Researchers at Toshiba have developed a talking robot that functions as a voice-operated universal remote control for multiple home appliances. The 2.3 kilogram (5 lb), 21 x 27 centimeter (8 x 11 in) prototype robot, named ApriPoko, learns how to operate various remote controls by watching and asking questions. ApriPoko sits in the living room and waits for you to use a remote control. When its sensors detect infrared rays emitted by a remote, the robot speaks up: “What did you just do?” it asks. Tell ApriPoko what you did (”I turned on the stereo” or “I changed to channel 321,” for example), and it commits the details to memory. Then, next time you want to turn on the stereo or change the channel, simply tell ApriPoko and it transmits the appropriate IR signal directly to the device. The prototype robot is still in the development and testing phase, but Toshiba hopes to have a viable product soon.

Researchers at the University of Tokyo have developed a smart video goggle system that records everything the wearer looks at, recognizes and assigns names to objects that appear in the video, and creates an easily searchable database of the recorded footage. Designed to function as a high-tech memory aid, these “Cyber Goggles” promise to make the act of losing your keys a thing of the past, according to head researcher professor Tatsuya Harada.

Cyber Goggles are equipped with a compact camera that feeds video to a computer worn on the user’s back. The computer records the footage and relies on ultrahigh-speed image recognition processing software to analyze, name and file the objects that appear in the video. Later, when the user types in a keyword to search for a particular item, the corresponding video plays on a tiny LCD screen attached to the right-side lens, helping the user remember the location of the item in question.

In a demonstration at the University of Tokyo last week, 60 everyday items — including a potted begonia, CD, hammer and cellphone — were programmed into the Cyber Goggle memory. As the demonstrator walked around the room viewing and recording the various objects, the names of the items appeared on the goggle screen. The demonstrator was then able to do a search for the various items and retrieve the corresponding video.

In addition to functioning as a memory aid for the elderly, Cyber Goggles have a number of other potential uses, says professor Harada. For example, the image recognition processing technology can be used to sift through enormous amounts of video in search of specific images. It might also help in the development of robots with human-like abilities, he says.

For those who believe laughter is the best medicine, now there is a way to measure the dosage. Researchers at Kansai University have developed a machine that can scientifically measure the quantity of a person’s laughter, as well as distinguish between the real and the fake.

The laughter measurement system, which the researchers say will help scientists conduct more detailed research into the physiological effects of laughter on the immune system, relies on a series of electrode sensors that monitor the tiny amounts of bioelectricity generated by certain muscles that flex when you chuckle. The sensors, which attach to a person’s cheeks, chest and abdomen, take 3,000 measurements per second. Sensor data is relayed to a computer, where it is analyzed by special software that determines the nature of the laugh and assigns a numerical score based on the quantity.

The laughter quantity is expressed in terms of “aH” — a unit of measurement developed by the research team. According to chief researcher Yoji Kimura, a Kansai University professor, 1 second of explosive laughter amounts to 5 aH.

The system distinguishes between real and fake laughter by closely monitoring the movement of the diaphragm — the thin sheet of muscle extending across the bottom of the rib cage, which separates the chest organs from those of the abdomen. According to Kimura, the diaphragm does not vibrate significantly when a person pretends to laugh, even when the person’s voice and facial expression appear genuine. On the other hand, when one laughs at something they truly find funny, the diaphragm generates 2 to 5 distinct vibrational waves per second.

At Kansai University on February 21, the researchers publicly demonstrated the system by measuring the laughter of a 30-something-year-old woman and her 5-year-old daughter as they watched a performance by Yoshimoto comedians. The mother, who apparently found no humor in the comedy routine, experienced only slightly more than 0 aH of laughter, while her amused daughter experienced a hearty 42 aH.

The researchers, who spent over a year developing the system, are aiming to create a portable version of the system for use in health and entertainment devices.

As long as oil is transported by sea, accidental spills will remain a threat to the marine environment. When an oil spill occurs, the cleanup response must be quick in order to minimize the environmental and economic impact. To help speed up the response, researchers at Osaka University are developing an autonomous marine robot that can track down spilled oil and provide real-time location data.

SOTAB 1 (Spilled Oil Tracking Autonomous Buoy 1) is a 110-kilogram (243 lb.) GPS-equipped robot that measures 2.72 meters (9 ft.) from top to bottom and 27 centimeters (11 in.) in diameter. It has imaging sensors that can spot floating globs of oil from a distance, as well as viscosity sensors that detect the presence of oil, and it includes a wind monitor, depth meter and water thermometer. When multiple robots are dropped into the water at regular intervals around an oil spill, they can provide a wealth of valuable data to cleanup crews and allow them to monitor a wide area.

Once in the water, SOTAB 1 begins searching for oil by reducing its buoyancy and diving underwater, where it trains its imaging sensors back up at the surface. When the robot sees something that looks like oil, it readjusts its buoyancy and floats back to the surface, using 4 fins to steer toward the oil slick. It then takes water samples and determines how much oil is present. As SOTAB 1 follows the oil around, it sends back real-time data about its location and the surrounding meteorological and oceanographic conditions.

Head researcher Naomi Kato, an underwater robotics engineering professor at Osaka University, says SOTAB 1 is still in the development phase, but he hopes to see it become commercially available in 2 to 3 years.

“We want to get the weight under 30 kilograms and extend the battery life to about 3 to 4 weeks,” says Kato, who began working on the robot in 2006. “We would one day like to see these robots become standard equipment on oil tankers.”

In recent years, Hitachi’s finger vein authentication technology, which identifies individuals by the unique pattern of blood vessels inside their fingers, has helped beef up the security of devices ranging from ATMs and cardless payment systems to computers and automobile ignition systems. Now this biometric technology is heading to the gym.

IT company Fukui Computer has unveiled a new line of networked exercise machines, called “medimo,” that are equipped with Hitachi finger vein readers. When users identify themselves with a simple press of the finger, the machines respond by automatically adjusting the weight resistance and seat position based on the user’s previously set preferences.

The machines also connect to a remote server to retrieve the user’s personal exercise data — including previous exercise records and stats, training regimens and calorie consumption data — which shows up on a touch-screen display. Users can then do their workouts based on this data, which is updated each time a machine is used, or personal trainers can refer to it when providing exercise advice.

Fukui, who unveiled the 12 new medimo machines on February 18, plans to begin selling them on April 1 for about 1.8 million yen ($17,000) each. The company is targeting fitness gyms, hospitals and welfare facilities, and is expecting to sell 2,000 machines over the next 3 years.

As hay fever season approaches, Tokyo-based weather forecasting company Weathernews, Inc. is deploying a 200-strong army of beady-eyed, ball-shaped robots nationwide to monitor the pollen situation.

The so-called “Pollen Robots,” which weigh 1 kilogram (2.2 lbs) and measure 30 centimeters (1 ft) across, consist of a monitoring unit housed in a spherical styrofoam shell. A pair of eyes glow 5 different colors — white, blue, green, red and purple — to indicate the level of Japanese cedar and cypress pollen in the air.

Two hundred hay fever sufferers around the country have volunteered to hang the Pollen Robots outside their homes, where they will monitor the air and send minute-by-minute reports over the Internet to Weathernews headquarters in Tokyo. The data will be used to update the company’s online pollen map.

Weathernews is forecasting higher-than-normal pollen counts this spring.

The Osaka-based Advanced Telecommunications Research Institute (ATR) has developed a crowd-monitoring humanoid robot that recognizes when people are lost and helps them find their way.

In a series of demonstrations conducted from January 22 to 24, a souped-up version of ATR’s Robovie humanoid robot monitored people as they passed through a 100 square meter (1,076 sq ft) section of the Universal Citywalk Osaka shopping center. Relying on data from 16 cameras, 6 laser range finders and 9 RFID tag readers installed in and around the area, the robot was able to watch up to 20 people at a time, pinpoint their locations to within a few centimeters, and classify each individual’s behavior into one of 10 categories (waiting, wandering, walking fast, running, etc.).

Whenever Robovie spotted people who looked disoriented, the child-sized droid wheeled up to them and asked, “Are you lost?” If so, the robot provided simple directions to the destination and pointed the way. If not, the robot proceeded to recommend nearby shops and restaurants.

ATR says the Robovie test is the first in a long series of robot-related demonstrations to be conducted at Universal Citywalk Osaka. This week, the company announced it was establishing a permanent base in the shopping center, which will serve as a real-world environment for testing new robot-oriented business ideas. In June, the company plans to start hiring out its machines to companies toying with the idea of employing robots.

Tokyo-based educational company Gakken is recalling 10,000 of their electronic talking Smart Globes following a rash of customer complaints about a mislabeled Taiwan. On the globes, Taiwan — a self-governing nation that split from communist China in 1949 during a civil war — is labeled as “Taiwan Island,” and the globe’s smart pen reader, which streams audio data about a nation’s geography, history and culture whenever you touch its location on the globe, identifies Taiwan as part of the People’s Republic of China.

Gakken had originally intended to use the standard labeling for Taiwan (as per the Ministry of Education’s specifications), but the Chinese factory based in Shenzhen apparently refused to produce the globes unless Gakken agreed to label Taiwan as part of China. Gakken agreed to the factory’s demands.

The company sold out their entire first shipment of 10,000 Smart Globes, which were released in Japan last August, but customer complaints flooded in, prompting a recall.

Interestingly, a note included in the box along with each Smart Globe explained that Taiwan’s name and data had been changed at the factory based on instructions from the Chinese government. However, at a January 10 press conference to announce the recall, Gakken said that they did not receive direct instructions to make the changes, and that they are investigating why the changes were made.

According to a Gakken press release announcing the Smart Globe recall, the company is reimbursing customers the full price of 29,400 yen ($270).

In a similar move, toy maker Takara Tomy also held a press conference on January 10 to apologize to customers and announce a recall of their smart “Talking Globe,” which — like Gakken’s Smart Globe — features a mislabeled Taiwan and was manufactured in China.

In an effort to accelerate the development of next-generation automobiles and robots, Toyota is turning to some of Japan’s top neuroscientists. According to a December 14 announcement, the automaker has teamed up with the Institute of Physical and Chemical Research (RIKEN) in a 20-year project aimed at researching the human brain and developing neurotechnology-based auto safety systems, sophisticated robots, and machinery that users can operate with their minds.

Toyota and RIKEN will conduct the brain research at the recently established RIKEN BSI-Toyota Collaboration Center, which will initially be staffed by 30 researchers, 5 of whom are from Toyota. The research will fall into three broad categories: (1) neuro-driving research, which focuses on the mental processes at work as drivers perceive, judge and react to the external environment, (2) neuro-robotics research, which focuses on how the brain processes information, and (3) mind-health research, which focuses on the physiology of the brain and nervous system and the relationship between the brain and physical health.

Through the neuro-driving research, which is expected to shed new light on how the brain works as drivers perceive obstacles and operate their vehicles, Toyota ultimately hopes to develop auto safety technology that can completely prevent all traffic accidents.

In addition, the automaker explains that the purpose behind the neuro-robotics research is to develop advanced robots that can interact more effectively with humans. Toyota, which sees robotics as one of its core businesses in the future, has been stepping up efforts in recent years to develop “lifestyle support” androids for use in nursing and health care. The company also believes the research will lead to the development of brain-machine interfaces that allow users to operate equipment by thought.

Toyota explains that the decision to pursue brain research is driven by an ever-increasing demand for more sophisticated automotive and robot technology. With a better understanding of the cognitive mechanisms underlying human feelings, thoughts and actions, the company reckons it can get a head start in the race to develop the cars and robots of the future.

On November 21, a group of small- to medium-sized venture companies based in western Japan unveiled an autonomous ladybug-shaped robot designed to clean public restrooms at highway rest areas.

The 1-meter (39-inch) tall, 1.35-meter (53-inch) long prototype robot — named “LadyBird” — is equipped with water tanks, brushes and other tools needed for heavy-duty scrubbing. Obstacle detection sensors allow the robot to safely perform its duties without running into people.

In addition to cleaning, LadyBird can engage in simple conversation with restroom users, thanks to microphones in its “antennae,” speech recognition capabilities and a voice synthesizer. The robot has access to the latest information about traffic conditions on nearby roads, which it can relay to anyone comfortable enough to ask.

The developers, who are building LadyBird for West Nippon Expressway Company Limited (NEXCO), aim to complete the machine by March 2009, and they hope to one day see it cleaning toilets at hotels and other institutions. Lady Bird robots are expected to sell for about 3.5 million yen ($30,000) each.
