Actually I think they're evolving into home entertainment centers. When I was a kid and a teen, all I wanted to do was to sit in the driver's seat and pretend to be the driver. Now, I'd much rather be in the back, reclining or sleeping or watching a DVD while cocooned from any potential dangers by 25 airbags and 12 cup holders.
@naperlou: Hotrodding the AR is tricky. Each motor has it's own microcontroller and drive circuitry. Switching to larger motors means reverse engineering the controller protocol and matching the timing, which I have heard is rather tight. As the weather gets better, I'll be more inclined to mess around with things that fly.
As for general overall design style. The tri-,quad-,hexa-copters are designed in the short-flight, agile, high-energy use arena. The drones we hear the most about in the news are long distance, energy efficient, long flight-time designs (liquid fueled) which brings the design back to aeroplane shapes.
The copter-drones have been used to look inside buildings after earthquakes and other short flight applications.
From boats to airplanes to...rocket ships? I know "rocket ships" sounds kind of 50s/60s, but that's what some of these newer car shapes make me think of. But maybe that's a continuance of the airplane cockpit look.
Re the cars, they also evolved from looking like houses on wheels (1910s and 1920s) to looking like boats, to airplanes, to. . . I actually forget what the analogy is for current vehicles. My observation about U.S. versus Japanese drones (military vs. manga) is original, but the car thing is an old one. You can really see how the first cars were like houses on wheels, with the high "walls" etc. Today, driver's seats are like airplance cockpits, and they'll get more so as we see the introduction of heads-up displays. That'll be a good thing, because it'll force drivers to actually look at the windshield, offering some hope that perhaps they'll look OUT it, too.
What an interesting observation, that US drones look like our military planes, whereas Japanese versions look like their fictional sci-fi characters. Makes total sense to me. Car styles used to reflect more of their respective cultures, too, back in the day, as did clothing, household objects and a ton of other things. Interestingly, Parrot the company is based in Paris. European design is extremely different from US design, in many different consumer products anyway as well as fashion, and some of it reminds me of modern Japanese design.
curious_device, thanks for your feedback. Good to hear from someone who's actually hacked the AR.Drone, and thanks for the confirmation of what I imagined: that it wouldn't take much to build a more powerful full-featured, multi-capable drone on top of this versatile open platform.
Artificially created metamaterials are already appearing in niche applications like electronics, communications, and defense, says a new report from Lux Research. How quickly they become mainstream depends on cost-effective manufacturing methods, which will include additive manufacturing.
SpaceX has 3D printed and successfully hot-fired a SuperDraco engine chamber made of Inconel, a high-performance superalloy, using direct metal laser sintering (DMLS). The company's first 3D-printed rocket engine part, a main oxidizer valve body for the Falcon 9 rocket, launched in January and is now qualified on all Falcon 9 flights.
Lawrence Livermore National Laboratory and MIT have 3D-printed a new class of metamaterials that are both exceptionally light and have exceptional strength and stiffness. The new metamaterials maintain a nearly constant stiffness per unit of mass density, over three orders of magnitude.
Smart composites that let the material's structural health be monitored automatically and continuously are getting closer to reality. R&D partners in an EU-sponsored project have demonstrated what they say is the first complete, miniaturized, fiber-optic sensor system entirely embedded inside a fiber-reinforced composite.
