This Idea Has Real Legs

Check out this video of Rex, The Robotic Exoskeleton.

An incredible advance for the disabled in providing better mobility.

Light years ahead of a wheelchair, Rex enables people to stand, walk, climb stairs, and generally lead more normal and healthy lives.

Rex is not meant to supplant the wheelchair (where you can sit), but to augment meant it (with the ability to stand).

"If you are a wheelchair user, can self transfer and use a joystick with your hand, Rex amy offer you a way to stand, move sideways, turn around, go up steps as well as walk on flat hard surfaces including ramps and slopes." (www.rexbionics.com)

The idea for REX came from the movie Aliens, where Ripley (Sigourney Weaver, the main character) fights the big mother Alien in a "Power Loader" suit. The exoskeleton designed for transporting and stacking large supply crates is used to do some serious damage to the Alien.

Exoskeletons have been explored as battle suits in movies, video games (Halo), and even in the real military as future combat wear.

Nice to see an application of the technology that can kill/maim to also heal/help people. Of course this isn't the first time military technology has been applied to the consumer market; for example, the Internet itself on which I am writing this blog, was developed by DARPA.

The point is that technology itself is not good or bad, but rather how we use it, is what determines it's ultimate effect.

According to CNN, Rex invested $10 million and seven years in developing this bionic dream machine made from 4700 parts. FDA approval is being sought, so Rex can be marketed it in the U.S.

It's not hard to imagine exoskeleton technology being used not only for helping the disabled and fighting future wars, but also for augmenting the everyday workforce as body bionics to work the fields, build our infrastructure, transport goods, and even for us intellectual types, to run between (or out of those) meetings that much faster.

Happy Birthday Internet

On September 2, 2009, the Internet celebrated its fortieth birthday.

ComputerWorld (14 Sept. 2009) reports that 40 years ago “computer scientists created the first network connection, a link between two computers at the University of California, Los Angeles.” This was the culmination of research funded by the Defense Advanced Research Projects Agency (DARPA) in the 1960s.

This information technology milestone was followed by another, less than two months later, on October 29 1969, when Leonard Kleinrock "sent a message from UCLA to a node at the Sanford Research Institute in Palo Alto, California."

While the Internet conceptually become a reality four decades ago, it didn’t really go mainstream until almost the 1990’s—with the founding of the World Wide Web project in 1989, AOL for DOS in 1991, and the Mosaic browser in 1993.

Now, I can barely remember what life was like before the Internet. Like the black and white pictures of yester-year: life was simple and composed, but also sort of lifeless, more boring indeed, and less colorful for sure. In other words, I wouldn’t want to go back.

Also, before the Internet, the world was a lot smaller. Even with connections to others far away—by phone and by plane—people’s day-to-day connections were more limited to those in close proximity—on their block, down on Main Street, or in and around town. It took an extra effort to communicate, share, deal, and interchange with people beyond the immediate area.

At present with the Internet, every email, chat, information share, e-commerce transaction, social media exchange, and application are a blast across the reaches of cyberspace. And like the vastness of the outer space beyond planet Earth, cyber space represents seemingly endless connectivity to others over the Internet.

What will the Next Generation Internet (NGI) bring us?

ComputerWorld suggests the following—many of which are already with us today:

  • Improved mobility—like “showing you things about where you are” (for example, where’s the nearest restaurant, restroom, or service station or even where are your friends and family members).
  • Greater information access—“point your mobile phone at a billboard, and you’ll see more information” about a particular advertisement.
  • Better e-commerce—“use the Internet to immediately pay for goods.”
  • Enhanced visualization—Internet will “take on a much more three-dimensional look.”

I believe the future Internet is going to be like Second Life on steroids with a virtual environment that is completely immersive—interactive with all five senses and like speaking with Hal the computer, answering your every question and responding to your every need.

It’s going to be great and I’m looking forward to saying “Happy Birthday Internet” for many more decades, assuming we don’t all blow ourselves out of the sky first.

Faith or Fear?

I love stories of hope and possibility.

I read in the Washington Post, 1 August 2009, about cars that actually enable blind people to drive. This was one of those stories.

In 2004, a challenge was issued from a blindness advocacy group “to build a vehicle that the blind could drive with the same freedom as the sighted.”

Around the same time, The Defense Advanced Research Projects Agency (DARPA)—the same government agency that brought us the Internet—“ran a series of contests to inspire a driverless car that could navigate complex terrain.”

However, at Virginia Tech’s Robot’s & Mechanism Laboratory the challenge of “an autonomous vehicle wasn’t enough. We want the blind person to be the driver, not to be driven.”

To meet this once unthinkable goal, the design team developed a prototype vehicle that blind students this summer are actually testing.

Here’s how the vehicle works: An all-terrain vehicle with a front-mounted laser sensor sweeps the terrain ahead, and a computer in the back processes the information into a two-dimensional map. A computer voice tells the driver through headphones what number of clicks to turn the wheel to steer around obstacles and a vest vibrates to indicate whether the driver should slow down or stop.

By challenging ourselves, bringing innovation to the table, thinking positively, and working through the challenges, we are able to bring opportunities to people that many thought were impossible.

Yet even today, I heard people reacting to this story and saying “Oh, I wouldn’t want a blind person driving behind me.”

But why not? There are reasons to believe that this can work.

First of all, in the vehicle tests, the blind drivers actually did better than the engineers because they followed the directions coming from the computer more precisely.

Second, when it comes to other modes of transportation such as flying, people no longer seriously question the use of technology to aid our ability to see, navigate and fly through all sorts of weather and turbulent conditions. Now a days, a large commercial airplane flying at hundreds of miles an hour over densely populated cities on autopilot is an accepted fact.

I believe there are really two issues here:

On one hand, is the technology itself. How far can technology take us—are there limits?

And the second issue is can people overcome their mindset of fear, doubt, hesitation, and negativity to really stretch the bounds of the imagination to the what’s truly possible?

I think both the issues of technology and mindset are strongly related.

Obviously there are laws of nature and physics that place real limits on even how far technology can take us. Yet, as we press against the boundaries and test the seemingly impossible, we are able do things that practically defy those very laws. For example, who would’ve thought that man could fly like the birds, walk on the moon, communicate thousands of miles in a split second, or cure the incurable? Perhaps, what we perceive as physical limitations are only there until we can figure out how to overcome them with innovation and technology—and of course, the wisdom bestowed from the almighty.

By realizing that the boundaries are not so hard and fast—that they are elastic—we can have hope in going further and doing the seemingly impossible.

Certainly, I recognize the very real legitimacy of the concerns that people might have over the thought of blind people in the driver’s seat. However we must ask ourselves how much of this concern is based on rational, logical factors and how much on a misperception or mistrust of what technology—and blind people themselves—can actually do. To me, it really comes down to one’s mindset.

Through faith, courage, conviction, we can overcome our doubts and fears. We can and must continue to explore, to test the bounds, and to innovate some more.

DARPA and Enterprise Architecture

As a discipline enterprise architecture strives to move the organization into the future—that is what EA planning and IT governance is all about—and that is also what an organization like DARPA is about.

“The Defense Advanced Research Projects Agency (DARPA) is an agency of the United States Department of Defense responsible for the development of new technology for use by the military. DARPA has been responsible for funding the development of many technologies which have had a major impact on the world, including computer networking [the Internet]DARPA’s original mission, established in 1958, was to prevent technological surprise like the launch of Sputnik, which signaled that the Soviets had beaten the U.S. into space. The mission statement has evolved over time. Today, DARPA’s mission is still to prevent technological surprise to the US, but also to create technological surprise for our enemies. DARPA is independent from other more conventional military R&D and reports directly to senior Department of Defense management. DARPA has around 240 personnel (about 140 technical) directly managing a $3.2 billion budget.” (Wikipedia)

National Defense Magazine, November 2007, states that DARPA “has a reputation for taking on challenges that sometimes seem to defy the laws of physics—or at least common sense.”

“’DARPA Hard’ refer to problems its researchers attempt to solve...’Please tell us that it’s something that can’t be done. It’s science fiction. That is a challenge we can’t resist,’” says Brett Giroir, director of the defense sciences office.

Here are some interesting target architectures that DARPA has set out to tackle:

  • Transparent walls—“DARPA wants to defeat rock, concrete and plaster walls—not by blowing them up—but rather by making them transparent. The agency is creating a suite of sensors to map the inside of buildings, tunnels, caves, and underground facilities.” The Visi-building project ,for example, uses radar to detect the inside of buildings, and then DARPA is exploring how to penetrate and destroy without resorting to nukes.
  • Inner Armor—“the objective is to fortify the entire soldier against attack from the enemy of the environment.” This includes environmental hardening to “protect soldiers from extreme heat, cold, and high altitudes,” and kill proofing “to protect soldiers from chemical and radiological threats,” as well as safeguarding them from deadly diseases. It’s a comprehensive protection package. DARPA for example envision “universal immune cells that are capable of making anti-bodies that neutralize…hundreds of threat agents.”
  • Chemical mapping—“there are about 80,000 commercially available chemicals, and many of them are toxic, DARPA wants to create a map showing where and if they appear in a given area.” This would show forces where chemical labs or weapons caches are. One idea is to use “replace sensors with nano-technology-based samplers that extract chemicals…[and that have ] a GPS device attached [that] could be placed on helicopters, military vehicles, or secretly placed on delivery trucks making rounds through a city”

These are great! You have got to love the “know no bounds” attitude of DARPA. They are truly innovators, and are a model for the rest of government and industry in defining problems and actually solving them.

In enterprise architecture, it is one thing to set targets that are incremental, non-monumental, and the same as everyone else is doing (like moving to Microsoft Vista). But it is an altogether different thing to set targets that are groundbreaking in terms of business process engineering and technology innovation.

While not all our targets can be revolutionary, perhaps a subset of them should be to keep us really innovating and not just copycatting the competition. We need to bring innovation back to the forefront of what we believe, how we think, what we do, and how we compete.

Military Robots and Enterprise Architecture

One reason that I love the military is that they truly think out of the box and are not only cutting-edge, but they continuously innovate. They drive change that ripples throughout all areas of the economy, and they use the best from the private sector and make it even cooler.

If you’re into robotics, you’ve most certainly heard of the Roomba from iRobot that vacuums floors on auto-pilot.

Now the military is taking that idea and through the Defense Advanced Research Projects Agency (DARPA) developing a robot that will aid battlefield communications.

MIT Technology Review, 11 March 2008, reports that “iRobot is developing communications robots for the military.”

“Expendable robots that can be tossed into a building or over a wall…will be used to set up communications networks to assist soldiers in urban battlefields,” where communication are often by impeded by obstacles and structures that “reflect, refract, diffract, and absorb radio signals leading to signal loss and attenuation.”

These robot are call Local Area Network or LAN-droids, and they will have autonomous positioning systems so that the bots will be mobile and be able to adapt to get the best signal. The bots “will use 801.11g Wi-Fi standards to form mobile ad hoc networks that can repair and reroute themselves if, for example, the enemy destroys a robot.”

The robots, each costing less than $100, will “weigh less than a kilogram and [be]…about 10 centimeters long,” so soldiers can carry multiple bots and be able to throw them into position.

The robots are planned to be able to travel at “half a meter a second and be capable of functioning for up to 10 hours.”

The LANdroids prototype is expected by the end of the year.

What a terrific target architecture! Focused on mission requirements with a vision for improved results of operation, DARPA is aligning technology solutions to the soldier’s needs for better, more reliable communication in the battlefield.

Further, the LANdroid is a solution that is grounded in market reality. Using the Roomba vacuum robot as a model for mobile bot technology, DARPA is taking it to the next level. They are applying the technology to their mission space and upping the ante on the adversary.

In a sense that is what EA is all about, staying one or more steps ahead of the competition whether in terms of business process efficiency, quality products and services, and technology enablement. EA engineers the organization to succeed.

Today it’s the LANDdroid, tomorrow the Battlefield KillerBot.
