The G6 is a fully autonomous Graffito machine designed and built by Michael Georgas, Damien Frost, and Ryan Donnelly over a seven month period in 2004/2005. The design met the need for an efficient way to create numerous graphical patterns at various locations on a wall. The G6 has the ability to store a sequence of up to 50 shapes to be drawn in a single run. The shapes are drawn at each location using a high-precision x-y plotter that ensures that all lines drawn are razor sharp and that any closed shapes are seamlessly finished. There is functionality in the prototype for more than one colour to be used in the pattern as well. The x-y plotting write-head of the G6 is mounted upon an extremely robust scissor lift that positions the machine at the appropriate row of the wall with pin-point accuracy through the automated calibration sequence built into the software. The lift/write-head assembly rests upon the stable chassis module, into which is incorporated a steering mechanism custom designed by DMR's electromechanical division. All of the above features ensure that each shape drawn by the G6 is consistently placed in the correct coordinate, and consistently drawn well. DMR design put the highest priority into these aspects of the G6.
