complete robotic takeover. If not, we've got some dire news: these are not simply miniature Roombas as they may appear, but 15 so-called Khepera bots capable of spelling out GRITS (for Georgia Robotics and Intelligent Systems) to demonstrate grad student Edward Macdonald's Master's thesis for the department. The diminutive robots aren't told where to go in the letters -- instead, they determine their spots via a control algorithm, positioning themselves relative to their fellow rolling machines, so that if one is removed from the equation, they quickly reform the letter without it. Fortunately, they haven't learned to spell "KILL." Yet. Get to know your new robotic overlords a little bit better in the video after the break.
