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.

The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team 100 to make (about $161 US).
At Medical Design & Manufacturing Midwest, Joe Wascow told Design News how Optimal Design prototyped a machine that captures the wing-beat of a duck.
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
