RoboRaven
[ame=http://www.youtube.com/watch?v=mjOWpwbnmTw]Robo Raven (UMD Robotics) - YouTube[/ame]Researchers at the University of Maryland, funded by the U.S. Army, may have just taken drone warfare to the next level.
The Robo-Raven is a robotic bird, with wings that can flap independently of one another. This technology makes the aircraft appear like a live bird.
In fact, a YouTube video from the University of Maryland Robotics Department shows the Robo-Raven in flight, a flight so lifelike that the machine gets attacked by a hawk at 1:49 in the video.
