Essential Components Spa days and hospital stays: Panasonic’s new robotic fleet Everything from hospital visits to hair washing will soon go hightech. Panasonic announced the development of HOSPI-Rimo, a new communication assistance robot for people in hospitals. It also announced changes to its Hair Washing Robot and RoboticBed. Panasonic showcased prototypes of all three systems at the 38th International Home Care and Rehabilitation Exhibition in Tokyo from 5-7 Oct. HOSPI-Rimo uses the same autonomous technologies as its cousin, the HOSPI bot, which delivers medication automatically. It has a hybrid mobility function that lets the robot move through autonomous sensing or via remote control. Using HOSPI-Rimo’s High Definition Visual Communications System, patients can have smooth two-way conversations with doctors or loved ones. The Hair Washing Robot has been developed using Panasonic’s robot hand technology and can complete the entire process of hair washing automatically: wetting, shampooing, rinsing, conditioning and drying. Three-dimensional pressure-control technology lets the washing arms move over a wider range of the head. Using an advanced touch-panel interface, the user can even specify the spot to be washed, massaging pressure and washing mode. The RoboticBed combines the technologies of an electric care assistance bed, electric wheelchair and existing Panasonic robot technologies. People can move between the bed and the wheelchair on their own with the help of a common platform for all parts of the RoboticBed, a new tilted wheelchair restoration and separation function, and a user-friendly interface. The RoboticBed was first introduced in 2009.
The patch with a pulse on your health The Naval Postgraduate School in Monterey, Calif., is aiming to use technology to accelerate the delivery of medicine to the battlefield. Led by Alex Bordetsky, an associate professor in the school’s Department of Information Sciences, the concept would use networked sensors, along with unmanned air and ground vehicles, to detect medical issues and then transport medication to the patient. Perhaps even more impressive: Bordetsky predicts the technology could be on the battlefield in five to seven years.

The idea relies on devices called nano patches, developed by the Massachusetts Institute of Technology, that adhere to a solder or to a combat uniform. If a soldier is wounded, the device monitors vital signs and then relays the extent of the injury to a doctor, who could be located anywhere in the world. Unmanned ground vehicles would arrive at the injury and establish a data link or, if robust enough, move the patient to a safer location.

Homayoon Kazerooni, professor of mechanical engineering, had been working on robotic exoskeletons with his team of researchers since last fall. He and Whitney both hope the technology is more widely available soon. “This technology can be accessible to a large number of people, and that is our mission,” Kazerooni said in a press release. “We’re telling the community that this is possible.

According to a 2010 International Federation of Robotics study, the latest year for statistics, service robotics is a $13.2 billion industry.

cation, for example, or how long it took it to pick up certain things,” he says. Having a robot in a home setting is useful since it’s a very controlled environment, Jones says. “It becomes an assistant to the caregiver,” says Jones. It could also become a feedback mechanism for either talking to the individual or providing some other feedback on how well they’re doing today. And it can be a sensor in the environment, so it’s able to observe behaviors.” The robot could also be a social device,” says Jones, “somebody to confide in.”

At-home helper Jeff Beck, president of iRobot’s home robots division, says people get so emotional about their connection with the company’s flagship product, the vacuuming Roomba, that he’s received multiple letters a week since he started with the company about two years ago. “It really set me back a little,” he says. “I started getting letters from people talking about their robotics in the first person. They give them names; they adopt them almost as family members.” Beck notices that the younger generation tends to respond to the robots by having fun with them, say by filming cats riding around up top and posting it to YouTube, but the company’s older clients form a strong emotional bond with the company’s Roomba, robotic mop Scooba, pool cleaner Verro and gutter cleaner Looj.
Scan this barcode with your smartphone to see the most popular YouTube video of iRobot’s Roomba. A cat taking the product for a spin has more than 6.6 million hits on the website.
IRobot’s Roomba robotic vacuum cleaner is its most popular domestic robot to date, having sold more than 6 million copies. Photo courtesy iRobot Corp.
“You get people who are wounded veterans or elderly people and they’ll write letters saying, ‘Because of Roomba and Scooba, I’m able to live in my home more comfortably. I don’t have to worry about pushing a vacuum cleaner or mopping my floors.’ Those types of things happen all the time.” The company, which gained about 55 percent of its 2010 sales from its domestic robot division versus military ground vehicles, is successful in the still burgeoning field of domestic robots by focusing on practicality, Beck says. “Our primary business, different than a lot of other companies, is that we’re really looking to develop and deploy practical robots that are useful and do lots of jobs that people don’t like to do every day in their homes,” Beck says.

Robotic Houses — continued from Page 15 Although right now a lot of these home features require human interaction, Balsman believes the technology is currently on the cusp of becoming truly autonomous. “Honestly, in my opinion, that’s where we’re at right now,” he says. “What you’re seeing and what you’re starting to see the focus of most of the automation companies is to truly make it automated, where it’s truly a matter of scheduling or where the house is interactive on its own attributes. That’s the next step.” With current technology, the push of a button can control anything that’s tied into the Savant system, including elevators and even a quirky chandelier in the winning home that flashes to show that the bathroom is out of toilet paper. “But it’s still by the press of a button,” Balsman admits. “So the next step is really getting the house to interact on different scenarios or different themes, so to speak.” Right now there are a few fairly standard automated features, like blinds and shades that adjust to outdoor lighting and weather or turning on and off a pool’s features. In the future, the end user could input his feedA child’s bedroom from the Electronic House Home of the Year winner.

A world of home robots
STATE OF THE ART
Though Michigan is known more for its automotive industry, it also has another market cornered: robotic litter box cleaning. Made by Automated Pet Care Products Inc., the Litter-Robot takes care of the kitty litter scooping for days, sensing when the cat leaves the litter box and then cleaning it through a rotating motion. Warning though: The sensor isn’t strong enough to sense kittens and small cats and could send them tumbling if left automatic mode.
Nashua is home to VGo Communications, makers of a robot that may one day join the workforce. The telepresence robot VGo can act as a remote professional or student, which it did for a ninth grader in Knox City, Texas, this year whose immune system was too compromised to attend school.
Bedford, Mass. The headquarters for iRobot Corp., the Boston metro area has churned out millions of robotic vacuums in the company’s flagship product, the Roomba. Other current at-home helpers include a floor washer, pool cleaner and gutter clearer.
Berkeley, Calif. Researchers at the University of California Berkeley are working hard at making a robot that performs one of the most monotonous chores: the laundry. The robot currently only folds items — pretty slowly at that — but in the future the team aims for it to complete the entire laundry process.
Menlo Park, Calif. Employees at Menlo Park company Willow Garage tasked a robot with a dream job for any couch potato that doesn’t want to miss a second of Monday Night Football® — a robot that will fetch you a beer. The company used its PR2 and programmed it to get you specific brands of beer out of the fridge, and it’ll even tell you if your favorite brew has been dried up.
Under the leadership of Charles Kemp, Georgia Tech’s Healthcare Robotics Lab has worked since 2007 to develop robotic systems that assist the elderly or disabled with manipulating their environments.
The perfect combination of helper robots or telepresence tools may not be in every home just yet, but they are scattered across the globe, coming from a variety of companies in different parts of the world. Here’s a look at a collection of places making robots right now that could be our future personal assistants.
Örebro, Sweden Örebro University is spearheading the panEuropean program ExCITE (Enabling SoCial Interaction Through Embodiment), which is monitoring the use of telepresence robots in individual homes and in assisted living spaces in a multi-country, multi-year study.
Jinan, Shandong Province, China At the Dalu Robot Restaurant in Jinan, robots have replaced the front-of-the-house staff, serving as receptionists, hosts and even waiters. Though human cooks still handle the food in the kitchen, tracked robots riding bicycles offer patrons drinks and dishes on their own.
Stuttgart, Germany Stuttgart’s claim to robotic fame is the development of the Care-O-bot, created by the Fraunhofer Institute for Manufacturing Engineering and Automation. The mobile household aid was created in 1998 and works as an “interactive butler,” according to the institute.
Tokyo, Japan Tokyo’s National Institute of Advanced Industrial Science and Technology, or AIST, was the birthplace of Paro, the robotic baby harp seal tasked at having a soothing effect on hospital patients and nursing home residents. The product is now sold in the U.S. by PARO Robots U.S. Inc., headquartered in Itasca, Ill., and in Europe via the Paro Clinic in Odense, Denmark.
Hong Kong, China Pardesia, Israel Pardesia is home to retailer Friendly Robotics, which supplies products to the United States, Europe, Australia, New Zealand and South Africa. The company released Robomow, its robotic lawn mower, in 1998. It has also made robotic vacuum cleaners and golf carts.
Hong Kong holds the headquarters of WowWee Group Ltd., a company that, in addition to a long line of toys, makes the Wi-Fi enabled Rovio, a mobile webcam that lets the user interact with its environment through audio and video. Coupled with a TrueTrack Room Beacon, the robot can navigate waypoints, keeping watch over the premises.

ome new sales figures have come in, and you need to discuss them
with your team. Problem: They’re in Seattle and you’re on vacation in the Bahamas. Solution: Call up the office manager and say, “Get the robots out of the closet; we need to have a team meeting.” Not long after, you’re able to control a robot via long distance, looking at the charts with its camera, talking with your colleagues via its speakers and microphones. When the meeting breaks up, you’re able to walk to the kitchen with one colleague to conclude a bit of unfinished business. When the meeting is all done, the robot goes back in the closet, and you signal the waiter for another drink. Farfetched? Not at all. Although there are still a few kinks to work out, it’s already been done.
Google’s robots Researcher Katherine Tsui of the University of Massachusetts Lowell worked with colleagues Munjal Desai and Holly Yanco and Google Inc.’s Chris Uhlik to test how telepresence robots could function in an office environment. In a study conducted in the summer of 2010, the researchers studied the various ways that telepresence robots could be used at the search engine giant. Although Google has sophisticated video conferencing equipment, it didn’t yet have robots, Tsui says (Google co-founder Larry Page had one, but it was for his personal use). The top half of Hugo, a VGo Communications telepresence robot, has been augmented with a light-up LED tie used to indicate the robot’s current status. The driver can be seen on Hugo’s screen. Photo by Adam Norton.
“It’s a novel thing, people like to use it. It’s just going to be a few years before they become really pervasive and people use them instead of video conferencing,” she tells Mission Critical. However, “there’s a lot of talk about how much work gets done in social contact. That’s where being outside of a standard video conference room really helps.”
In a paper presented at the 2011 HumanRobot Interaction conference in Switzerland, Tsui and her partners noted, “commercial telepresence robots can be described as embodied video conferencing on wheels. These new telepresence robots provide a physical presence and independent mobility in addition to communication, unlike other video conferencing technologies.” The researchers introduced two robot models to Google: the QB, built by Mountain View, Calif.-based Anybots, and the VGo, built by VGo Communications of Nashua, N.H. The QB stands a bit over six feet, has three microphones, two cameras and one speaker. The VGo is four feet tall, has four microphones, one camera and two speakers. The researchers placed those robots in a variety of team meeting settings. In some, the teams were “hub-hub,” meaning most of the
Hugo, an augmented VGo Communications telepresence robot, is being driven remotely and being used to walk alongside a colleague, actively participating in a mobile conversation.

Elementary diagnosis, Dr. Watson Q&A Martin Ford is the founder of a Silicon Valley-based software development firm. His book, “The Lights in the Tunnel: Automation, Accelerating Technology and the Economy of the Future,” explores questions of how accelerating computer technology contributed to the current global economy and whether more disruptive impacts lie ahead. In a recent opinion piece for The Washington Post, Ford discussed how IBM’s supercomputer, Watson, could improve health care. IBM announced in September that it would team up with insurance company WellPoint to use Watson as a sort of automated clinician’s assistant. In the article, Ford argues that Watson’s new role in health care could mean big changes in healthcare procedures, costs and jobs. And the impact of the technology reaches far beyond the world of medicine.

It’s going to be a question of whether populations of patients will be comfortable interacting with the robots in terms of actual care where they actually get touched by the robots and things like that. It may take a little more time. Initially, I think it’s going to be more behind the scenes.

A University of Missouri study estimates that the United States could experience a shortage of about 44,000 family practice and general internists over the next 20 years. Compound to that issue is that doctors are also cutting hours back, due to concerns of exhaustion on the job. The Journal of the American Medical Association estimates that average work hours for doctors have decreased from 55 to 51 per week from 1996 to 2008 — the equivalent of losing 36,000 doctors in a decade.

A stitch in time
The beginnings of the robotic surgery business found two companies pitted against each other for market dominance. After years of closely following one another in achievements and a series of patent lawsuits, Computer Motion and Intuitive Surgical Inc. found a creative solution to their problem.
Computer Motion, an emerging robotic surgery company, is founded in Goleta, Calif.
Aesop 1000, the first robotic surgery product by company Computer Motion, is created. Much like a third arm for a surgeon, the robot can hold an endoscopic camera during laparoscopic surgery, an incision type that uses a small keyhole-sized entry point. It is the first robotic surgical aid to gain FDA certification.
1990 The Stanford Research Institute International gets funding by DARPA to work on a robotic surgery system capable of operating remotely on soldiers on the battlefield.
1995 Also created by Computer Motion, the Zeus Robotic Surgical System, a threearmed device attached to the side of an operating table, is demonstrated.
Computer Motion sues Intuitive Surgical on eight counts of patent infringement.

As a solution to the lawsuit, Computer Motion and Intuitive Surgical merge and phase out the ZEUS robotic system. The companies agree to headquarter in Sunnyvale, Calif., the location of Intuitive Surgical.
Zeus gains FDA approval.
9 9 5
The da Vinci Surgical System, by Intuitive Surgical, a company formed out of the Stanford Research Institute International, gains FDA approval. Originally called Lenny, the systemâ€™s 3-D imaging ability earns it a unique spot in the emerging field of robotic surgery.
The FDA approves the da Vinci system for prostate surgery.
1998 The Zeus robotic system performs the first fallopian tube reconnection surgery as a part of a clinical trial at the Cleveland Clinic.
1998 1996 Computer Motion releases the Aesop 2000 model, with added voice control.
The Leipzig Heart Centre in Germany performs the first robotically assisted heart bypass surgery using the da Vinci Surgical System.

based Alion Science and Technology developed the 3-D model for the robotic limb based on ultrasound images. Using a syringe, doctors will be able to implant wireless sensors into a patient’s arm to optimize control of a prosthetic. This will also require doctors to find working nerves and muscles they can integrate from the injury itself.
“It’s amazing,” says Martin Ford, computer engineer and author of “The Lights in the Tunnel: Automation, Accelerating Technology and the Economy of the Future.” “It goes far beyond what any one person would be able to do. Making sense of that [machine learning], that’s probably going to ensure that a lot of things that fall through the cracks are going to be considered in the diagnosis. My hope for it is that it’s going to evolve into something pretty standard.”
Paging Dr. Watson Some of the robots now being used in hospitals got their start on a more public platform. In September 2011, IBM announced a partnership with WellPoint Inc. to bring its Watson computer system to “serve as a clinician’s assistant,” says Christine Vu of IBM’s research department.
Ford, who has not worked on Watson himself, says doctors at first will likely be reluctant to rely on Watson too much. Over time, the autonomous system will build a track record of information gathering and diagnostic assessment. Read more from Martin Ford about Watson in Q&A on Page 27.
Wired for care The primary use of robotic surgery systems, like Intuitive Surgical’s da Vinci Surgical System, in urology is for treating prostate cancer. Patel says 80 percent of prostatectomies in the United States are done with the use of a robot. He says much of the increase is due to patient preference. “They want to have robotic surgery,” Patel says. “It’s based upon the outcomes that are being published.” By using tiny incisions during surgery, the robot allows for less blood loss during surgery and faster patient recovery. Da Vinci and other robotic surgery platforms provide surgeons with enhanced vision, precision, control and dexterity. “It has instrumentation, so we have seven degrees of freedom,” Patel says. “It looks like you’re inside of the patient when you’re operating.” Robots are now more commonly being used for surgical procedures in gynecology and general surgery. Approximately half of all myomectomies, the surgical removal of fibroid tumors in the uterus, are performed with a da Vinci robot. General surgery uses

“All hospitals these days will have a large volume of prostate cancer procedures or gynecological procedures with a robot,” Patel says. “A lot of the procedural problems have gone away.” In cardiology, da Vinci is commonly used to treat mitral valve prolapse, when a heart valve does not properly seal, and coronary artery disease, a narrowing of the blood vessels that supply the heart. Cardiac patients who choose da Vinci surgery to repair their mitral valve have an average in-

“Autonomy can be applied at very different levels with very different behaviors,” Jordan says. “The trick is to apply that appropriately so that the safety and the efficacy are appropriate for what you’re trying to accomplish.” It seems robotic surgical systems have nowhere to go but up as the demand for doctors grows, especially in primary care. As more and more physicians look to lucrative specializations and big-city hospitals for employment, patients with chronic conditions such as diabetes or obesity get left in the lurch. Ford acknowledges there is a serious problem of physician shortages in rural areas and less glamorous fields of medicine. This could lead to a new type of relationship between robots and healthcare workers in which automated systems are responsible for much of the diagnostic and procedural work in patient care, while a person is still involved with the more “human” aspects of health care like bedside manner. “You already see that to some extent with nurse practitioners, but of course we also have a shortage of nurses,” Ford says. “So I think there’s an opportunity for another type of professional that’s maybe specifically trained to work with these diagnostic systems, and they might still operate under the division of doctors.”

On the procedural side, robots are highly involved in routine hospital work. These systems make deliveries within hospitals and
hooked up to a gurney next to the patient. In the Dallas/Fort Worth area, 11 hospitals already use telepresence robots for consultations between doctors and patients. The interface allows doctors to use digital images and face-to-face interactions with patients to help with everything from routine checkups to making crisis health decisions. For more immediate care, the robot also has a special stethoscope that allows the doctor to remotely hear a patient’s heartbeat. But there is a long way to go between the exam room and the emergency room. “Telepresence surgery is something that’s not real yet, but the remote surgery is something that we’re working on,” Patel says. Patel says the next step in making robotic telepresence surgery a reality is to integrate imaging systems during surgery.

Crossing the valley Examples of not-quite-there robots abound. Professor Hiroshi Ishiguro of Osaka University is famous for building Geminoid, a humanoid robot that looks just like him. That has since expanded into several semilifelike robots, manufactured by Japan’s Kokoro Co., which builds robotic dinosaurs and rents out “Actroids,” human-like female robots that can serve as restaurant greeters or office assistants.
Ishiguro says that one day people could communicate remotely using their robot doubles, using them like sophisticated cell phones. Scientists at the National Taiwan University of Science and Technology recently unveiled a singing robotic head that can read music and react to facial expressions. “Robots with various human-like facial expressions and conversation capabilities are useful for attracting attention from human beings and, therefore, are especially suitable for applications involving robot and human interaction,” Chyi-Yeu Lin and his researchers wrote in a paper. Although he wrote later in the paper that “people love robots and they like to watch performances of these robots,” many Internet reactions were less kind. One website described the singing, rubbery head as “creepy” and another described it as “a melodious abomination.” Austrian researchers at the University of Salzburg recently undertook an investigation of what people would like to see in a service robot, particularly one designed to operate in a public space. They had assumed that respondents would prefer an anthropomorphic robot design, but that was not the case. “In contrast to our assumptions, the results

showed that the participants did not prefer a merely anthropomorphic design for an interactive urban robot, but a combination of anthropomorphic and functional elements,” they wrote in a paper. “Human cues like eyes and a mouth turned out to be essential in the imagination of these potential users in order to know how to interact with a robot.” The end result — which the researchers said needs more fine tuning — turned out to be a one-armed cat-like robot riding on a wheel.

He explained, “I am very satisfied with the system as a whole. I think it does exactly what it says on the tin. We are making savings in terms of labor costs as we have been able to free up porters to undertake other tasks and focus more on patient care. No jobs have been lost as a result of their introduction and the unions are fully behind the project. There is also the benefit of reducing the chances of spreading infection as they operate behind the scenes.” Existing on-site engineers, in tandem with JBT Corp. specialists, are carrying out maintenance of the vehicles. The automatic vehicles use laser navigation technology to find their way around the facility and are equipped with front and rear electronic obstacle detection bumpers to prevent collisions.

‘The Stepford Wives’ First a 1972 book and then made and remade into movies in 1975 and 2004, “The Stepford Wives” is a satirical look at the subservient status of women in the town Stepford, Conn. New-to-town New York City photographer Joanna Eberhart is perplexed by the women of Stepford, who are always perfect in appearance and are at their husbands’ beck and call. The women delight in grocery shopping, cooking and household chores. Joanna becomes convinced that the housewives are actually robots, created to perfection in the Stepford men’s club. In a jarring scene near the end of the 1975 version of the movie, Joanna is coerced into robotic wife Bobbie’s house, a formerly smart women that suddenly turned vapid since moving to Stepford. Bobbie offers to perk her up with coffee instead of worrying about her missing children. Joanna cuts her own hand and then stabs Bobbie, who doesn’t bleed, proving she is a robot. Bobbie grabs the knife out of her hip and puts it back in place, all the while stuck in an eerie speech loop, “How could you do a

thing like that? I was just going to give you coffee. I thought we were friends.” Later in the men’s club, Joanna finds her own robot duplicate, which, the film suggests, kills Joanna. The robot continues on in her place, grocery shopping to its heart’s content.
‘Surrogates’ There have also been several movies and books about the use of telepresence robots to expand human experience. In the 2009 thriller “Surrogates,” Bruce Willis must investigate a murder in a time when people stay home and only interact through robotic versions of themselves, versions that are
