I Built a Robot to Paint Expensive Art

  • Roy Lichtenstein's was a pop art legend and his paintings have sold for millions of dollars. I thought I'd make a huge robot to replicate his style and make a million dollar painting for myself. The result was over a year of designing, programming, testing, and finaly painting a masterpiece (I hope). I call the robot Roybot.
    If you're interested in getting a print that is phyically signed and numbered by Roybot, email art@nerdtronic3d.com and ask for a price list. Prints are ready now. Limited edition only 250 will be made. Prices start at $150 and go up to $1750.
    Roybot will also be producing other artwork. If you're interested in getting an original one of a kind piece - email the same address and let me know.

    That's no forgery, that's real art. Part of what we admire in art is the skill of the artist, and the medium which you've used, digital, robotic, technical... I mean, just the fact that you had to engineer a robot and go through part iterations, the fact that you wrote software, and the fact that you made the art digitally anyways... this was insanely impressive.

    Next step is writing a software that generates the robot's path. To begin, make it so that you are able to feed a single layer of paint, and choose a stroke direction and type. The softwate will then fill that layer with lines or dots and generate a path.
    After a few iterations, the final software should be able to accept either single colored layers or any image with a set pallet of colors, and slice it up.

    • @Nerdtronic
      @Nerdtronic  Před rokem +21

      Maybe. I think part of the art part of it is designing the toolpath so that it looks like paint strokes and not all vertical lines. Thanks for the suggestion and thanks for watching.

    • @HenryLoenwind
      @HenryLoenwind Před rokem

      I'd think a useful first iteration would be to detect outlines, convert those into tool lines and then remove that area from the input. Rinse and repeat. As a second step, remembering the ends of paths and then trying to align the starts of paths of the next iteration with those, so the pen does not need to be lifted by can just move over one stroke width, might be nice. This kind of paint looks like it can take a bit of double-covering without it showing up.

      @@HenryLoenwind Seeing the paint strokes is part of the attraction (or you can otherwise just order a big digital screen printing on vinyl). At least, if that is your taste.

Each their own I'd say.

    So, a few comments, observations:
    A. This is amazing, and you are amazing. I love it.
    B. You basically built a vertical 3D printer, but without the extruder and heating elements, and with custom motors?
    As such, I probably would have went the route of trying to make it work with conventional 3D printer software. Imagine if you used Klipper, configured the stops of the new motors, and set up the "pen in/out" mechanism to work with the extruder code.
    Then, all you'd have to do to create this kind of art is split your image into multiple layers with the shapes to print, then feed the flat image into some kind of CAD software to extrude it into a one-layer shape that you drop into a slicer and print.
    It would save you a ton of time having to manually create all the paths in illustrator, as well as have saved you the headaches of trying to get the paths to trace right.
    Still an incredible teaching video and overall process...but if you wanted to supercharge it and make it easier to make more art - this could be how. ;)

    Above all I'm amazed you got the funds to do this. I've been doing DIY plotters since 2018 but I never got around to amassing the funds to build anything bigger than A0. When people started copying my artworks via instagram I had to close down all of my social media as those copycats without any talent were better at selling than me. It's been over half a year since I quit making plotter artworks but started working on a new project two weeks ago and I gotta say, the itch is still there.
    It was nice seeing your explorations, I came across many of the same issues, such as the pen ink feeds, and drilling them out which works really well. I work with high-flow acrylic inks which are a lot harder to control (drilling the caps means they tend to leak all over the place), but they have a nice fast flow if you're into speed. That's the main thing where our machines differ, mine are super fast and have zero backlash, but they can't go bigger than A0 and I didn't have the funds to get decent extrusions, so the frame is quite vulnerable.
    I'm currently working on a special design to minimize some motion artifacts and I think that's probably the most important step for you as well if you want to go faster. I'm also 100% sure that the backlash is coming from the inside of your motors. I know you got sponsored for the motors, but I really want to suggest using stepper or servo motors. Trust me, 0.9 degree per step motors are fine, you could even use a belt to increase the resolution further. And if you use closed loop motors you can do anything you want without complex movement planning. It looked as if you were using a Duet board, I'm not sure but it looked like that. If you are, that's great because Duet has expansion boards with which you can run closed loop stepper motors without problems.
    Anyway, a joy to watch your video, and it's good you also show your failures. I tried to get some sponsoring from pen companies etc with my 2k follower instagram back in the days and I managed to get was €100 worth of pens. I am very grateful with this but realistically it's not enough to sustain this on the long term. Do you have any advice for me how I can get better sponsorship deals with companies? Do they care more about exposure or are they also in a way showing goodwill when it comes to helping out artists that are not able to fund their practice even though they make unique quality projects with what little they have?

    The machine was off by 2 mm, but hey - at least you had a resolution of 0.18 µm. 😂 Sounds like maybe the actuator was not completely necessary and a simple stepper would have done fine as well. Anyway - great work overall, and yes, I am impressed - thanks for sharing! I would recommend you use linear magnetic encoders for position feedback. That stuff is similar to what is used in digital calipers and is available relatively cheap even for huge machines like yours (well, at least the chinese stuff). Needs some skills to implement, but there's no doubt YOU can. Precision is 5 µm - so still way more than enough for drawings.🙂 But of course this would not prevent the head from sagging...

    • @Nerdtronic
      @Nerdtronic  Před rokem +1

      Thanks for the comments. The motors have the encoders built in. So I can just ask them what position they're in and they send that info back.

    • @3dbits_art
      @3dbits_art Před rokem +3

      ​@@Nerdtronic Thanks for the answer, but sorry - there's a misunderstanding. Don't get me wrong: The Roybot including the software is a master piece and you can be very proud of it. And the actuators are fantastic devices - there is absolutely no doubt! But the built in encoder has absolutely NO clue of the head position. It ONLY knows about the motor itself. But the motor is just one part of the positioning system. The complete belt system including the pulleys plays a much bigger role. A linear magnetic encoder would completely remove issues due to belt and pulley accuracy, belt tension, including change of belt tension over time, plus backlash and even some issues due to temperature changes over such long periods of continous use. An alternative would be a refernce point to check (for example using a hall sensor) every know and then. But relying on a belt + pulley for accuracy is just not working well (as you have seen).

    • @Nerdtronic
      @Nerdtronic  Před rokem

      I see. Well assuming that nothing slips the motor returns an absolute position in the form of a multi-rotation angle, which simple math turns it into a position on the wall in mm (execpt for backlash). I said as long as nothing slips. Once when toward the end of the black pass I made a mistake and had the pen mech down when it was off canvas, then put a pen in and told it to draw something without raising the pen first. It was going to crash the pen into the side of the canvas. I went to quickly unscrew the thumbscrew and take the pen out and in trying to prevent it from ripping the paintng off the wall I caused the motor to slip in the gear and then the registration was lost. I was able to recalibrate it close enough to continue.
      I think the backlash will go away if I tension the belt tighter. But I'm also going to make a gear rack and try that.

    • @3dbits_art
      @3dbits_art Před rokem +1

      @@Nerdtronic Thanks for the detailed insight. Well, accidents like those just happen.
      What I was trying to say is that even with perfect rotary encoder feedback and perfect calculation there will always be a delta between the computed and the real position. This could be eliminated by linear encoders. But I don't want to bother you with that any longer.
      One additional idea: Maybe you can compensate at least belt (tension) issues by using two reference points on each axis - one near each end. You can then measure the motor steps in between. The value should in theory always be the same, but over time it will not be the same in practice.
      I think higher belt tension might lower but never eliminate backlash. But maybe you can get it low enough for the purpose (i.e. to maybe 20% of the pen stroke width).

I wonder if you could do something similar only using the paint pens or permanent markers instead of string. I mean the whole point of using the string on a small scale is to create a straight line, but using your robot it would be easy to create a straight line with a pen. I’ve seen another YTr try to recreate string are using a CNC machine like yours, but all I could think is “why is he using string? Much easy to use a pen?”.

    To be fair, Roy Lichtenstein stole all of his famous painting from comic artists so even if you had copied one of his paintings it would have probably been totally fair.
    There's blogs online documenting all of the instances of stolen art. The idea that he somehow "elevated" the art by printing it on a canvas is insulting to the artists who originally created these works. Look up "drowning girl" to see how badly he copies and comes out looking like the less talented artist.
