In January 2010 I wrote about an amazing radio controlled four rotor helicopter known known as the Parrot AR.Drone, which utilised the iPhone gyroscope, touch screen and built in wifi to produce the most amazing flying toy I’d seen at the time.

Two years have passed and now the GRASP Lab at the University of Pennsylvania with development by KMel Robotics have miniturised the same basic concept to produce nano quadrotor helicopters.

As you’ll see in the video, a lot has changed and they possess some amazing built in technology, such as being able to right themselves when thrown into the air, along with clever algorithms to control moving between obstacles, flying in formation and much more.

I think this is absolutely mind blowing, least of which because they’d make an amazing toy but mainly because it represents a huge leap forward in robots and sensing, a lot like the self driving cars that Google have developed.

Amazing.
