H.Y.Choi won BSPA
H.Y.Choi won BSPA
Hyun-Young Choi, Doctor’s course at the Lightwave Systems Research Laboratory (LSRL) of Department of Electrical Engineering of KAIST (Professor in charge Yoonchul Jung), won the Best Student Paper Awards (BSPA) in the Asia-Pacific Optical Communications 2006.
BSPA is awarded to the most prospective paper in the field of Optical Transmission, Switching, and Subsystems. Choi suggested an OSNR monitoring technique among performance monitoring techniques for the efficient maintenance and management of optical network in her paper. Her technique is based on a polarization-nulling method using the polarization features of optical signals. It employs polarization mode dispersion compensator and acousto optic tunable filter (AOTF) to prevent monitoring errors arising from polarization mode dispersion (PMD) and non-linear double refraction, which considerably improves the monitoring technique and makes it possible to demonstrate a technique proposed at ultra long haul network.

Korean Researchers Develop Skin-Like Tactile Sensor
THE KOREA TIMES2005.1.31(Mon)
A South Korean scientific research center said Sunday that it has developed a tactile sensor capable of functioning like human skin.
The left picture shows the letters of the Korea Advanced Institute of Science and Technology (KAIST) caught through a tactile sensor functioning like human skin and the right picture is its enlarged image. Scientists from KAIST developed the precision tactile sensor with 1-millimeter spatial resolution.
The tactile sensor is made of polydimethylsiloxane, a synthetic rubber, and has a 1-millimeter spatial resolution capability, the Korea Advanced Institute of Science & Technology (KAIST) said.
``Many tactile sensors have been developed so far, but ours has the highest spatial resolution capability, flexibility, softness and extensibility,’’ said Lee Hyung-kyu, who led the development project.
Late last year, the University of Tokyo unveiled a tactile sensor with a spatial resolution capability of 2 millimeters.
Lee said his team will announce the results of their research at an international conference on micro-electro-mechanical systems, to be held early next month in the U.S. city of Miami.
The new sensor is widely expected to lay the foundation for coating humanoids such as South Korea"s HUBO or Japan"s ASIMO with artificial skin.
HUBO is a humanoid robot recently developed by KAIST. It is capable of moving its fingers independently, dancing and shaking hands with people by using its 41 joints.
Japan"s ASIMO, an acronym for Advanced Step in Innovative Mobility, was unveiled in 2000 as the world"s most advanced bi-pedal robot.
Through several upgrades, it is now able to spin in the air, bend or twist its torso and maneuver around obstacles in its path.

KAIST Develops Thinking, Feeling Human-Like Robot
By Kim Tae-gyu / Staff ReporterTHE KOREA TIMES 2005.1.31(page 1)
South Korean scientists created the world"s first artificial species, a software robot with ``genes"" and ``chromosomes.""
Kim Jong-hwan, professor at Korea Advanced Institute of Science and Technology, said Sunday his team had developed a robot with 14 chromosomes, which gives the machine a ``personality.""
``This robot is a software-based one, sometimes called a sobot. It has a unique synthetic character determined by its specific combination of 14 chromosomes,"" the 47-year-old Kim said.
When Kim"s team gave a stimulus to the chromosome-equipped sobots, they showed totally different responses even under the same environment due to their distinctive personalities.
Several cognitive sensors enable the prototype models to identify 47 differing outside stimuli. The virtual robots also have 77 behavior patterns.
``Because a sobot is basically a software system, it can easily travel to other robots and multiply. In the middle of such processes, it can evolve through crossover and mutation,"" Kim said.
With the development of associated technologies, Kim expected the number of chromosomes would be augmented as sobots evolve to a more sophisticated species in the future.
The capacity to load large volumes of data is related to the evolution of sobots. Currently, 14 chromosomes consist of roughly 2,000 bytes of data.
The effort to incorporate the sobot into a platform, robot hardware, is now underway and Kim"s team looks to unveil the new-concept species as soon as next month.
``Diverse behavior patterns driven by sobots" specific personalities will be precisely translated into action just like the soul rules the body,"" Kim said.
Kim did not think the robotic evolution would lead to the human race being threatened; the concept of the recent blockbuster ``I, Robot.""
``If we design the chromosomes safely, the self-reproducing robot will not post a threat back to us,"" Kim said.
Kim first revealed the robotic breakthrough at a keynote speech of the International Conference on Autonomous Robots and Agents, held in New Zealand last December.
Kim is also known as pioneer in the field of robot football and has headed the Federation of International Robot-soccer Association (FIRA) since its foundation in 1999.
