We love Festo's creations. The most recent addition to their family of soft, flexible, nature-inspired robots is the SmartBird. As shown in the video below, at first sight, the robot looks like a regular sea gull (albeit a silver one).

This autonomous ornithopter emulates the shape and flying technique of a sea gull. Its silent natural-looking flight could make it a very good spy UAV. See the video below in order to know more about the robot's mechanics.
