CIA has a fun toy to spies on their target called Insectohopter. It shaped in to imitate a dragonfly, and it’s carrying a tiny listening devices for surveillance purpose. Take a look at the following picture:
This Insectohopter is found on CIA museum. It looks like a promising spy gadget, but sadly it never has the change to show off its capability…
The reason is due to the miniature of Dragonfly is too light, impossible to make it fly high or even a gentle wind breezes will send it out of control. Unless they can pre-program the Insectohopter with a kind of “auto balancing” mode when the wind blows, this dragonfly is destined to stay in the museum forever.
