The First Spherical UAV Flying Machine

This little RC flying machine is getting some big attention here lately. It is pretty impressive how it mixes such stable vertical flying with a rapid transition to a more normal horizontal flight. This UAV was developed by the Research Department at Japan's Ministry of Defense. The addition of gyros coupled to the servos gives some added position stability, and the round shape does give it a rather unique option to roll along the ground. They claimed a total cost of the parts of $1,400 to build it, amazing!
