Ann, although all of the devices are marvelous, I too was taken by the two helium-filled lighter-than-air devices. I would expect very long flight times for these, as power is only used for control and accelleration, and not in keeping the craft airborne. Very stealthy sound-wise also....
Ann, I really enjoy your robot stories. The AirBurr looks strange but is really cool robot. I especially like it can stand its self back up and return to flight without human intervention, even though I can't visualize how it can accomplish this. I would have loved to seem that in action.
I've seen several videos of the U of PA robots. I love them playing music.
It is interesting too see the items that were based on hobbies. My son has an Airhogs RC copter that actually takes downloadable video. At $60 retail, this is great miniatuarization as well as great cost reduction to make the product affordable. On the slideshow, the Air Penguin is pretty neat. Great article.
Thanks for your insightful (as usual) comments, Ivan. The small size and amazing abilities of some of the tiniest robot flyers are impressive, and couldn't be done without much smaller, more efficient and more powerful components, including the ones you mention. Cameras and silicon are kind of obvious in the shrinking component department, but controllers and motors have taken longer to get miniaturized. Regarding the fun element, I found it interesting that at least one of these, MIT's Phoenix, originally started as a redesigned hobbyist craft. I wonder how many others began in a similar way?
I think the key to a lot of this interesting work is the miniaturization that has happened in control systems and powertrains. The smaller cameras and radio devices make this technology quite useful. More applications will develop as the technology progresses. 6 axis motion control, location and obstacle sensors coupled with computer controls and data relays will find many many applications.
Each of these machines might find a different application based on specific requirements. Some will need to go fast, some carry loads, some perform reconnaissance and others might be just for fun.
My personal favorites are the Festo machines, especially AirPenguin and AirJelly, just because they seem so improbable, as well as being beautifully designed. But the part of me that comes from my ME grandpa is fascinated by the miniature swarming helicopters.
@Ann: Thanks for this. The image of the flying penguins was particularly cool.
Usually, when engineers look to the natural world for inspiration, they look to the animal kingdom. But plants actually provide many examples of mechanical motion, too; to convince yourself of this, just watch how flowers open and close, or how a grapevine climbs up a trellis, or (as an extreme example) how a Venus flytrap catches a bug. A recent book describes a number of plant-inspired aerial technologies, including an electrochemical actuator to control the twist of a helicopter blade.
Wal-Mart will hold its second Made in the USA Open Call July 7-8, at its headquarters in Bentonville, Ark. The event will be a repeat effort by the world’s biggest seller of consumer goods to increase the amount of US-made products it sells in Wal-Mart stores, in Sam’s Club members-only wholesale outlets, and on walmart.com.
From design feasibility, to development, to production, having the right information to make good decisions can ultimately keep a product from failing validation. The key is highly focused information that doesn’t come from conventional, statistics-based tests but from accelerated stress testing.
There’s a good chance that a few of the things mentioned here won't fully come to fruition in 2015 but rather much later down the line. However, as Malcolm X once said, "The future belongs to those who prepare for it today."
