German automation company Festo is known for taking cues from nature when designing robots. This time, it has revealed futuristic-looking bionic ants, realistic robotic butterflies and a silicone gripper based on chameleons' tongue. Just like real ants, the 3D-printed BionicANTs can cooperate in small groups to move bigger objects, though they're much, much larger at 5.3 inches in length. They have cameras on their heads, optical sensors on their bellies that enable infrared navigation, and antennae that function as wireless chargers. Those circuits running outside their bodies are functional, by the way, and not just a design to make them look cool.
