Talcum powder print bot

It’s been a while since we’ve seen a new print bot idea. [Kyle] sent in his groups final project at Georgia Tech. An ever so handy iRobot chassis, a dot matrix printer carriage and motorized drill bit in a funnel strategically dispenses talcum powder to print messages or images on the floor. Just think, one robot can write all over the floor and the other one can clean up afterward. How long until some sports geeks build a bigger one to deface a football before a big game?
