000000bot is at it again

8 04 2010

Got most of the kinks worked out, we’re picking and placing paper now using the second robot – apparently this is MUCH harder than we imagined…I now have a lot of respect for those in the paper feeding/printing industry.

Here’s a quick video of 000000bot drawing a tag that was uploaded by the graffiti artist TEMPTONE to using the eyewriter.

Next up –> iPad!


Paper is porous? Who’da thunk…

Using the second 6-axis robot to move paper in and out of the ‘graffiti pad’ in proving much more difficult than we thought…We are using 4 suction cups pulling ~10psi of vacuum to grip the paper, and instead of picking up one sheet at a time we’re lifting the whole stack!  The solution? – Use photo paper because it’s much less porous!  I probably should have thought of this before buying 500 sheets of 110lb cardstock.

Those of you familiar with Graffiti Analysis will recognize the tag below (it’s the logo)…drawn by our very own delinquent robot!

If anyone has a tag they’d like to see drawn by a robot, send a link to the GML code from to –> (those are zero’s)

Graffiti tagging robots!

5 04 2010

Every once in a while I get to do something really fun at work.  For the last few weeks I’ve been working on a project to take data generated by Graffiti Analysis (iphone app) and make a robot draw the tag.  Graffiti Analysis is a really cool app that lets you draw quick graffiti tags and then upload them to, a repository of GML (Graffiti Markup Language) code.

The final demo will include an iPad, 1 more 6-axis robot, and lots and lots of paper and smelly markers…until then, here’s a video of a low-speed trial run…and yes, it does look like a 4 year old drew that picture 😉

How it works:

  1. Draw graffiti using the Graffiti Analysis iPhone app
  2. Upload to from the app
  3. Our pc application automatically downloads new tags from 000000book that came from a specific user
  4. The pc application translates gml code into real world robot coordinates and sends the data to our robot controller
  5. The result: a really expensive automated graffiti tagging machine!
