The
Robot That Knew Just Enough
by Jeffrey Winters |
The four-legged robot in the engineering
lab at Cornell University in Ithaca, N.Y., looks a bit like something
out of a nightmare: a mechanical spider or a crawling hand. But the robot
can do something that mechanical engineers have only dreamed about for
decades. The robot learns how to move in its environment and reacts to
physical changes. When it's damaged, it relearns how to walk.
The most remarkable thing about this robot, however,
is what it lacksa preprogrammed map of its environment. As described
in the November 17 edition of the journal Science, the machine
uses stored sensory input and a computer algorithm to figure out where
it is and how it's oriented. This self-reflexive ability may some day
help other robots perform tasks as wide-ranging as exploring Mars or repairing
complex machines.

| This robot, built in a Cornell
University laboratory, can figure out on its own how to crawl across
a table. |
The Cornell robot, created in the lab of Hod Lipson, an assistant professor
of mechanical engineering, is programmed only with the knowledge of what
its parts are, not where they are on its body or how to use them to crawl
forward. But much like a newborn learns from trial and error, the robot
sends commands to various actuators and notes the results. The key step
comes next: The results are compiled and a model is created that best
explains them. For instance, commands to separate motors on the same leg
will cause the leg to stretch out.
After many cycles of model building, the robot tries to move forward.
The results weren't exactly pretty, usually involving pulling itself
across a table. Next, the researchers broke a bit off one of the legs
and the robot had to figure out how to move all over again. But using
the model-driven algorithm, the robot found a new way to ooch itself across
the surface.
It's still too soon to begin building self-awareness into machines
in the field, but in time, model-based algorithms could instill a real
autonomy into robots tasked with performing in extreme conditions. Someday,
for example, submersible robots may be able to automatically compensate
for ocean currents as they work on oil pipelines.

Asian
Solar Power
in Canada
by Peter Easton |
The Japanese unit of a Chinese manufacturer
has struck a distribution deal to market solar power equipment in Canada.
Suntech Power Holdings of Wuxi, China, a manufacturer of photovoltaic
cells and modules, said that its subsidiary, MSK Corp., has reached an
agreement with ARISE Technologies Corp. of Kitchener, Ontario, to distribute
the MSK Just Roof system in Canada.
MSK calls Just Roof a "building integrated photovoltaic,"
or BIPV, system. It functions as a fully self-contained watertight roof
structure, eliminating the need for traditional roofing materials below
the panels, according to the company. The Just Roof product, which can
be seamlessly integrated into home design, is particularly suited for
new construction projects, but can also be retrofitted to existing rooftops.
"The Just Roof BIPV system offers individual homeowners a practical
means of integrating solar energy generation systems into a building's
structure," said Zhengrong Shi, Suntech's chairman and CEO.
"MSK's BIPV systems are already seeing substantial sales
penetration in Japan, where they are even being offered as a standard
feature by some of our home builder customers,"
he added.
Consumer demand for solar products in Canada may be driven by recent initiatives
that are promoting the use of renewable energy.
Under Ontario's Standard Offer Program, the provincial government
will pay approximately 37 cents per kilowatt-hour for power generated
by solar energy over a period of 20 years. To promote this new policy,
the Canadian government recently partnered with ARISE and MSK to install
North America's first Just Roof system on a demo home in Waterloo,
Ontario.
Since MSK Just Roof was first introduced, more than 4,000 systems have
been installed in Japan. ARISE, which is dedicated to accelerating the
use of solar energy in mainstream North American markets, will begin marketing
the MSK Just Roof system early next year.
Suntech's subsidiary, MSK Corp., is one of Japan's largest
PV manufacturers and a leader in building-integrated photovoltaics.
Suntech has customers in Europe, Japan, China, and the United States.

Antenna
Solutions Firm Makes
Two Purchases
by Peter Easton |
A manufacturer of antenna solutions, electromagnetic
interference shielding products, telematics, and thermal management solutions,
Laird Technologies, is branching out.
The St. Louis-based company last month made a pair of acquisitions: Steward
Inc. and Coollab AB, which trades as "Supercool."
Laird Technologies purchased Steward and its subsidiaries for a total
of $52.5 million.
Steward is a provider of ferrite-based products that are used to remove
EMI "noise" and other signals at unwanted frequencies from
conductors. Steward's revenues in its fiscal year ending Sept.
30, 2006, were $50 million.
The company is based in Chattanooga, Tenn., and also has factories in
Mexico and China.
Headquartered in Gothenburg, Sweden, Supercool is a leading provider of
custom-designed, thermoelectric-based assemblies, which are used in thermal
management
applications that span a wide range of markets.
These products integrate thermoelectric modules, temperature control systems,
heat exchangers, external packaging, and in some cases, fans or pumps
to provide thermal management systems to customers. Supercool's
products are used in a diverse range of applications in the telecommunications,
medical, food and beverage, electronics, and automotive industries. Sales
revenues for 2006 are expected to be $11 million. Laird paid $17.6 million
for Supercool.
Supercool also has a business development center in San Rafael, Calif.
The company's sales are concentrated in Europe, but sales growth
is most rapid in North America.
Laird's products are used in the telecommunications, data-communications,
computer, general electronics, network equipment, aerospace, defense,
automotive, and medical equipment industries.

Museum
Honors Black Engineers
by Alan S. Brown |
Chicago's Museum of Science and Industry
will honor African-American industrial designers with a six-week interactive
exhibit, Designs for Life,will start later this month. The exhibit,
part of the Museum's annual Black Creativity program, hopes to focus attention
on a career that bridges the gap between technology and consumer application.
"Industrial design is a career field that is not often recognized,
but industrial designers make the products that we use every day,"
said Ricky Penick, chair of the 2007 Black Creativity program. "It's
truly a career that blends science, technology, business, creativity,
and artistry."
 |
| The Chrysler 300C, designed by
Ralph Giles, captured more than 20 awards, including America's
Most Wanted Automobile of 2005. |
The exhibit features the designs of 30 African-Americans. Some, like
Ralph Giles of DiamlerChrysler Corp., are well-known superstars. Giles'
Chrysler 300C, with its fat front grille and hip-hop flair, was a very
big success for the company. It also picked up more than 20 awards, including
America's Most Wanted Automobile of 2005.
The exhibition also features Edward T. Welburn Jr., vice president of
global product development at General Motors Corp., whose highlights range
from racing vehicles and concept cars to trucks and Hummers. GM design
manager Crystal Windham, who develops Saturns, is also featured in the
show.
Automotive stylists may be superstars of the design world, but others
have made equal contributions in areas that are so common that we tend
to take them for granted.
Charles Harrison, a retired academic, was the first African-American executive
hired by Sears Roebuck. He had his hand in everything, from the View-Master
and the first plastic garbage can to back massagers, hedge clippers, fishing
equipment, and can openers.
Carole Bilson, vice president of global design and usability for Pitney
Bowes Inc., has won awards for business products easy enough for consumers
to use. Lamont Morris of Hasbro Inc. has designed scores of toys, from
the Play-Doh Compound Extruder and Weebles Playground to Bubbles the Pup
and the Real Meal Oven.
Roy Thompson, lead designer with Proteus Design of Cambridge, Mass., has
worked on DJ turntables and padlocks. Vince Haley, director of product
development at Design Inspiration in Orrville, Ohio, has put in time on
everything from suddenly ubiquitous gift wrap storage containers to vacuum
cleaners, mops, and insect foggers.
According to the museum, guests at the exhibit will be able to try to
develop their own designs. In addition to the industrial design exhibit,
Designs for Life will include educational programming, a juried
art exhibition, symposia, performances, a fundraising gala, and a career
bowl for Chicago-area students. The exhibit will be open from Jan. 12
through Feb. 28.

Clear
the Runway
by Jean Thilmany |
Runway debris, known in the airport industry
as foreign object debris, or FOD, can be as small and seemingly innocuous
as a broken suitcase wheel, a bolt, or a discarded plastic bag. But small,
lost parts have the potential to do serious, sometimes catastrophic, damage
to aircraft.
A report on the July 2000 Paris Concorde crash, in which 113 people died,
said investigators suspected that a metal strip found on the runway could
have gashed one of the plane's tires.
That was an extreme case, and plane crashes are relatively rare in our
time. But the debris costs plenty. Each year, loose objects on airport
runways, taxiways, and aprons cost the global aviation industry an estimated
$4 billion, said Brett Patterson, the director of operations, safety,
and planning for the Vancouver International Airport Authority.
Vancouver International has installed a system that detects runway debris
via radar, so it can find small objects loose on the airport's
runways in all kinds of weather.
The airport now uses the radar system called Tarsier from QinetiQ of Farnborough,
England, home of the Farnborough Air Show. QinetiQ said the system can
detect and locate small objects to within a few feet of where they are
on the ground.
QinetiQ developed its detection system in the wake of the Concorde crash,
said Hal Kruth, group managing director for the company's security
sector.
Before the installation of Tarsier, airport employees personally went
out and inspected airport runways between takeoffs and landings. It is
common practice at all airports, Patterson said, and visual checks are
still done at Vancouver International.
Debris management measures also include strategically placing garbage
barrels at locations where loose objects are most likely to be discovered.
Four Tarsier radar units at the Vancouver airport provide continuous coverage
of the north and south runways, each of which is nearly two miles long.
The four units are mounted on towers set back from the runway for maximum
coverage. A display unit provides the airport authority's operations
team with all-weather, around-the-clock runway pictures in its operations
center. The display unit gives staff coordinates of reported debris. Coordinates
are entered into a vehicle's GPS navigation system so that staff
can go directly to the location and retrieve the object.

Contract
Anticipates New Aircraft Rules
by Peter Easton |
In anticipation of forthcoming U.S. Federal
Aviation Administration and European Aviation Safety Agency rules, Airbus
has awarded Parker Hannifin Corp. of Cleveland the fuel tank inerting
system contracts for the Airbus A400M military transport aircraft and
Airbus long-range and single-aisle aircraft. These aircraft could include
the A318, A319, A320, A321, A330, and A340.
The value of the contracts could exceed $500 million over the life of
the programs, which are respectively forecast to extend over several decades.
Parker is a leader in motion and control technologies.
The Parker fuel tank inerting system uses air separation modules, or ASMs,
which remove oxygen from air and distribute the nitrogen-rich result to
the aircraft's center fuel tank, thereby reducing the flammability
of fuel vapors in the tank.
As the tier-one integrator, Parker will provide the core inerting technology
subsystem consisting of the ASMs that produce the nitrogen and integrate
it with a temperature-control subsystem developed by Liebherr Aerospace,
Airbus's primary environmental-control-system supplier.
The ASM fiber technology for the Airbus programs is patented and owned
by Parker.
The Parker inerting system is expected to enter into service on Airbus
aircraft in 2009.
