The Key to Healthy Humans, Safe Spacecraft and Prospering Plants

Via The University of Arizona College of Engineering | October 29, 2018


Wolfgang Fink (Right) has always had a knack for seeing how the pieces of a puzzle fit together. Once, when a team of researchers at NASA’s Jet Propulsion Laboratory was stumped on how to fix a problematic planetary rover arm, he suggested using a method he’d developed to improve the function of proteins, pointing out something no one had thought of before: Both robot arms and proteins have joints. It worked.

Today, it means that the electrical and computer engineering professor — who has joint appointments in biomedical engineering, ophthalmology and vision science, systems and industrial engineering, and aerospace and mechanical engineering — can continue finding connections across disciplines to solve a world of problems… Continue reading.

Humans, Machines Enter a New Orbit

Via University of Arizona | March 28, 2018

For almost 20 years, humans have maintained a continuous presence beyond Earth. The International Space Station has provided a habitat where humans can live and work for extended periods of time. Yet, despite having established a permanent base for life in space, terra firma is always in reach — within 254 miles, to be exact. If a crew member were to fall seriously ill, he or she could make the return trip back to Earth in a matter of hours.

“As soon as you venture beyond low Earth orbit, to go to Mars or even further, bailing out no longer is an option,” says Wolfgang Fink, associate professor and Keonjian Endowed Chair in the UA’s College of Engineering. “You’re on your own.”

Fink predicts that in the not-too-far future, humans will work side by side with robotic machines, non-human intelligence and smart devices in ways never seen before. Human logic and thinking will be joined by, and complemented by, artificial brains and reasoning algorithms…

Endowing Ability in Computers and Classes

Via University of Arizona | March 30, 2016

Planetary exploration and medical diagnostics might seem like topics for researchers in two different fields. But for Wolfgang Fink, the connection between the two is about equipping machines to make judgments normally entrusted to people.

“You can’t take the experts everywhere,” Fink says.

Consider extreme space environments, where it’s dangerous and costly to send astronauts. Conventional rovers are controlled from Earth, but the distance delays commands by hours. To advance the science, Fink is developing robots to react with excitement and curiosity to objects that differ from their typical surroundings. Working with other instruments in space, such as blimps, next-generation rovers will independently prioritize what to investigate further.

“These next-generation robotic missions will simultaneously explore distant locales at several levels — from orbit, from the air, and on the ground — to home in on important geology, hydrology, climate, and possibly astrobiology on distant worlds,” Fink says… Continue reading.

Designing a Real Life BB-8

Via R&D Magazine | December 15, 2015

In three days “The Force Awakens.”

It’s undeniable the Star Wars franchise has had a lasting effect on popular culture, bringing science fiction to the mainstream and creating a sub-culture all its own.

In 1977, “Star Wars Episode IV: A New Hope” hit theaters. Despite studio expectations the film would flop, it ended up dazzling audiences. Among those watching in awe was a young Wolfgang Fink, who is now an associate professor of electrical, computer and biomedical engineering, and the Keonjian Endowed Chair of Microelectronics at the Univ. of Arizona.

“It was a great experience because I think Star Wars started a new genre of movie, the science fiction fairytale, if you will. It was very fascinating,” said Fink in an interview with R&D Magazine. “Star Wars was kind of always way ahead of its time in terms of new technologies… Continue reading.

‘Star Wars’ Science: How Would BB-8 Work?

Via Arizona | December 9, 2015

The real star of the upcoming "Star Wars" movie may not be a human or a Wookie. Instead, it may be a round, 2-foot-tall astromech droid named BB-8.

It may look great on the screen, but could BB-8 exist in real life?

University of Arizona researcher Wolfgang Fink would know, as an expert in artificially intelligent Mars rovers — and as an unabashed "Star Wars" fan.

Fink, who spends an extraordinary amount of time around robots, has done his share of thinking about the astromech droids seen in the franchise. And with J.J. Abrams’ "Star Wars: The Force Awakens" opening in theaters on Dec. 18, Fink is focused on BB-8.

Compared to that of R2-D2 and C-3PO from previous "Star Wars" incarnations, the design of BB-8 has "a striking advantage," Fink says.

"R2-D2 is on three legs and rolls around, so the challenge there would be if you have rugged terrain. Now, of course, C-3PO is a humanoid robot and can climb just like we do," he says.

Fink is an associate professor of electrical, computer and biomedical engineering at the UA, as well as the Keonjian Endowed Chair in Microelectronics. In his lab, he designs and builds artificially intelligent, autonomous Mars rovers. But as he reflects on his love of "Star Wars" in an intentionally dim office, he wields a crimson-red light saber that vacillates between a dull hum and a piercing whoosh as he waves it left to right.

Building Curiosity Into Technology

Via U. Arizona | August 27, 2015

The year is 2045.

Geologists have landed on various bodies in the solar system and are exploring alien landscapes. On Mars, a geologist climbs up a slope after spotting a peculiar-looking rock. On Saturn’s moon Titan, a blimp glides through the brown haze, surveying the methane lakes below while directing another explorer to cross the lake and investigate an odd feature sticking out above the surface.

These planetary geologists are not human. They’re robots, built in various shapes and forms. Some are rovers, others hover in the atmosphere and others float. All have one thing in common: They are hardwired to explore the unknown. They are curious.
Unlike conventional planetary rovers, which are basically cameras on wheels controlled by humans on Earth, these new planetary explorers go about their work autonomously, capable of making decisions on their own.

“In environments where you need a curious explorer with the ability to spot unusual and interesting objects, but you either can’t or don’t want to send humans, you have to rely on robots with a built-in sense of curiosity and the ability to make decisions autonomously,” said Wolfgang Fink, who heads the Visual and Autonomous Exploration Systems Research Laboratory at the University of Arizona’s College of Engineering.

“To accomplish this, we have to instill algorithms in the robot that will create ‘excitement’ about an object if it is different from the surrounding environment.”

UA Engineering Turns Smartphones Into Eye-Screening Tools

Via UA News | November 26, 2014

University of Arizona researchers are developing technology that converts smartphones into powerful eye-examining instruments that could prevent millions of people from going blind.

Wolfgang Fink, professor of electrical and computer engineering and biomedical engineering, is principal investigator of a new project funded by the National Science Foundation Partnerships for Innovation: Building Innovation Capacity program to create “smart ophthalmoscopes,” specialized instruments for examining various parts of the eye’s interior. The devices, which can be attached to any smartphone, and accompanying software will enable health care providers, particularly in remote areas, to quickly and easily determine if patients are at risk of losing their vision.

The need is great. The World Health Organization has estimated that of the 285 million people worldwide who are visually impaired, 39 million are blind. Tragically, nearly 80 percent of this blindness is caused by treatable conditions such as cataracts, glaucoma, age-related macular degeneration and diabetic retinopathy. Available treatments can slow and even stop the progression of vision loss when these conditions are caught early enough.

But for those in remote areas — rural populations, boat crews and military service personnel, for example — eye exams are not readily available, and patients who do reach medical centers often arrive too late.

A New Tool in the Search for Extraterrestrial Life: A Tricked-Out Point-and-Shoot

Via U. Arizona News | February 7, 2014

The next time a NASA rover blasts off to explore Mars or some other planet, it might be equipped with a new type of “do-it-all” camera developed by an engineering team at the University of Arizona.

The prototype of the “Astrobiological Imager” – described in a research paper featured on the cover of a recent issue of the journal Astrobiology – consists of an off-the-shelf digital point-and-shoot camera with some surprisingly simple modifications. A slightly more sophisticated version, mounted on a rover, could do what even NASA’s latest and greatest Mars rover, Curiosity, can’t: identify, photograph and even analyze patches of soil or rocks from afar and in extreme close-up, all with the same camera.

The team figured out how to take advantage of different lens adapters that can be mounted in front of a single camera to enable it to take images ranging from a macroscopic scale – think landscape – all the way down to a microscopic scale – think cells and bacteria – thus spanning at least six orders of magnitude.
“For each scale, there is of course one or even several imagers that are superior to our instrument for that particular scale,” said Wolfgang Fink, an associate professor in the UA Department of Electrical and Computer Engineering who led the project. “However, there is no instrument out there that can go across several orders of magnitude.”

Fink explained: “Think of the world’s best decathlete as opposed to the world record holders in each individual discipline. That’s the best analogy. Our camera is the best decathlete.”

Breakthrough in Retinal Implants Expected to Restore Sight to the Blind

Via Arizona Engineer | November 1, 2013

Retinal implants have not lived up to their potential, argues a joint UA-German research team, until now.
Researchers at the University of Arizona and University of Tübingen have made a breakthrough in retinal implant technology that could help people who have lost their sight see more than just light and vague shapes.

Wolfgang Fink, an associate professor in the UA departments of electrical and computer engineering and biomedical engineering, is researching new implant design and methods of electrical stimulation of the retina that will enable implants to produce much clearer images.

Fink conducted the research jointly with Erich Schmid, professor emeritus of theoretical atomic and nuclear physics at the University of Tübingen, Germany. Fink will present the team’s findings in San Diego during the Nov. 6-8, 2013 IEEE International Conference on Neural Engineering, organized by the Engineering in Medicine & Biology Society.

Only a handful of companies and research institutions worldwide are developing retinal implants, which stimulate surviving retinal cells in people who have lost their sight due to common degenerative diseases such as macular degeneration and retinitis pigmentosa. Implant patients can usually detect the presence of light, but the images they perceive are very low resolution.

“Current technologies and methods are far behind what can be done,” said Fink, who is working with Tech Launch Arizona to patent the new technology and license it to retinal implant developers.

Robotic Lake Lander Could Explore Bodies of Water on Other Planets

Via Gizmag | March 21, 2012

Ask someone to picture a robotic roving vehicle, and chances are they’ll think of something with wheels, like the Mars Rover. If an alien civilization were sending a craft to explore Earth, however, they might be better off using a boat – after all, the majority of our planet’s surface is covered with water. Saturn’s largest moon, Titan, similarly has a pretty wet surface, as it contains lakes of liquid hydrocarbon. Wolfgang Fink, an engineer with the University of Arizona, has designed an aquatic rover for exploring those lakes.

UA Professor’s Autonomous Robotic Space Exploration Research Featured in Science Magazine

Via Arizona Engineer | August 3, 2010

Science magazine recently published an article featuring UA professor Wolfgang Fink’s research on using intelligent robots for planetary exploration.

Science was founded in 1880 using seed money provided by Thomas Edison, and has grown into the world’s most widely read general science journal, with more than a million readers worldwide.

The main thrust of the July 30 Science article, “Making Smarter, Savvier Robots” by Sam Kean, was that “robots are pretty dumb” and must rely on scientists back on Earth to control their exploratory missions. Kean pointed out that only a few dozen scientists are developing robots with true high-level independence that enables them to avoid danger while investigating planetary features of their own choosing.

One of those scientists is Wolfgang Fink, associate professor of electrical and computer engineering and biomedical engineering, who holds the Edward and Maria Keonjian Endowed Chair in the College of Engineering, and directs the Visual and Autonomous Exploration Systems Research Laboratory. He also has a joint appointment in the UA department of ophthalmology and vision science.
