| Historical note on the evolution of drawbots: Nike's Chalkbot was a direct and uncredited steal of IAA's Graffiti Writer robot project/ Streetwriter truck: from political dissent to branded drivel in one smooth move. The OP's Chalkbot however announces itself as being inspired by Jurg Lehni's HEKTOR (2002). Scholars (HT @Sandy Noble of Polargraph) will note HEKTOR's twin-cord design from 2.30m in this deeply awesome MIT MediaLab/ SIGGRAPH video from 1988. Made of Lego! Programmed in LOGO! Presume there are antecedents (pendulographs, anyone?) for this too. AFAICS, Lehni does not acknowledge the MIT crew anywhere... tsk tsk.
