Drawing system

A smart drawing system, comprising

• a drawing unit comprising a drawing instrument, wherein the drawing unit comprises a detectable component configured to be detected by one or more sensors, wherein the drawing unit is configured to move the drawing instrument along a third axis (z) between a retracted position (A) and non-retracted position (B) and wherein ink is applied to a target surface when the drawing instrument is at the non-retracted position (B), wherein the target surface extends along a first axis (x) and a second axis (y) and forms an angle with the third axis (z), and
• a memory configured to store an image,
• a sensor device configured to collect data relating to a position of the drawing unit through the one or more sensors and configured to output the data to the drawing unit when the drawing unit is moved by a user such that a drawing tip of the drawing unit facing the target surface is in contact with the target surface, and wherein the drawing unit determines when to move the drawing instrument to the non-retracted position (B) or to the retracted position (A) on the basis of the data relating to the position of the drawing unit and the image stored in the memory.
