U.S. and Korean Researchers Unveil Newest Research Team Member: Jaemi the Humanoid
- Project aims to enable humanoids to interact with people and their environment
June 1, 2009-- A Drexel University-led research team late last week unveiled the newest, most central member of its collaboration with a team of Korean researchers: Jaemi, a humanoid (HUBO). Jaemi HUBO embodies efforts to advance humanoid development and enhance the concept of human-robotic interaction. The project"s goal is to enable humanoids to interact with their environment, and enhancement plans include enabling the humanoid to move over rugged terrain, in unstructured environments and to interact socially with humans and handle objects.
The five-year project, funded through the National Science Foundation (NSF) Partnership for International Research and Education (PIRE) program, seeks transformative models to catalyze discovery through international research collaboration and train U.S. students and junior researchers to effectively think and work in global teams.
"The field of robotics is among the top 10 technology areas considered engines for economic growth. Korea understands this and is aggressively pursuing robotics. To stay competitive, the U.S. must do the same," said Mark Suskin, acting deputy director of NSF"s Office of International Science and Engineering. "NSF"s PIRE program and this robotics collaboration in particular, enable the U.S. to capitalize on research in other countries and remain competitive."
The PIRE research team is composed of researchers at The University of Pennsylvania, Colby College, Bryn Mawr College and Virginia Tech in the United States; and Korea Advanced Institute of Science and Technology (KAIST), Korea University and Seoul National University in Korea.
The team obtained a version of KAIST"s HUBO humanoid, which it named Jaemi HUBO and decided to house it at Drexel University. KAIST HUBO lab has become a model of cutting advance humanoid research by relatively small teams working on tight budgets.
KAIST excels in humanoid leg and body design, biped gait (walking, running, kicking), balance (modeling and control system design), and hardware integration. U.S. robotics researchers tend to enjoy an edge in locomotion over rugged, unstructured terrain; manipulation/grasping; cognition, perception and human-robot interaction; and vision (image, understanding, navigation).
This collaboration of American and Korean researchers will seek to draw on the expertise of each researcher and take Jaemi HUBO to the next level of development--that is, to improve Jaemi"s capabilities to navigate and manipulate objects and interact with people in unstructured environments. Such capabilities demand information technologies like cognition, perception and networking areas. Targeted enhancement features include a capability to move over rugged terrain and in unstructured environments and to handle objects and interact socially with humans.
Jaemi HUBO will also educate the American public, particularly young people, about the science of robotics. This education process began at the Please Touch Museum in Philadelphia on May 28, 2009, when Jaemi HUBO was unveiled and introduced to a crowded audience of children and a few adults. Neither male nor female,Jaemi connected with the children, boys and girls alike. Guided by a Drexel University graduate student, Jamei moved, spoke, danced, shook hands and lead the children in a game of Simon Says. Such access to Jaemi HUBO starkly contrasts with that afforded by other high-profile humanoids that are often protected trade secrets, largely inaccessible to the public.
Museum curators are pleased to have had Jaemi visit and entertain kids during the weekend. "At the Please Touch Museum, we promote learning through a variety of senses," said J. Willard Whitson,the museum"s vice president for exhibits and education. "A humanoid not only embodies our goal of building layers of knowledge in young people, but Jaemi helps all of us celebrate the playful side of technology."
Jaemi HUBO is now at its permanent home at Drexel University, from which travel and guest appearances may be arranged by appointment. Journalists interested in meeting and interviewing Jaemi HUBO and other research team members are encouraged to contact Lisa-Joy Zgorski at lisajoy@nsf.gov.

International News Outlets Report on KAIST's On-Line Electric Vehicle Project
International news agencies such as the Associated Press and Reuters have recently reported on the "online" electric vehicle project KAIST is proceeding with. A number of newspapers abroad including the New York Times and the South China Morning Post of Hong Kong published the articles. Following are excerpts from those reports.

S. Koreans designing "online" electric vehicles
By JEAN H. LEE
Associated Press
Urban visionaries in London and Seoul, two of the world"s busiest capital cities, foresee buses gliding through their streets with speed, ease and efficiency _ without emitting the exhaust fumes that scientists say are contributing to global warming.Under Mayor Boris Johnson"s vision, London"s iconic red double-decker Routemaster buses would be back on the streets _ but powered by electricity, not gasoline.
Engineers at South Korea"s top-ranked KAIST university are meanwhile working on a novel prototype for an electric vehicle system: one that provides power on the go through induction strips laid into the roadway.
Cities _ which house 75 percent of the world"s population and generate 80 percent of its pollution _ must take leadership in tackling the problem of polluting emissions, Johnson said Monday in Seoul on the eve of the third C40 Large Cities Climate Summit.
"I think as a collective of cities, what we should be doing here in Seoul is agreeing that we are going to stop the endless addiction of mankind to the internal combustion engine," he told reporters. "It"s time that we moved away from fossil fuels. It"s time that we went for low-carbon vehicles."
"Cars form many problems that we see in Korea as well as other countries. We use hydrocarbon organic fuels, mostly petroleum, and that, in turn, creates environmental problems _ and Seoul is notorious," said Suh Nam-pyo, president of KAIST in Daejeon, south of the South Korean capital.
Seoul, population 10 million, is getting warmer three times faster than the world average, the National Meteorological Administration said Monday.
The obvious solution, Suh said, is to "replace all these vehicles with vehicles that do not pollute the air and do not use oil."
Back in March, Johnson zipped down a British highway in a U.S.-made electric car that he wrote marked "the beginning of a long-overdue revolution."
He rhapsodized in a Telegraph newspaper editorial that the Tesla has no exhaust pipe, carburetor or fuel tank, and "while every other car on that motorway was a-parping and a-puttering, filling the air with fumes and particulates, this car was producing no more noxious vapours than a dandelion in an alpine meadow."
Last month, he launched an ambitious plan to get 100,000 electric cars onto the streets of London by 2015. He pushed for the creation of 25,000 charging stations and vowed to convert some 1,000 city vehicles to make London the "electric car capital of Europe."
"The age of the diesel-emitting bus has got to be over in London," Johnson said.
And scientists are still grappling with the massive, sensitive, costly and fast-depleting batteries that take the place of international combustion engines and gasoline. Electric cars run between 40 and 120 miles (60 to 200 kilometers) on one charge, and it takes anywhere from two to seven hours to fully recharge, said Christian Mueller of the IHS Global Insight consulting firm.
"Everybody is frantically working on coming up with a viable electric car," he said from Frankfurt, Germany.
Batteries "aren"t yet at a state where we can say they are cheap, they"re reliable and they"re easy to come by. They all still have their technical drawbacks," said Mueller, who specializes in electrics and electronics.
Suh, an MIT-trained inventor with some 60 international patents to his name, approached the challenge from another angle.
"Why not have power transmitted on the ground and pick it up without using mechanical contact?" he said in an interview in his office overlooking the staging grounds for the university"s electric cars.
KAIST"s "online" vehicles pick up power from trips, or inverters, embedded into the road rather than transmitted through rails or overhead wires. A small battery, one-fifth the size of the bulky batteries typically used, would give the vehicle enough power for another 50 miles (80 kilometers), said Cho Dong-ho, the scientist in charge of the project.
South Korea produces its own nuclear power, meaning it can produce a continuous supply of energy to fuel such a plan.
President Lee Myung-bak, whose government gave KAIST $50 million for two major projects, including the "online" electric vehicle, took a spin in February.
Online buses are running at the KAIST campus and will begin test runs soon on the resort island of Jeju.
But Seoul, which has promised to set aside $2 million for the underground charging system, is within Suh"s sights. He said 9,000 gasoline-fueled buses now crisscross the capital, with 1,000 going out of commission each year. He envisions replacing those aging buses with electric models. Initial test runs are expected to take place this year.
Mueller, the consultant, called it a creative approach with potential.
"It sounds very intriguing; you don"t store your energy, you provide it on the go." he said. "The (battery) storage problem is overcome instantly. That would be a very intriguing way of doing it."

South Korea tries recharging road to power vehicles
By Jon Herskovitz
SEOUL (Reuters) - South Korea"s top technology university has developed a plan to power electric cars through recharging strips embedded in roadways that use a technology to transfer energy found in some electric toothbrushes.
The plan, still in the experimental stage, calls for placing power strips about 20 cm (8 inches) to 90 cm (35 inches) wide and perhaps several hundred meters long built into the top of roads.
Vehicles with sensor-driven magnetic devices on their underside can suck up energy as they travel over the strips without coming into direct contact.
"If we place these strips on about 10 percent of roadways in a city, we could power electric vehicles," said Cho Dong-ho, the manager of the "online electric vehicle" plan at the Korea Advanced Institute of Science and Technology.
The university has built a prototype at its campus in Daejeon, about 140 km (90 miles) south of Seoul, for electric-powered golf carts and is working on designs that would power cars and buses.
The system that can charge several vehicles at once would allow electric cars and buses to cut down on their battery sizes or extend their ranges.
The non-contact transfer of electricity, also called inductive charging, works by magnets and cables on the underside of the vehicle making a connection with the current in the recharging strip to receive power as they travel over it.
It is employed in some brands of electric toothbrushes that are sealed and water resistant, which do not need to be plugged into anything but use a magnetic connection to receive energy while resting in a cradle.
The recharging strips, which are attached to small electrical stations, would be laid in places such as bus lanes and the roads running up to intersections so that vehicles could power up where traffic slows down, Cho said.
The system will be tested later this year for use in the bus systems of Seoul and other South Korea cities while some of the country"s automakers are also cooperating in the project.
Unlike electric lines used for trams, vehicles do not need to be in constant contact with the strips and a person can touch the lines without receiving a shock.
The system so far has proven safe to humans and machinery, Cho said.
The cost of installing the system is an estimated 400 million won ($318,000) per kilometer of road. Electricity is extra.

KAIST Ranked Seventh in Chosun-QS 2009 Asian University Rankings
- Major Criteria in Research, Education, Globalization
KAIST ranked top in Korea and seventh in Asia in a ranking compiled jointly by the Chosun Ilbo, a major Korean daily, and global university evaluation institute QS of Britain.
In the rankings released on Tuesday (May 12), KAIST scored 94.9 based on the full 100 of the top-ranking university, the University of Hong Kong. KAIST was closely followed by Seoul National University (SNU), which ranked 8th in the Asian ranking. KAIST outpaced SNU in terms of globalization, but lagged behind in terms of peer review and recruiters review.
The Chosun Ilbo said that KAIST achieved the distinction by encouraging competition among research professors, introducing competitive educational systems such as conducting all classes in English, and speeding up globalization drive based on a strong leadership of President Nam-Pyo Suh.
In an interview with the daily published on the same day, President Nam-Pyo Suh expressed enthusiasm for stepping up his university"s drive to make it one of the world"s leading research universities, without resting on its present reputation. "The goal of KAIST is to stand at the forefront in addressing critical problems facing the humanity in the 21st century. The problems include alternative energies and transportation and logistics. If we resolve these problems, KAIST will join the ranks of the world"s best universities," Suh said.
The evaluation, the only such survey in Asia, was conducted with 463 universities in 11 countries, including 106 in Korea. The universities were ranked for competitiveness in four categories -- research quality (60 percent), teaching quality (20 percent), graduate employability (10 percent) and international outlook (10 percent).
The top-ranked University of Hong Kong was followed by Chinese University of Hong Kong, Tokyo University, Hong Kong University of Science and Technology, and Osaka University.
The top 100 Asian universities include 17 Korean universities, 33 Japanese, 11 Chinese, seven Indian, six in Hong Kong and two in Singapore.
Universities were ranked through a quantitative analysis based on data submitted by the universities in March and a qualitative analysis based on the competitiveness of professors and graduates evaluated by about 3,100 academics and businesspeople around the world.
Meanwhile, KAIST was ranked 95th among top 200 universities of the world in the Times Higher Education-QS World University rankings in 2008. It ranked 34th in the area of engineering and information technology, and 46th in natural science.

Prof. Chong Unveils New Human Movement Model
A KAIST research team headed by Prof. Song Chong of the School of Electrical Engineering and Computer Science has developed a new statistical model that simulates human mobility patterns, mimicking the way people move over the course of a day, a month or longer, university sources said on Tuesday (May 12).
The model, developed in collaboration with scientists at North Carolina State University, is the first to represent the regular movement patterns of humans using statistical data.
The model has a variety of potential uses, ranging from land use planning to public health studies on epidemic disease.
The researchers gave global positioning system (GPS) devices to approximately 100 volunteers at five locations in the U.S. and South Korea and tracked the participants" movements over time. By tracing the points where the study participants stopped, and their movement trajectories, researchers were able to determine patterns of mobility behavior.
The researchers were then able to emulate these fundamental statistical properties of human mobility into a model that could be used to represent the regular daily movement of humans. The model, called Self-similar Least Action Walk (SLAW), will have a wide array of practical applications.
The research, "SLAW: A Mobility Model for Human Walks," was presented on April 20 at the 28th IEEE Conference on Computer Communications in Rio de Janeiro, Brazil. The National Science Foundation of the U.S. funded the research.

KAIST Research Team Discovers Process for Rapid Growth of N-Doped CNT Arrays
A team of scientists led by Profs. Sang-Ouk Kim, Won-Jong Lee and Duck-Hyun Lee of the Department of Materials Science and Engineering has found a straightforward process for rapid growth of wall-number selected, nitrogen-doped carbon nanotube (CNT) arrays, university officials said on Monday (March 16).
KAIST researchers prepared highly uniform nanopatterned iron catalyst arrays by tilted deposition through block copolymer nanotemplates. This remarkably fast growth of highly uniform N-doped CNTs, whose material properties and chemical functionalizability are reinforced by N-doping, offers a new area of a large-scale nanofabrication, potentially useful for diverse nano-devices.
Carbon nanotubes (CNTs) are of broad technical interest in electronics, photonics, energy devices, and other applications. However, establishing a straightforward process for mass production of uniform CNTs with desired structure and properties has been a long-standing challenge.
In particular, it was strongly desired to precisely control the numbers of walls and diameter of CNTs, which are decisive parameters for the physical properties of CNTs. In this respect, the preparation of monodisperse catalyst array having a narrow size distribution is generally considered an effective pathway to produce well-defined CNTs, since the number of walls and diameter of the produced CNTs are closely related to the catalyst size.
The finding was featured in the March 13 edition of Nano Letters, a leading journal in the nano technology field.
