"Robo Painter" which reproduces touch of painter by NC machine with brush

Expression techniques that create subtle expressions on the canvas with delicate touch are the true values ​​of the painter, but it seems that such techniques will be reproduced on the machine "Robo Painter"Has been developed. Robo Painter is a computerized NC machine that is made with the aim of expressing fine touch by mechanically reproducing the pressure of the brush by the human painter (writing pressure).

It seems that the situation that has been said that "a fine expression by human hands can not be reproduced on machines" is changing. Based on the uploaded photos, we create and sell paintings by combining computers and people's handsInstapaintingThe development of a device "Robo Painter" which a computer records human brushwork and mechanically reproduces is proceeding.


In the following movie, Robo Painter shows how to draw a picture by reproducing the movement of a person, and you can also see how the picture is reproduced completely in the latter half of the movie .

A painter who "inputs" the touch of a brush using a pen tab made by Wacom. By using the pen tab, digitize the touch of the painter and generate data that can be handled by the computer.


And this machine "Robo Painter" can draw a picture with a brush. Basically, you can freely manipulate movement using a computerNC machine, But the point is to be able to perform three-dimensional control by adding the "Z axis" in the vertical direction to the "X · Y axis" in front and back and left and right.


As you move the brush against the canvas with the movement of the Z axis, you can see how the brush tip is bent.


The brush puts a brush on the palette and includes the paint. Whether it is a coincidence or aimed movement, I applied a brush tip to the edge of the palette and dropped an extra paint.


The head part was moved as it is, and I began to draw a picture from the other side of the screen.


The motion of the pen tab that appears to the left is transmitted to the machine as it is. It seems that latency (delay) of motion hardly occurs, as it is seen on the screen. Whether it is a servo motor that controls movement, it sounds quite "garbage".


The tree trunk and flower-like picture are drawn, and its atmosphere is like "ink painting".


Surprisingly, the movement that the painter quickly pays a brush "Pin, Pinch" is also reproduced. It was a moment to catch a glimpse of the fact that this machine has a considerably high tracking ability.


Works of ink painting style drawn in this way. It seems that small birds are being drawn by flowers blooming in young trees, but it is a truly amazing sight that this picture was drawn with a brush instead of a print.


In the latter half of the movie, scenes where the machine automatically draws the same picture are contained. A state of the machine on which white paper was set.


First of all let's include ink in the brush ... ...


I will draw trees with small movements.


Even while painting black solidly, the parts of the little birds that require subtle shading are reproduced in the same way.


Completed shortly. You can hardly tell the difference from the first by just looking at it.


This is the original work. There are subtle differences in the reproduction condition of birds and the "splash" part of the brush, although it depends on the inclusion condition of black, but its reproducibility is superb, and in principle it is "more than a human being You can also say that you are saying.


In this way, you can see that Robo Painter has a drawing ability that is unexpectedly high. It seems that the range of expression is limited because it seems that only single color can be handled at this stage, but attention will be gathered to the development of technology which can reproduce painting with "completely different" principle from "printing".
