Just wanted to share what I consider to be an amazing effort of robotics. The robotics researchers at UMD have perfected the ability to fly a self-contained robot using mechanics of real birds.I have been watching various groups over the years experimenting with similar designs that either could only flap their wings in tandem or prototypes that were attached to an external power source.
Watching other birds in the video interacting with it is truly impressive!
