Drawing on walls is fine for children, but adults tend to get bored quickly with such antics. Even more so when they realize who is responsible for cleaning up afterwards. Instead, consider delegating those duties to a friendly helper by the name of Fumik, as [engineer2you] has done.
Fumik, who looks like a cute little jellyfish, can draw pictures up to 5 meters wide and 3 meters high, making for a massive canvas. Powered by an Arduino Mega 2560 outfitted with a CNC shield, a pair of stepper motors drive pulleys with toothed belts to move Fumik to various positions along the wall. Another smaller stepper motor is used to drive the pen forwards and backwards as needed. Fumik can be programmed to trace out various designs in SVG format. These must be converted to code and programmed into the Arduino, at which point Fumik can begin work, drawing on the wall with its pen.
It’s a fun build, and based on photos shared by [engineer2you,] Fumik is quite able at drawing clean and neat designs without a lot of smudging or jagged lines. As a bonus, it’s easy to swap out the pen, so multicolored designs can be drawn in multiple passes.
We’ve seen other robot drawing builds before, too, like this capable portrait artist. Video after the break.
Sure, this is the contest entry post, but you guys already posted about this project last month…

Also, there’s not a single tag in common with that last post, which is why you haven’t found it… Might want to be a bit more consistent or liberal with them.
There is also the article complaining that it should have been gcode driven:

I guess it at least has one tag in common with the original article.
I suggest to create a new tag : ‘duplicate’ for content writers to highlight this is again about an old topic.
Maybe ‘triplicate’ for this specific one.
Why are the belts twisted?
DUPE, but not the dupe of a post from last month. Dupe or a product from 1984: The Computer Colorworks Digital Paintbrush for the Apple II – Part 1

Same thing, but in reverse :)
How cool would it be is this were able to draw vertically without any belts attached, just attaching magnetically to a whiteboard. Oh wait, this exists: https://www.irobot.com/root
Nice project! But, if you ever encounter a real jellyfish in the wild you’ll soon realize they’re anything but cute.
Why don’t the eyes blink?
