I-Circle: a new method and system of robot auto-drawing

With the development of robotics technology, people are gradually inclined to study robots that can imitate human specific behavior, such as writing and drawing robots. At present, there is less research on drawing robots, and the method has certain limitations. This paper designs and completes an innovative drawing method: spiral line method, that is, the method of spiral line superimposing sinusoidal curve to draw. And it is named I-Circle. Compared with the traditional methods, it has the advantages of simple control and strong expressiveness. This work chooses two-dimensional translation platform as hardware system, uses MATLAB to process image and generate path, and uses path coordinate points to generate G code. Then the code is sent to the lower computer through serial port, which controls the two-dimensional translation platform, makes the pen draw automatically on paper, and designs GUI interface, so that the operation process is simple and easy. Through the experiment, we succeeded in drawing pictures, which proved its feasibility. This work can also be expanded, such as replacing the penholder with a micro-drill for sculpture. Similarly, it can be made into cake mounting machine, coffee drawing machine and so on. It can also lay out a drawing robot in a specific place to create drawings on the spot, which can be participated by users, or make the drawing method into software. It has broad application prospects.
