pneumatic control

It is difficult to control motion with precision using pneumatics.  How was mid stroke position control done?  How about "stiffness' of position?  I would have though that hydralics or servo motor would have been better.

Chuck, glad you liked the story. There wasn't a lot of technical detail, but it may be available on the website at the link I gave:
http://www.festo.com/cms/en_corp/12713.htm
perhaps in the brochure, or in the components descriptions found elsewhere on the site. Let us know if you find out.

Rob, based on what I've seen that DARPA and other military agencies are doing in robotics R&D, I wouldn't be surprised if that already exists, at least on paper.

It probably does, Ann. Technologically, it would simply be an extension of the hand. Add a stealth component to it and you really got something.

OLD_CURMUDGEON, thanks for your real-world input on the company's  components. It's also worth noting that, aside from their products, another main focus for the company is their Bionic Learning Network, which is biomimicry R&D in cooperation with universities and other research entities.

You're very correct in your observation about controlling pneumatic actuators midspan.  I have accomplished this with a fair degree of accuracy both in the vertical plane & the horizontal plane.  It's NOT easy, but with powerful processors & some due diligence, it can be done.  At least I've done it with several designs, which have been working well for several years without any creep or change due to wearing components.

Excellent article and a fascinating subject.  I work in an industry in which carpal-tunnel syndrome seems to be the norm and not the exception.  I have friends who have undergone surgery to repair tendons damaged from the syndrome and some have told me there were times when the pain was so great they considered amputation.  (I know that's hard to believe but there were more than a few.)  This device could possibly provide some method to mitigate (and alleviate) pain associated with repetitive movement during assembly processes.  I feel the overall concept is excellent and definitely worth pursuing.  Festo has always been on the cutting edge relative to pneumatics so maybe they really have something here.

TJ, You're right about the diversity of the applications that might not have commercial appeal. Although the smart bird, for example, reminds me of technology that might be used at Disney. Big market for motion control solutions in theme parks and entertainment venues

Bob, I do agree with you that the Festo hand could be used in the application of alleviting carpal-tunnel syndrome in manufacturing. I can remember the number of carpal-tunnel cases announced weekly when I worked as a Plant Electrical Enginner for GM Auto plant in Ypsilanti,MI in the late 1980s. The material in the article was excellent.

bobjengr, I've had friends and associates who've suffered from carpal tunnel and while none have made that dramatic a statement, I can believe the level of your friends' agony. The ExoHand is designed to make those repetitive tasks easier (or even possible) and to prevent conditions like carpal tunnel from developing in the first place.

It's been two years since the Mac Mini's last appearance on iFixit's teardown table, but a newly revised version joins Apple's lineup this week.
More often than not, with the purchase of a sports car comes the sacrifice of any sort of utility. In other words, you can forget about a large trunk, extra seats for the kids, and more importantly driving in snowy (or inclement) weather. But what if there was a vehicle that offered the best of both worlds; great handling and practicality?
Kevin Gautier of Formlabs describes the making of a carbon fiber mold for an intake manifold, using a $3,300 3D printer, during Medical Design & Manufacturing Midwest.
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
