Geminoid videos

22 Jul 2006

Geminoid with creator IshiguroGeminoid is a remote-control doppelganger droid designed by and modeled after Hiroshi Ishiguro, professor at Osaka University and researcher at ATR Intelligent Robotics and Communication Laboratories. Robot Watch has released some short videos, which you can see at the links below. Video format is WMV.

Video 1: Ishiguro introduces himself through Geminoid.

Video 2: This segment shows Geminoid's facial movements. The telepresent Ishiguro explains, "When someone touches Geminoid, it seems as if I am the one being touched."

Video 3: Geminoid (Ishiguro) doesn't like it when you touch his face.

Video 4: Geminoid is programmed so that his head continues to move, even when not being specifically controlled.

Video 5: Sitting next to Geminoid, Ishiguro discusses his research concerning "presence."

In Latin, gemin means "twin" or "double," while -oid is a suffix indicating a "likeness to something else." Hiroshi Ishiguro would say that his Geminoid is like a twin. The body is a copy of Ishiguro's, and the shape of Geminoid's skull was created based on MRI scans of Ishiguro's head. And Geminoid shares some of his mannerisms.

Geminoid's body, which was produced by Kokoro, makers of the Actroid line of fembots, has 46 degrees of freedom and is driven by a system of air compressors. The skin consists of soft, silicone rubber. Confined to a chair at the moment, the android is unable to stand up and move about on his own. Communication and power cables exit his rear end and snake through the shaft of the chair out of sight. It took 6 months of work to develop the body and about 2 to 3 months to develop the software.

One of the purposes for creating Geminoid is to explore the concept of tele-existence -- to figure out what is needed in order to copy an actual human's "presence" so that he or she may exist in two places at once. "I wonder how possible it is to separate one's inner self and outer self, to create distance between one's body and soul," Ishiguro says.

Giant interactive squid robot in the works

20 Jul 2006

Giant squidIn squid-crazy Hakodate, squid fishing is big business, the local specialties include shio ramen (squid-topped ramen) and ikasomen (raw squid cut into the shape of somen noodles), the summer festivals have residents busting squid-like moves in a dance called ika-odori (a squirmy version of the traditional bon dance performed at summer festivals throughout Japan), and the city fish is the squid. It is therefore unlikely that anyone was surprised when, on July 18, a group of Hakodate residents made an official announcement regarding plans to create a giant robotic squid for the city.

The citizens' group, called "Robot Festival in Hakodate," aims to create a new symbol for Hakodate, one of the leading tourist destinations in Hokkaido -- and what better symbol than a giant robotic version of the city's favorite creature?

Members of the group include university professors specializing in robotic engineering, who will work to incorporate cutting-edge technology that will allow the robot to be controlled remotely via the Internet. Development will be led by Hitoshi Matsubara and Hidekatsu Yanagi, information architecture professors at the School of System Information Science at Future University-Hakodate (FUN). Matsubara will handle the robotics research and development, while Yanagi will handle design. Students from the university, along with Hakodate high school teachers and students and others in the local manufacturing industry, will contribute ideas in brainstorming sessions.

The group has chosen "light" as the design theme for the robot -- a choice based on the night view from Mt. Hakodate, a popular local tourist attraction where visitors can marvel at the twinkling lights of the city and squid fishing boats offshore. In line with this theme, the entire body of squid robot will be covered in lights that blink as the robot moves. In addition, the robot will be equipped with a set of wireless receivers and will have its own homepage featuring a set of controls that allow remote users to move the robot's tentacles and eyes.

The developers plan for the robot to stand 5 meters (16 feet) in height. After an intial 1.5-meter prototype is completed this November, work will begin on the larger final version, which the group aims to unveil in a parade at the Hakodate Port Festival in the summer of 2007.

Masao Fujii, chairman of the citizens' group, says, "We hope to create a high-quality robot that attracts a lot of attention and makes people want to come to Hakodate."

The total cost of the robot is expected to be somewhere in the 30 million yen range (US$250,000). The group hopes to cover much of that cost with membership fees, so they are now recruiting members.

Japan incarcerates invading turtles

19 Jul 2006

Recently Japan has seen a dramatic increase in the number of news reports concerning foreign turtles on the loose. Hardly a day passes without a reported capture, leaving one with the impression the country is under full-scale invasion by an army of rogue turtles. The culprits are predominantly common snapping turtles (Chelydra serpentina) and alligator snapping turtles (Macroclemys temminckii), both of which find their way from the Americas to Japan as pets. Authorities are responding aggressively, incarcerating the miscreant terrapins and publishing their mugshots in the media. The photo below shows some of the most recent detainees.

Face to face with high-tech medical devices

13 Jul 2006

The International Modern Hospital Show 2006 is being held from July 12 to 14 in Tokyo (Tokyo Big Sight), where nearly 400 companies have gathered to showcase the latest in healthcare-related technology. The theme of the show is "Reliable Health, Medical Treatment, and Care -- Aiming for High Quality Service," a theme whose success evidently depends on high technology. Below are photos (via Impress Watch) and explanations of a few of the devices appearing at the show. Despite appearances, these fellows are here to help.

The first photo shows a patient simulator developed by IMI Corporation and Paramount Bed Co., Ltd., a system consisting of a monitor connected to a sensor-laden mannequin whose physiology changes realistically according to the treatment it receives. Great for training future medical professionals. Great for your haunted house, too.

The next photo shows a transnasal endoscope developed by FUJIFILM Medical Co., Ltd. and Fujinon Toshiba ES Systems Co., Ltd. Surveys show that 90% of patients who have experienced endoscopy think it is more comfortable to enter through the nose (as opposed to through the mouth or anus). I hope the expression on this guy's face is no indication of his comfort level.

The next photo shows Muu Socia 3.0 (left), a cute cyclopean teardrop-shaped "communication support" robot developed by ATR and Systec Akazawa. The robot is designed to serve as a social mediator that livens up the communication between care giver and care recipient. Muu Socia has voice recognition, voice synthesis, speech processing and face recognition capabilities. And it starts bouncing around when something obstructs its view (watch the 5-second video (WMV)).

Pictured on the right is a home appliance control robot developed by RayTron Co., Ltd. Voice recognition capabilities allow patients to operate their home appliances by remote control. It looks sort of like an owl.

Aurora on demand

11 Jul 2006

Aurora generatorResearchers have developed the next best thing for would-be aurora gazers unable to make the trip to a near-polar location -- an aurora generator. The device was developed by Professor Shigeyuki Minami from the Graduate School of Engineering at Osaka City University, who worked with real estate developer Iida Sangyo Co., Ltd.

Beginning August 1, Iida Sangyo plans to fire up the device as the main attraction at its Enoshima Island Spa ("Enospa"), affording visitors the extra luxury of gazing at the aurora while lounging poolside on the second floor.

The aurora is generated within the belly of the machine, where a near-vacuum state is maintained. Electrons collide with oxygen and nitrogen to create colorful light in the same way that naturally occurring auroral light is generated in the earth?s upper atmosphere. One side of the device is made of transparent acrylic resin, allowing viewers to admire the beauty of the artificial aurora contained within. The aurora generator measures 2.2 (H) x 2.8 (W) x 1.4 (D) meters (7 x 9 x 5 feet), though the company claims to have engineered prototypes as large as 3 x 3 meters.

Aurora simulators in the past have relied on techniques such as laser beams that create aurora-like effects, while devices that have relied on electrical discharge in a vacuum have been very small. In addition to being larger and more "real" than previous devices, Iida Sangyo's device does not simply light up -- it emits a shimmering curtain of dynamic multi-hued light consisting of as many as 11 colors.

The company has not revealed exactly what technology is at work in the device.

Super-sharp lasers to boost disc capacity tenfold

28 Jun 2006

Laser donutResearchers at Kyoto University have developed new semiconductor laser technology that allows the shape of beams to be tailored freely and that can output beams up to 10 times more compact than existing beams ? a development that could lead to a tenfold increase in the storage capacity of optical discs. Research results were published in the June 22 edition of British science journal Nature.

The Kyoto University group, led by professor Susumu Noda, worked with Kyoto-based Rohm Co., Ltd. and the Japan Science and Technology Agency (JST) to engineer layers of photonic crystals consisting of tens of thousands of small holes, which were incorporated into 0.5 mm x 0.5 mm semiconductor chips. The photonic crystal layer works as an optical resonator, with each individual hole functioning as a tiny mirror that causes the light to resonate in the semiconductor until it is emitted as laser light. The result is a laser beam with a diameter up to 10 times smaller and with properties different from those of conventional semiconductor lasers.

According to the researchers, these new semiconductor lasers were able to produce a range of beam patterns while maintaining stable single-mode oscillation. The ability to control the oscillation direction of light in this way could lead to the development of compact lasers capable of producing diverse beam patterns on demand, such as hollow beams (with cross-sections that look like donuts), concentric hollow beams (donuts within donuts), and other shapes that have heretofore been impossible to form.

Controlling the oscillation direction of light also means that lasers can be focused into ultra-thin beams, enabling a tenfold increase in the density of data storage on discs without changing the wavelength of the laser. Using blue lasers such as those used in Blu-ray disc technology could lead to DVDs with hundreds of gigabytes of capacity.

Potential applications are not limited to ultra-high density storage media. Ultra-thin, hollow beams could be used as "tweezers" for trapping and moving microscopic particles, which could bring a new level of precision to molecular-level processing and fabrication. Hidemi Takasu, Rohm's research director, says, "In addition to seeing our research applied to next-generation DVD technology, we hope it can be applied to imaging technology that uses lasers to project precise images directly onto the human retina."

Video of Indonesian coelacanth

27 Jun 2006

A portion of the Indonesian coelacanth video shot several weeks ago has been made public.

The news report states that while more than 200 coelacanth finds have been documented off the coast of southern Africa, only 4 of the Indonesian variety had ever been confirmed before the Aquamarine Fukushima team caught theirs on video last month. According to the group's coelacanth web page, the researchers this time were able to capture a total of 7 coelacanth on video during the period from May 30 to June 5, as follows:

- May 30 (8:00 to 9:00 AM): Successfully videotaped an Indonesian coelacanth off the northern coast of Sulawesi, at a depth of 170 meters in 17 degrees Celsius water. Length of video is 5 to 10 minutes.

- May 31 (approx. 7:30 AM): Videotaped 2 more coelacanth in the same cave where the first coelacanth was videotaped.

- May 31 (approx. 10:00 AM): Videotaped another coelacanth in a different cave located at a depth of 180 meters.

- June 4 (approx. 6:40 PM): Videotaped 3 coelacanth over the span of 2 hours at a depth of 150 meters in the same area.

Beginning July 13, Aquamarine Fukushima will hold a special exhibit dedicated to the mystery of the Indonesian coelacanth, featuring video of the fish shown on a 65-inch plasma screen. The exhibit will run for an unspecified period of time.

Kawasaki BULLDOG to sweep Cambodian landmines

23 Jun 2006

Kawasaki's BULLDOGOn June 21, Kawasaki Heavy Industries announced plans to send its BULLDOG landmine clearing system to Cambodia, where it will be put to the test in the field. The BULLDOG system, which employs Kawasaki's robotic remote control and electronic control technology, has undergone some upgrades after conducting mine clearing operations in Afghanistan in 2004 and 2005.

By conducting test operations in Cambodian minefields, Kawasaki hopes to gather data that will help them develop a BULLDOG system well-suited to the local vegetation, soil conditions, and terrain. As was the case in Afghanistan, the operations are financed by a grant extended by the Japanese government.

The BULLDOG system consists of three parts: (1) the MINE DOG, a mine-detecting vehicle equipped with mine detection sensors and a variety of cameras, (2) the MINE BULL, a mine-clearing vehicle equipped with a drum that drills the earth to excavate and detonate mines and a mechanism to collect waste products, and (3) a system of devices for remote control and operation.

Relying on an 8-channel system of mine detection sensors that automatically adjust their height with respect to uneven terrain, the MINE DOG can detect anti-personnel mines and unexploded bombs underground. A camera mounted on top of the vehicle detects trip wires and mines scattered on the ground surface. Sensor data is analyzed using software developed by Kawasaki, which allows operators to distinguish mines from objects such as rocks or cavities in the soil. For the tests in Cambodia, Kawasaki added features to help the MINE DOG deal with vegetation, as well as features to improve mobility on soft ground.

The MINE BULL detonates anti-personnel mines by means of a high-speed digging drum that turns the soil in front of the vehicle. The vehicle's excavation depth monitor, GPS antenna, and route-monitoring cameras ensure steady digging and forward motion, and a system of magnets extract waste materials that typically slow down the safety inspections that follow mine clearing operations. To deal with Cambodia's sticky soil, Kawasaki added a system of brushes to prevent soil buildup and mobility-enhancing features similar to those added to the MINE DOG.

The MINE BULL will be shipped to Cambodia in June, and work will begin in a minefield near Siem Reap in July. The MINE DOG will be shipped in August, and it will go to work beginning in October.

Kawasaki aims to use the data obtained from these tests to quickly develop a BULLDOG system well-suited for the Cambodian landscape, which they hope will make a valuable contribution to international demining activities that involve the Japanese government and international NGOs.
