Khepera swarm robots learn to build a mobile quadrocopter landing platform (video)

Last we saw the Khepera swarm robots from the Georgia Robotics and Intelligent Systems lab, they were just beginning to learn how move in formation and spell out "GRITS" on the floor. Well, these bots are growing up fast. The lab's latest video shows a group of four of the robots following a leader, and arranging themselves to form a mobile landing platform for a hovering quadrocopter -- a feat they manage to make seem easy. What will they think of next? We're a little scared to ask.
