Fully Autonomous Flapping-wing MAV Is As Light As 4 Sheets of A4 Paper

Unknown Lamer posted about 9 months ago | from the paper-airplane-2.0 dept.

Robotics 79

Hallie Siegel writes "According to its developers, the DelFly Explorer is the first flapping wing Micro Air Vehicle (MAV) that is able to fly with complete autonomy in unknown environments. Weighing just 20 grams and with a wingspan of 28cm, it is equipped with an onboard stereo vision system. The DelFly Explorer can perform an autonomous take-off, keep its height, and avoid obstacles for as long as its battery lasts (~9 minutes). All sensing and processing is performed on board, so no human or offboard computer is in the loop."

Um, are you sure? If by "room" you mean surface area, A4 paper is slightly larger than letter.

A4 = 210 x 297 mm = 62,370 mm^2
Letter = 215.9 x 279 mm = 60,322 mm^2 (rounded to nearest mm^2)

Back in old times, when we were behind Iron Curtain and in few years afterwards, Pen&Paper RPG books were precious commodity. Imagine having to spend half a month salary for a single book. So 'secondary' market was thriving, with somebody buying a book and then everybody else photocopying it over and over. Unfortunately, photocopiers were A4, while most RPG books were in letter format, which was causing ugly black borders on top and bottom and angry stares from the shop owner, who was using a lot more toner than he has expected...

Good point. A4 is only a dimensional size, nothing to do with actual mass or weight. Are we talking about the kind of paper they print phone books on? Or is it a heavy card stock or bristol board which isn't too far removed from being considered cardboard instead of paper?

An unladen honeybee is about 80mg.

Also compare with the smallest bird in the world: https://en.wikipedia.org/wiki/Bee_Hummingbird [wikipedia.org]

But it looks like it's only going to work indoors, with all fans off. Being that there's no way to control it, seems like it'd be less than entertaining, other than to present to an unsuspecting audience, like slashdot.

If you think that's lame, I heard that some idiot bike mechanic brothers demonstrated a so-called flying machine that could barely get 10 feet off the ground and couldn't even stay in the air for 60 seconds. What a joke! It's clear that it's doomed to fail since the early prototype was so limited.

Why are you modded insightful?

the idiot bike mechanic didn't demonstrate their flying machine for 3 years so they could work the bugs out of it. When they finally did demonstrate to the public a flying machine it took off from a level surface flew around the field a couple of times and landed where it started from. Then they started taking passengers up.

Now a days their first flight would have ben hailed, scrutinized and when they didn't deliver a fully functional fighter jet 6 months later ridiculed.

Just because it has to fly indoors today doesn't mean that it couldn't some day be constructed to allow outdoors use. It's not like there are no "craft" [wikipedia.org] that fly outdoors with large, fragile wings.

Ooo, no fair. You're comparing a butterfly - a part of the bio-logic of Nature itself, evolved from the very fiber of the physical universe's intelligence over billions of years - to some rig that was recently"invented" by humans? Come on man. You may as well compare a lighter to our sun, or a sand castle to a mountain. I'm not trying to offend you, sir, but silly indeed.

In order for what man has come up with to achieve flight using, the basic construction of the item in question in this article, outdoor, it's going to have to learn to use the wind as the butterflies do. Man still is in awe of birds flying in a V formation, so how will he ever understand flight in this way, until he himself flies with his own apparatus, and use the wind as a part of flight?

I'm not sure how much stereo is in that vision (2)

steve.cri (2593117) | about 9 months ago | (#45716547)

Indoors stereo vision is so hard that if the DelFly actually navigated by stereo vision, this alone would be truly groundbreaking. Especially given the limited processing power on this thing. However, judging by the papers publicly available, the actual collision avoidance on the DelFly seems to rely on optical flow, and complementary, a new model of texture analysis called "appearance variation cue". Both of which do not inherently rely on stereo vision. I might be missing something from the more current papers though.
