Graffiti goes digital and robotic (Video)

Robot grafitti
Here’s a totally unexpected application of robotics, one that we never came close to imagining: Graffiti tagging robots!

The week of January 4th, 2010 was designated GML Week celebrating Graffiti Markup Language (GML), a new XML file type designed for archiving graffiti tags. The F.A.T. (Free Art & Technology) group has been standardizing open source graffiti software packages like Graffiti Analysis, Laser Tag, Eyewriter, and others, so that they will be GML compliant.

The mission statement of the group is, “A new digital standard for tomorrow’s vandals.” It didn’t take long before the robot geeks at the CMU Stuido for Creative Inquiry and the CMU Digital Fabrication Laboratory hacked a ABB 4400 series robot to splash graffiti on the walls.

GML drawings, archived at, were converted into DXF format that was then processed using Rhino and MasterCam to create the robots motion files. The ABB4400 robot was equipped with a2” Montana Hardcore marker.
