Hummingbird-Size Wing-Flapping Drone Unveiled 108

Posted by Soulskill from the time-to-fill-your-bird-feeder-with-batteries dept.
garymortimer writes "AeroVironment, Inc. has demonstrated a tiny new drone called a 'Nano Hummingbird.' The hand-made prototype aircraft has a wingspan of 16 centimeters (6.5 inches) tip-to-tip and has a total flying weight of 19 grams (2/3 ounce), which is less than the weight of a common AA battery. This includes all the systems required for flight; batteries, motors, communications systems and video camera. The aircraft can be fitted with a removable body fairing, which is shaped to have the appearance of a real hummingbird. The aircraft is larger and heavier than an average hummingbird, but is smaller and lighter than the largest hummingbird currently found in nature."

  • It's amazing how much control they appear to have over the thing. I feel lucky when I can get my RC helicopter to go anywhere near the general direction that I want. And especially outdoors! The very slight breeze outside makes toy helicopter impossible to fly, but it seems like they have complete control.

      The largest hummingbird species are bigger and heavier than the drone, but the average of all the hummingbird species is smaller and lighter than the drone. So, while it's bigger than what a hummingbird is likely to be, it is not so big that it couldn't possibly be disguised as a hummingbird.
      • Thanks for clearing that up for me.

      • So, while it's bigger than what a hummingbird is likely to be, it is not so big that it couldn't possibly be disguised as a hummingbird.

        And in particular, there are quite a few hummingbird species of about that size, and the largest species, the appropriately named Giant Hummingbird [wikipedia.org] is significantly bigger. So "smaller than the largest hummingbird" isn't some kind of cop-out phrase where there's one such example in the Andes mountains but everywhere else it's too big to be a hummer.

        But in some places it certainly would be too big. For example in the Eastern United States, the only hummingbird is the small Ruby Throated, and seeing somethi

    But I have to wonder what the endurance is for this thing. TFA describes the requirements as:

    1. Demonstrate precision hover flight within a virtual two-meter diameter sphere for one minute.
    2. Demonstrate hover stability in a wind gust flight which required the aircraft to hover and tolerate a two-meter per second (five miles per hour) wind gust from the side, without drifting downwind more than one meter.
    3. Demonstrate a continuous hover endurance of eight minutes with no external power source.
    4. Fly and demonstrate controlled, transition flight from hover to 11 miles per hour fast forward flight and back to hover flight.
    5. Demonstrate flying from outdoors to indoors, and back outdoors through a normal-size doorway.
    6. Demonstrate flying indoors âheads-downâ(TM) where the pilot operates the aircraft only looking at the live video image stream from the aircraft, without looking at or hearing the aircraft directly.
    7. Fly the aircraft in hover and fast forward flight with bird-shaped body and bird-shaped wings.

    Based on the current crop of micro RC helicopters, I'd be surprised if this gizmo has enough battery life for more than 10-15 minutes of flight. Any real-world James Bond types out there care to chime in as to whether this is going to be sufficient to support a real-world mission?

    • Let's say that hummingbirds come in sizes (or weights) 1 to 5.
      Average sized hummingbird would then be the sum of those sizes, divided by the number of sizes available. I.e. (1+2+3+4+5)/5 = 3
      So the "average hummingbird size" would be 3, while the largest hummingbird size would be 5.

      So, if this artificial hummingbird is "larger and heavier than an average hummingbird, but is smaller and lighter than the largest hummingbird currently found in nature" - that means that it's size is somewhere between 3 and 5.

    • Different species of hummingbirds come in different sizes. An "average" hummingbird is smaller than this drone, but at least one species of hummingbirds is capable of growing larger than the drone.

      Seems pretty logical to me.

    • Excellent citation, thanks.

      Just judging from watching the video in hi-res, it's more like a helicopter with individually variable prop angles than a hummingbird - it looks like it's limited to "body straight up" flight.

      Still pretty astounding work for a prototype - but I'd be willing to bet a few dollars that something similar to this but with much more maneuverability - yaw and pitch - is on sale in department stores in maybe 5-7 years :-)

      If anyone has any more decent info on this,

      • The device actually already has yaw, as the video above shows (you can spin the craft around). As for pitch, I can't find a video, but I'm under the impression that it does have pitch control, being able to do loop-de-loops [wired.com].
        • Err, link should be this [wired.com].

        •   A helicopter can technically loop the loop, too, but that's not the same thing as full sustained pitch control like hummingbirds can do (they can fly head-down)
