　　They’re big, bionic copycats. Developed by German engineering company Festo, these artificial ants are about the size of a human hand, and mimic the cooperative behaviour of the real insects by making individual decisions that relate to a common goal.
　　Teamwork allows the ants to complete complex tasks they wouldn’t be able to accomplish on their own, like moving a large object as they do in this video. A stereo camera in each ant’s head helps it determine its location and identify objects that can be grabbed with grippers below its chin. Floor sensors also help the bots get a sense of their surroundings while they use a wireless network to communicate.
　　The design of the robots is also unique. Their plastic body is 3D-printed with electronic circuits overlaid on top with a machine. The ants’ six legs and grippers are made from ceramic actuators that can bend quickly and precisely using little energy while remaining compact.
