Robo Raven

Alex Knapp admires it:

Professor S.K. Gupta has been working on creating a robotic bird for over 8 years now, and other engineering groups across the world have also been working on robotic birds. And while the RoboRaven isn’t the first robotic bird to take flight, it is the first robotic bird to have two independently functioning wings. That gives it a huge advantage in flight, since the independent operation gives it more aerodynamic configurations and more practical applications.
