U F's Winning Robotic Submarine Provides Peek at the Future

ByAaron Hoover/UF News Bureau

On the heels of the rescue of a Russian
mini-submarine by a remotely operated sub,
students are leading their compatriots in
the design of the next generation of robotic
underwater vehicles.
The eight electrical and computer
engineering students' 30-pound submarine,
SubjuGator, placed first in a national
competition of 21 student-built robotic
submarines earlier this month. Although still
in the research stages, the sub points the way
toward a future of smart, compact robotic
submarines that could repair underwater
pipelines, guard ports and conduct military
offensive operations underwater.
"The military wants to have a significant
percentage of its battle infrastructure done
without humans in 10 years by 2015, 30
percent of all U.S. military vehicles should
be capable of autonomous navigation," said
Eric Schwartz, the electrical and computer

engineering faculty adviser for the SubjuGator
project. "These robotic subs could serve as
spy-bots or plant explosives. You don't always
want to use humans because we value human
lives and fighting is risky."
On Aug. 7, the remote-controlled British
"Scorpio" underwater vehicle disentangled
a Russian mini-submarine that had been
trapped for days beneath the Bering Sea,
saving the seven-member crew. The rescue
highlighted the capacity of remotely operated
subs to lend assistance in situations that are
either too dangerous or too deep for human
divers in this case, cutting the mini-sub
free of fishing nets and other debris that
had trapped it more than 600 feet below the
The next step is to make submarines
autonomous, or able to navigate and complete
tasks without human assistance. UF teams
have worked on that thorny challenge since
at least 1998, when they first entered the

then newly created Autonomous Underwater
Vehicle Competition. But while the UF team
placed in the top three in four of the previous
competitions,the Aug. 3-7 competition at the
Space and Naval Warfare Systems Center
near San Diego marked its first victory. The
competition is sponsored by the Association for
Unmanned Vehicle Systems International and
the Office of Naval Research.
Three teams achieved one of the competition's
main objectives: Finding an underwater pinger,
or sound-generating device, in a murky pond,
and then rising to the surface directly above
the pinger. But UF took first place because
SubjuGator's weight of 30 pounds was at least 40
pounds lighter than the other finalists.
"We forced ourselves into a small design
by buying a small shell," said Jim Greco, who
earned his bachelor's degree this spring and
begins his doctoral program this fall, both in
the UF department of electrical and computer
"All of our electronics had to fit within the
shell. At UF, to save money, we make a lot of our
electronics, whereas other teams might buy it off
the shelf."
Besides the electronics, the compact
SubjuGator has five thrusters, which gives the
computer controller complete three-dimensional
control, said another team member, Jose Carlo
Francis. It is powered by lithium polymer
batteries that allow it to operate for 90 minutes.
The design is completely new, although students
used a few parts from previous years.
Greco, the team's leader, said building the sub
was a good introduction to collaboration and
other skills of professional engineering.
"Our classes are great, but it's mostly just
theory," he said. "There aren't a whole lot of
practical applications, and this allows you to get
a leg up."
He added that one problem with today's
remotely operated submarines is that they require
a cable or other communications link to the
operator at the surface.
"If you're going down into the Marianna
Trench, the deepest spot on Earth, you can't
exactly drop a cable in there," he said.
Robotic subs, by contrast, remove this
impediment, but as Grego noted "they have
their own problems to work around." One major
challenge: programming the subs to "see" and
react to objects or changes in the terrain, a
difficult task for land-based robots made even
harder underwater by limited visibility and
difficulty of controlling the vessel.

UF Research Grid for High-Performance & Data-
Intensive Computing

What previously took researchers hours-and possibly days-to accomplish
now only takes minutes or seconds, thanks to a growing grid of UF's computing
resources and the UF High Performance Computing Committee, led by ECE
professor Dr. Alan George.
At the heart of this campus research grid is a new high-performance
computing center intended to provide a powerful baseline of computation and
storage infrastructure for the grid coupled with high-speed communications.
This grid will connect existing multiple independent facilities across campus
for the efficient and effective sharing of resources, and will assist with
collaborative research worldwide.
Phase I, installed in October 2004, focused on the College of Liberal Arts
& Sciences. Dr. Paul Avery of the Physics Department was the first faculty
investor. His investment was matched by the CLAS and the UF Office of
Information Technology.
"Phase II, which now focuses on the College of Engineering, will be
approximately twice the size of Phase I," George said.
To date, the ECE Department is the largest investor. The new equipment for
Phase II arrived in October and will be temporarily housed in the New Physics
Building until renovations in Larsen Hall are finished.
In November 2004, UF for the first time was included in the Top500
(www.top500.org) rankings (No. 221) at the global Supercomputing
Conference. Twice a year, Top500 generates a list of the sites operating the
500 most powerful computer systems in the world.
"We anticipate that UF will be in the top 100 when Phase II is completed,"
George said.
Phase III, which incorporates the UF Health Science Center, is already
under development and is expected to be operational in October 2006.

"Coming home" and "once a
Gator, always a Gator" are two
phrases that best describe David
Arnold's feelings about becoming
the newest ECE faculty member.
As a native Floridian who
grew up in a Gator family and earned two degrees from UF, it
was only natural for Arnold to return to UF after earning his
Ph.D. from Georgia Tech.
Currently, Arnold's research interests include design,
fabrication and characterization of magnetic and
electromechanical microsensors/microactuators, as well as
miniaturized power and energy systems.
As a teenager, Arnold and a friend built circuits from Radio
Shack kits. His interest in electrical engineering grew, and his
passion for learning and hands-on experimentation continues
to this day. He's looking forward to mentoring students in the
classroom and starting his research group. Also, Arnold is the
new HKN Student Chapter Faculty Adviser.
In his free time, Arnold enjoys flying. He earned his pilot's
license as an undergraduate, thanks to the influence of David
Bloomquist, a member of the Civil & Coastal Engineering
However, Arnold doesn't spend all his spare time in the
clouds. He also enjoys landscaping, home improvement, golfing
and traveling. He and his wife, Jennifer, also a UF ECE
alumnus, toured Ireland, Spain, France and Italy for three weeks
this summer.
"A truly amazing history lesson," Arnold said.

Yuguang "Michael" Fang was
promoted to full professor.
Fang is currently chair of the
IEEE Gainesville Section.
In addition to the various
technical program committees,
Fang is also an editor of the
following journals: IEEE
Transactions on Communications,
IEEE Transactions on
Wireless Communications,
IEEE Transactions on Mobile
Computing, Wireless Networks
Magazine, and IEEE Wireless
Communications and Mobile Computing. Among his awards are the
National Science Foundation Faculty Early Career Development
Award and the Office of Naval Research Young Investigator
Award. Fang teaches courses in Computer Networks, Computer
Communications, Wireless Networks, Performance Evaluation
of Communications Networks, High-Speed Networks, Queueing
Theory, and Network Security.

ECE food drive nets almost 2,000 cans
By Megan Gales a is E

The Department of Electrical &
Computer Engineering collected
nearly 2,000 cans of food in two
weeks. More than half of the cans
came in on the last official day of
the drive.
Theresa Permann and Shannon
Chillingworth, who both work
in ECE's Student Services
Office, organized the effort. They
originally hoped to gather at least
a few hundred cans. They raised
their goal several times, though,
as donations began to arrive.
Permann said the drive began
as a way to get to know their
students while helping the poor,
but became much more.
"It kind of turned into a
competition," she said.
A competition and a tradition.
They even had a plaque made
to present to the person who
donated the most cans. It will
spend the year with the winner,

then be passed to next year's
biggest giver.
Permann, who began working
at UF in September, said the
generosity of the University's
faculty, staff and students amazed
"These people are such givers,"
she said. "I can't believe the
hearts these people have."
ECE arranged to give the food
to the Bread of the Mighty food
bank in Gainesville. Operations
Manager Tom Orndorf came to
campus Friday to pick everything
up and take it back to the food
With the cans gone, Permann
and Chillingworth are thinking
about next year.
"We're hoping for more,"
Chillingworth said. "We
really hope it will continue as a
tradition. We'll raise the goal
every year.
