Robotic bartender assembles personalized drinks, monitors alcohol consumption, and takes social mixing to a whole new level
You’re at a busy bar. You order your personalized cocktail through a smart phone app; a drink dispenser measures out the beverage according to your instructions and a Kuka robotic arm give it a shake (or stir), while another garnishes it with a slice of lemon; the made-to-order concoction is delivered to your waiting hand via a slick little ten-lane conveyor belt.

The ‘mixology system’ tracks your order from start to finish: a large display behind the bar shows you the number of drinks ahead of yours in the queue, the current wait time, and lets you know when your drink is ready to be picked up. It also shows you what’s popular to drink tonight among both the ladies and the gents in the crowd, and lets you influence drinking trends in realtime by incorporating your suggested tweaks on popular recipes.
This clearly isn’t your parents’ neighbourhood watering hole, but it could be your kids’ — or even yours if you are lucky enough to be at the After Hours event tonight in San Francisco. Welcome to , a bar for the ‘sense-able city’ of tomorrow.
Makr Shakr is one of MIT’s projects, where the goal is to study and anticipate how sensor technologies can inform and transform our built environments. The project’s creators say that it’s not about trying to replace bartenders with robots, or even about drinking; it’s about exploring the dynamics of consumption and social networks in the context of sensor and digital fabrication technologies. In other words, its a mini-lab for learning about how we, the social creatures that we are, might interact with each other and our environments in the sensor-augmented cities of tomorrow.
According to project leader Yaniv Turgeman, Makr Shakr was conceived as part research project, part art installation, part social experiment: ”It is a research platform aimed at the , where anyone can design, produce and influence culture. It’s also an installation meant to provoke and question our relationship with technology and creation … we’re experimenting with the idea of social co-creation and consumption.” Given Makr Shakr’s fundamental connection to crowdsourcing and social networks, it’s no wonder, then, that the project was invited to this year’s Google I/O event as a feature project.
As I write this article, Turgeman is busy with last minute preparations for Makr Shakr’s official launch at tonight’s Google I/O After Hours party, but I managed to track him down for a phone interview earlier this afternoon. He explained to me that point of the project was to take the phenomenon of and learn whether (and how) we can leverage it to socially create “bottom up culture”.
The SENSEable City Lab has many social and sensor networking projects at various stages of development (including elaborate plans for a project that will explore how social connectivity can be used to influence the production, distribution, preparation, consumption and recycling of food), but when Google first approached the lab about developing a project specifically for the 2013 I/O event, the team chose Makr Shakr because drinking is a social and relatively discrete (and therefor easy to parameterize) activity; in other words, it’s an ideal context for studying how people interact with digitally-mediated social networks.
“Drinking happens to be a very social activity,” Turgeman said. “At a bar, you’re looking to meet people. You might think ‘hey that’s a great drink I just invented’ and want to share it or iterate on it … by exploring the realtime behavioural dynamics in this situation, maybe we can learn something about how people interact with and influence each other’s consumption habits.”

Digital fabrication is an important theme at the SENSEable City Lab, which regularly partners with industry in order to contextualize researchers where they can conduct real-world experiments. The kind of personalized, just-in-time digital fabrication and delivery exemplified by Makr Shakr (the ‘third industrial revolution’ Turgeman refered to earlier in our conversation) is one that demands that big time players from the food and beverage sector take note. And some already have — in 2009 Coca-Cola launched , a touchscreen-operated beverage dispenser that offers more than 100 of the company’s brands in a single dispensing device. But the big idea of Turgeman’s project is not to study delivery systems for custom drinks, it’s to study how cultural memes are created and promoted, and this is surely of interest to major brands like Coke and Bacardi, which are the main sponsors of the project.
In this context, Makr Shakr takes personalized branding to a whole new level. Says Turgeman: “The magic moment will be watching the formation of a bottom-up bar culture, as we close the loop between co-curating and co-producing in real time.” It’s not hard to imagine that, if Makr Shakr one day goes mainstream, advertisers and big brands will want a piece of the action. But as top-heavy players in a bottom-up world, the question that lingers is, will we let them?

It’s not clear to me during our phone interview whether Turgeman sees the pun in his ‘bottom up’ approach to influencing drinking culture, but it does get me prodding him about the claims on the Makr Shakr website that the system promotes responsible drinking by allowing people to self-monitor their alcohol consumption.
While this feature won’t be operational during the Google I/O event (they are expecting a crowd of 5000+ and didn’t want to overextend the system tonight) Turgeman explained that, yes, Makr Shakr can be used to track a person’s alcohol consumption. There’s no breathalizer unit to blow into (too uncouth, I imagine, not to mention the privacy issues and ick-factor); instead the system estimates your blood alcohol levels based on weight and height information you provide when you install the app on your phone, and the number of drinks that the system has served you.
The Makr Shakr phone app displays your blood alcohol level over time in a chart, but it also uses three simple icons to tell you whether you are safe “to drive, to walk or to talk,” because, as Turgeman points out, numbers might be meaningless to you, especially after a few drinks. “Sometimes you think you’re safe to drive when you’re not. When you’re being social, it’s hard to keep track of how many drinks you’ve had,” says Turgeman, and since that data is so easy to capture, “it’s a no-brainer that of course we should let people know.” He also assures me that, as discretion is a must for bartenders, all data from the Makr Shakr app is anonymous (though users are able to share their age, gender, nationality, nickname and photo or avatar for social networking if they want to).
Though Makr Shakr will not demand that you turn over your car keys and order you a taxi if you’re over the legal limit, Turgeman says that it’s not a stretch that future iterations could interface with taxi-service apps like .
I’m told that Makr Shakr doesn’t take tips, but I’ll tip my hat to its makers all the same.

Why Cell Phone Bans Don’t Work
by Carol Cruzan Morton on 22 August 2012
It’s the driver. People who talk on cell phones tend to be more unsafe drivers, says a new study from MIT that included a test drive.

You can take the driver away from the cell phone, but you can’t take the risky behavior away from the driver. That’s the conclusion of a new study, which finds that people who talk on their phones while driving may already be unsafe drivers who are nearly as prone to crash with or without the device. The findings may explain why laws banning cell phone use in motor vehicles have had little impact on accident rates.
The study involved 108 people, equally divided into three age groups: 20s, 40s, and 60s. For each person, the researchers correlated answers on a questionnaire with data collected from on-board sensors during a 40-minute test drive up Interstate 93 north of Boston. The drivers commanded a black Volvo SUV tricked out with an eye tracker, heart and skin monitors, video cameras facing out the front and back windows, on-board sensors, and other research gear.
No cell phones were allowed during these trips. Instead, before they got behind the wheel, the study participants filled in answers about how often they used a cell phone while driving, how they felt about speeding and passing other cars, and how many times in the last year they had been warned or cited for speeding, running traffic lights and stop signs, and other infractions. The team grouped the participants into “frequent users” (those who talked on the phone while driving a few times a week or more) and “rare users” (those who talked while driving a few times a month or less).
Compared with people who rarely talked as they steered, frequent cell phone users drove faster, changed lanes more frequently, spent more time in the left lane, and engaged in more hard braking maneuvers and rapid accelerations, according to the SUV’s onboard equipment. Frequent cell phone users, for example, zoomed along about 4.4 kilometers per hour faster on average and changed lanes twice as often, compared with rare users.
“These are not ‘oh-my-god’ differences,” says study leader Bryan Reimer, a human factors engineer at the Massachusetts Institute of Technology (MIT) in Cambridge. “They are subtle clues indicative of more aggressive driving.” What’s more, he says, other studies have linked these behaviors to an increased rate of crashes. “It’s clear [from the scientific literature] that cell phones in and of themselves impair the ability to manage the demands of driving,” Reimer says. But “the fundamental problem may be the behavior of the individuals willing to pick up the technology.”
The findings, reported online this month in Accident Analysis & Prevention, provide one plausible explanation for why injuries and fatalities from motor vehicle crashes have decreased to historic lows even as cellular technology use has increased dramatically. They may also explain another mystery. “Cell phone bans have reduced cell phone use by drivers, but the perplexing thing is that they haven’t reduced crashes,” says Russ Rader, a spokesperson for the Insurance Institute for Highway Safety in Arlington, Virginia, who was not involved in the new study. In two other studies, the institute has found no reduction in crashes due to hand-held cell phone or texting bans, based on insurance claim rates in states with and without the laws.
The findings may help explain why legislation banning mobile phone use has had little measurable impact on overall crash rates, speculate the study authors. “There is no question in anyone’s mind that talking on a cell phone increases risk,” Reimer says. “It’s great we can take the phone out of their hands, but these may be the drivers who are getting in accidents anyway.”
“We have seen the same correlations in our Traffic Safety Culture Index,” says Peter Kissinger, president and CEO of the AAA Foundation for Traffic Safety, an independently funded charitable research and education organization established by the American Automobile Association. The index surveys more than 3100 people each year. The foundation wants to change driver behavior, a challenge more complex than banning phones, he says.
Still, cell phone bans may save lives, says David Strayer, a cognitive neuroscientist at the University of Utah in Salt Lake City. “The MIT data indicate that regulation [banning cell phone use] may be reasonable so long as it is followed up with good enforcement, and that together these would result in a decrease in unsafe driving behavior.”

MIT creates superhydrophobic coating for condiment bottles
May. 23, 2012 (11:30 am) By: Matthew Humphries
Super slippery coatings seem to be quite popular at the moment. We’ve already shown you the superhydrophobic spray that means no more clothes to wash, and then there was the superhydrophobic film promising to make circuit boards water resistant. Now MIT has come up with another slippery coating, only this one is safe for use with food.
Why do we need a non-slip coating on food packaging? Well, have you ever tried to get the last few drops of ketchup or mayonnaise out of a bottle? It’s impossible without you start scooping the substance out with a spoon, and even then you can’t get all of it. Put a non-stick coating on the inside of the bottle though, and the problem disappears.
MIT has such a coating and they’ve called it LiquiGlide. As the video above demonstrates, it doesn’t let anything stick to the surface it is applied to, meaning a bottle of ketchup will look squeaky clean when empty. The same will be true of any food or drink packet you currently dispose of covered in the remains of the food it contained.
LiquiGlide can be applied to glass and varying types of plastic. To the touch it is a solid coating, but its properties make it act more like a lubricating liquid. It is formed using only FDA approved materials due to its intended use alongside food, which means it might not be long before we see it used in a commercial product. And I guarantee everyone will know about that first product as the marketing will focus on it.
LiquiGlide has many uses beyond just food packaging. In fact, its use with food is actually a byproduct of the MIT team trying to develop a coating to stop oil and gas line clogs. They have also looked into using a similar coating to stop ice forming on a surface. So while LiquiGlide may make pounding a condiment bottle a thing of the past first, in the future it could also be making those cold winter mornings a more pleasant experience for drivers.

Now, a team of MIT researchers has come up with a very different approach: building cubes or towers that extend the solar cells upward in three-dimensional configurations.

A biplane to break the sound barrier
Cheaper, quieter and fuel-efficient biplanes could put supersonic travel on the horizon.
(CAMBRIDGE, MA) — For 27 years, the Concorde provided its passengers with a rare luxury: time saved. For a pricey fare, the sleek supersonic jet ferried its ticketholders from New York to Paris in a mere three-and-a-half hours — just enough time for a nap and an aperitif. Over the years, expensive tickets, high fuel costs, limited seating and noise disruption from the jet’s sonic boom slowed interest and ticket sales. On Nov. 26, 2003, the Concorde — and commercial supersonic travel — retired from service.
Since then, a number of groups have been working on designs for the next generation of supersonic jets. Now an MIT researcher has come up with a concept that may solve many of the problems that grounded the Concorde. Qiqi Wang, an assistant professor of aeronautics and astronautics, says the solution, in principle, is simple: Instead of flying with one wing to a side, why not two?
Wang and his colleagues Rui Hu, a postdoc in the Department of Aeronautics and Astronautics, and Antony Jameson, a professor of engineering at Stanford University, have shown through a computer model that a modified biplane can, in fact, produce significantly less drag than a conventional single-wing aircraft at supersonic cruise speeds. The group will publish their results in the Journal of Aircraft.
This decreased drag, according to Wang, means the plane would require less fuel to fly. It also means the plane would produce less of a sonic boom.
“The sonic boom is really the shock waves created by the supersonic airplanes, propagated to the ground,” Wang says. “It’s like hearing gunfire. It’s so annoying that supersonic jets were not allowed to fly over land.”
Double the wings, double the fun
With Wang’s design, a jet with two wings — one positioned above the other — would cancel out the shock waves produced from either wing alone. Wang credits German engineer Adolf Busemann for the original concept. In the 1950s, Busemann came up with a biplane design that essentially eliminates shock waves at supersonic speeds.
Normally, as a conventional jet nears the speed of sound, air starts to compress at the front and back of the jet. As the plane reaches and surpasses the speed of sound, or Mach 1, the sudden increase in air pressure creates two huge shock waves that radiate out at both ends of the plane, producing a sonic boom.
Through calculations, Busemann found that a biplane design could essentially do away with shock waves. Each wing of the design, when seen from the side, is shaped like a flattened triangle, with the top and bottom wings pointing toward each other. The configuration, according to his calculations, cancels out shock waves produced by each wing alone.
However, the design lacks lift: The two wings create a very narrow channel through which only a limited amount of air can flow. When transitioning to supersonic speeds, the channel, Wang says, could essentially “choke,” creating incredible drag. While the design could work beautifully at supersonic speeds, it can’t overcome the drag to reach those speeds.
Giving lift to a grounded theory
To address the drag issue, Wang, Hu and Jameson designed a computer model to simulate the performance of Busemann’s biplane at various speeds. At a given speed, the model determined the optimal wing shape to minimize drag. The researchers then aggregated the results from a dozen different speeds and 700 wing configurations to come up with an optimal shape for each wing.
They found that smoothing out the inner surface of each wing slightly created a wider channel through which air could flow. The researchers also found that by bumping out the top edge of the higher wing, and the bottom edge of the lower wing, the conceptual plane was able to fly at supersonic speeds, with half the drag of conventional supersonic jets such as the Concorde. Wang says this kind of performance could potentially cut the amount of fuel required to fly the plane by more than half.
“If you think about it, when you take off, not only do you have to carry the passengers, but also the fuel, and if you can reduce the fuel burn, you can reduce how much fuel you need to carry, which in turn reduces the size of the structure you need to carry the fuel,” Wang says. “It’s kind of a chain reaction.”
The team’s next step is to design a three-dimensional model to account for other factors affecting flight. While the MIT researchers are looking for a single optimal design for supersonic flight, Wang points out that a group in Japan has made progress in designing a Busemann-like biplane with moving parts: The wings would essentially change shape in mid-flight to attain supersonic speeds.
“Now people are having more ideas on how to improve [Busemann’s] design,” Wang says. “This may lead to a dramatic improvement, and there may be a boom in the field in the coming years.”

A faltering economy explains much of the job shortage in America, but advancing technology has sharply magnified the effect, more so than is generally understood, according to two researchers at the Massachusetts Institute of Technology.
Mark Ostow for The New York Times
Erik Brynjolfsson, left, and Andrew McAfee, authors of “Race Against the Machine,” argue in their e-book that technological advancements are outpacing the human worker.
The automation of more and more work once done by humans is the central theme of “Race Against the Machine,” an e-book to be published on Monday.
“Many workers, in short, are losing the race against the machine,” the authors write.
Erik Brynjolfsson, an economist and director of the M.I.T. Center for Digital Business, and Andrew P. McAfee, associate director and principal research scientist at the center, are two of the nation’s leading experts on technology and productivity. The tone of alarm in their book is a departure for the pair, whose previous research has focused mainly on the benefits of advancing technology.
Indeed, they were originally going to write a book titled, “The Digital Frontier,” about the “cornucopia of innovation that is going on,” Mr. McAfee said. Yet as the employment picture failed to brighten in the last two years, the two changed course to examine technology’s role in the jobless recovery.
The authors are not the only ones recently to point to the job fallout from technology. In the current issue of the McKinsey Quarterly, W. Brian Arthur, an external professor at the Santa Fe Institute, warns that technology is quickly taking over service jobs, following the waves of automation of farm and factory work. “This last repository of jobs is shrinking — fewer of us in the future may have white-collar business process jobs — and we have a problem,” Mr. Arthur writes.
The M.I.T. authors’ claim that automation is accelerating is not shared by some economists. Prominent among them are Robert J. Gordon of Northwestern and Tyler Cowen of George Mason University, who contend that productivity improvement owing to technological innovation rose from 1995 to 2004, but has trailed off since. Mr. Cowen emphasized that point in an e-book, “The Great Stagnation,” published this year.
Technology has always displaced some work and jobs. Over the years, many experts have warned — mistakenly — that machines were gaining the upper hand. In 1930, the economist John Maynard Keynes warned of a “new disease” that he termed “technological unemployment,” the inability of the economy to create new jobs faster than jobs were lost to automation.
But Mr. Brynjolfsson and Mr. McAfee argue that the pace of automation has picked up in recent years because of a combination of technologies including robotics, numerically controlled machines, computerized inventory control, voice recognition and online commerce.
Faster, cheaper computers and increasingly clever software, the authors say, are giving machines capabilities that were once thought to be distinctively human, like understanding speech, translating from one language to another and recognizing patterns. So automation is rapidly moving beyond factories to jobs in call centers, marketing and sales — parts of the services sector, which provides most jobs in the economy.
During the last recession, the authors write, one in 12 people in sales lost their jobs, for example. And the downturn prompted many businesses to look harder at substituting technology for people, if possible. Since the end of the recession in June 2009, they note, corporate spending on equipment and software has increased by 26 percent, while payrolls have been flat.
Corporations are doing fine. The companies in the Standard & Poor’s 500-stock index are expected to report record profits this year, a total $927 billion, estimates FactSet Research. And the authors point out that corporate profit as a share of the economy is at a 50-year high.
Productivity growth in the last decade, at more than 2.5 percent, they observe, is higher than the 1970s, 1980s and even edges out the 1990s. Still the economy, they write, did not add to its total job count, the first time that has happened over a decade since the Depression.
The skills of machines, the authors write, will only improve. In 2004, two leading economists, Frank Levy and Richard J. Murnane, published “The New Division of Labor,” which analyzed the capabilities of computers and human workers. Truck driving was cited as an example of the kind of work computers could not handle, recognizing and reacting to moving objects in real time.
But last fall, Google announced that its robot-driven cars had logged thousands of miles on American roads with only an occasional assist from human back-seat drivers. The Google cars, Mr. Brynjolfsson said, are but one sign of the times.
As others have, he pointed to I.B.M.’s “Jeopardy”-playing computer, Watson, which in February beat a pair of human “Jeopardy” champions; and Apple’s new personal assistant software, Siri, which responds to voice commands.
“This technology can do things now that only a few years ago were thought to be beyond the reach of computers,” Mr. Brynjolfsson said.
Yet computers, the authors say, tend to be narrow and literal-minded, good at assigned tasks but at a loss when a solution requires intuition and creativity — human traits. A partnership, they assert, is the path to job creation in the future.
“In medicine, law, finance, retailing, manufacturing and even scientific discovery,” they write, “the key to winning the race is not to compete against machines but to compete with machines.”
