Portrait Painter

Hello, I wanted to tell you that this project is participating in this contest: https://robotart.org/team/profile/portrait-painter-robot-project/ and I wanted to ask you if you can vote for my portraits. You can vote through Facebook. I have sent 4 portraits and you have to vote individually and you can give up to 3 votes each. In this concussion I am competing with universities and even with the M.I.T. Beyond winning, being in this type of events helps my project a lot, so if you can give it a little diffusion it would be fantastic. In the attached image are the four portraits sent. In the link you can see a little the history of each one and a video of its execution. Share it with everyone you want. Thank you very much. Vote for me !!!!

I upload this video to show the new version of the robot. Now  have four brushes of different size and

can select them automatically to paint brushstrokes of different thickness

I'm very happy and exited

I have built a prototype to test the algorithms and I have done this test.

Why HSB color mode?
We are accustomed to using the RGB color model to define the color of our applications and it is unusual to hear about the HSB color mode.

This mode allows us to define a color using the physical parameters that define any color.
"H" is the color in itself, without any alteration. "S" is the saturation, ie the purity of the color. And "B" is the brightness, that is if it is lighter or darker.

IF we take any color, and we express it in its RGB components, for example: R = 115, G = 75, B = 187, and then we take red, green and blue oil painting and mix quantities proportional to those values and We mix, we will not get by any chance the desired color.
The reason is that the RGB color mode is based on the additive synthesis (mixture of lights), while when we want to achieve a certain color by mixing pigments, we use subtractive synthesis.
In the "FILES" section, you will find a file called "proccess.pdf", where I try to explain how to use the HSB color mode to obtain the necessary information for pigment mixing.
