliable and precise.
