Makers of semiconductors spend upward of $5 billion to build and
operate fabrication plants—known as “fabs”—that run 24 hours a day so
they can recoup their investment before the equipment becomes obsolete
in five years or so. Rows of pristine machines sit in windowless
cleanrooms, which are almost as free of humans as they are of dust.
Intel and Texas Instruments have spent decades perfecting this almost
sci-fi form of manufacturing. Now they want to show the rest of the
world how it’s done.
The chipmakers have set their sights on what
researcher IHS estimates is a $185 billion global market for gear to
automate industrial production. To capture a portion of that spending,
they’re prodding companies to bring the Internet of Things—a term that
describes a world in which physical objects are embedded with
electronics and talk to each other—into factories. “It’s moving beyond
hype and into engineers rolling up their sleeves,” says Doug Davis,
senior vice president of the IoT division at Intel, which had more than
$2 billion in sales last year. “The economic value and impact are
unquestioned.”
In the assembly line of tomorrow, industrial robots
now caged off to prevent them from accidentally injuring human workers
will move about more freely. A machine outfitted with optical and motion
sensors would be able to detect a hand that is delivering a tray of
parts and adjust its movements so as not to inflict damage.
Intel
is also working on technology to make humans less error-prone. Last
year it showed off an “intelligent” glove that uses chips to power a
simple display on the wrist. If the person wearing the glove completes
an assembly task correctly, a large green check mark appears. If not, a
red cross flashes on the screen. Conceived by Workaround, a German
startup founded by ex-BMW employees, the glove could become a useful
accessory at auto plants or electronics factories.
Autonomous
robots and bionic line workers are still years if not decades away.
Ethernet connections are only just making their way onto factory floors,
while Wi-Fi hardly has made a dent, which means most plants don’t have a
communications platform to support an Internet of Things. This is
partly by design: Hackers can’t penetrate systems that aren’t connected
to the outside. “The best way to protect your system is to disconnect it
from the rest of the world,” says Avner Goren, who heads embedded
processing for Texas Instruments. His unit contributed a fifth of the
company’s $13 billion in revenue last year. “The idea of IoT is to
connect it to the rest of the world.”
To allay companies’ security
concerns, Goren is pushing the deployment of multiple networks. That
way a wireless link that transmits information on the internal workings
of a machine can’t be hijacked to take control of the machine itself.
That’s pretty much what happened in a staged hack of a Jeep Cherokee in
July.
Intel says it’s already demonstrated the benefits of the
Internet of Things at one of its own plants. At a facility whose
location the company declined to name, a combination of sensors and
software correctly identified that vacuum pumps used in the manufacture
of silicon wafers were about to fail. What tipped them off?
Irregularities in the pumps’ normal pattern of vibrations.
Selling
factory owners on the use of electronics for discrete functions, such
as maintenance, will be easier than persuading them to overhaul their
entire setup so that every piece of equipment is churning out a stream
of data that can be parsed by computers. Some see a day when factories
will be able to talk directly to warehouses, which will be in
communication with stores, which will allow companies to tailor
production more carefully to demand. “The big goal of smart
manufacturing is to network the entire supply chain,” says Mark Watson,
an analyst for IHS. “That is a fair way off.”
