A prototype robot spy hummingbird was shown on a video performing flight trials in California. Made for the US military by AeroViromnent Inc., this little guy flys around, and hovers just like areal humming bird. Teh wings flap quickly, and they must have studied these little guys for a while, as it changes direction, like rudders on a plane, and it can go forward, back, up or down.
And there is a little camea mounted on it that records video. Here is a YouTube video. We liked this one the best, though just search for nano helicoptor for the rest. This shows it close up hovering.
This is totally cool, and let me know when you get the fly spy bot ready, as I like to snatch them out of the air with my 6 inch tongue.
