An explanation via TechCrunch: “Nithin Mathews, Anders Lyhne Christensen, Rehan O’Grady, and Marco Dorigo are researchers from Universite Libre de Bruxelles and Instituto Universitario de Lisboa and they are leading us down the primrose path towards human extinction. More precisely, they’re using a method called specially-targetted communication. The flying robot “selects” ground robots and communicates with them by changing LED colors. Once the airborne robot sends the right signals to the ground robots, they can work together to move over and around obstacles that the ground robots cannot see.”
