HANGING PLOTTER WITH A color twist

[Jack Boland], a mechanical engineer at the university of Wisconsin, developed a great hanging plotter job called HangBot. It’s a relatively common setup, where he converts an picture to G-Code files, as well as it is plotted utilizing two stepper motors for control. We’ve seen vertical plotters before, however they tend to only have a single pen. [Jack] broadened this to bring color into the mix by splitting an picture into separate CMYK layers, as well as plotting each onto separate transparency film. When overlaid, they produce something close to a full color image. His concept is to utilize this configuration as a replacement for typical window signage.

Since it’s drawing a constant line, he appears to be employing a grid instead of a traditional dot pattern. That, integrated with the inaccuracy of a marker tip means resolution will be limited. Still, you can tell that he’s made a excellent begin in this (albeit blurry) photo. inspect out the video of it’s operation after the break.
