A Review of Robotic Drawing

Drawing robots are designed to copy or create drawings without human's help. Based on the number of colors in their works, drawing robots are divided into mono-color drawing robot and multi-color drawing robot. In this article, we begin with the current situation of two types of robotic drawing. Then we put emphasis on the research areas of robotic drawing and do some research on relevant technology challenges which including image processing and style transfer. Among these research areas, image processing provides a way to compare aimed drawing/color with current drawing/color, to define whether the drawing is finished or not; style transfer gives a method for robots to create new paintings by combining the content with style of different pictures. We have an overview of these key technologies and point out the problems in current methods. Then we come up with a result that the future trends of robotic drawing is becoming faster, more humanized and more creative.
