A Sputnik II Moment

I was disappointed with the section of President Obama's 2011 State of the Union speech regarding investing in selected new technologies for future growth.

I had hoped he would use the word “robotics” and include the necessity for an American robotics industry in his speech and it is unfortunate that he did neither. That he focused his investment scope to exclude robotics might just be the death knell for the American robotics industry because, without national strategic focus, things will go on as they have… VERY slowly and very dependent on Space and Defense for research dollars.

A thriving robotics industry provides jobs, helps the nation increase efficiency, profitability and productivity and upgrades the mix of workers involved. Yet America doesn't presently have a national robotics agenda. Europe does. Japan does. Korea does. And each of these countries is gaining success and momentum worldwide.

Tom Atwood, editor-in-chief of Robot magazine, recently stated:
Although the government is beginning to wake up and push for an expansion of robotics education in schools with the DARPA-funded FIRE (Furthering Innovation through Robotics Exploration) program at Carnegie Mellon and the NSF-funded DARwIn-OP project at Virginia Tech, these and similar programs, by themselves, are not enough for our country to maintain its competitive technological edge. We need a national robotics policy that is specifically articulated in a clear call to action by our executive branch, and we need backing of such a program by Congress.
Pres. Obama was inspiring in his speech and his directness to the issues of the day, and his reference to a Sputnik II moment was wonderful as he attempted to address the need for American students to become involved in STEM (science, technology, engineering and math) programs. This is a serious issue and a major difference between America and all of the other countries in which robotics flourish: STEM education takes extra dedication, energy, time and persistence which is not happening with American students; in fact there seems to be resistance to pursuing a career in science (except for a career in medicine, or on the business side of math - as a quant - which, even today, still equates to enormously big bucks.) The Sputnik reference was eloquent but, at least for robotics, empty.

Microsoft Kinect - add-on device for Xbox game controller
He missed some great technology examples.  One that I find particularly illuminating is the effect that the technology inside Microsoft’s new Xbox Kinect device has had. Kinect is a controller free gaming and entertainment experience. It enables users to control and interact with the Xbox 360 game system without the need to touch a controller, through a natural user interface using gestures and spoken commands. Not only have sales of Xboxes exploded but so have the applications and uses - and sales - of the cameras and depth-perception software inside the Kinect. iRobot and WillowGarage are using the $50 Kinect innards in lieu of LIDAR range-finder machines costing upwards of $5,000. Check out iRobot’s new AVA concept robot. Hackers and inventors worldwide have been finding new uses for the Kinect that Microsoft didn't even dream of. Now that’s inspiring!

There are many things happening in robotics in America. There's work underway - with some successes thus far - to get an American robotics roadmap funded and implemented and there's been a steady trickle-down effect from the research dollars spent on defense and space by NASA, DARPA and the DoD. Medical robotics are on a tear. There is independent investment as well. In Wisconsin, Indiana, Georgia, Massachusetts and Alabama, state-, corporate- and educationally-sponsored Robotic Centers are springing up to provide training in the programming, repair and maintenance of robots, as well as for research and testing. Alabama's recently opened Robotics Technology Park is a serious $73 million three-pronged endeavor to provide (1) an industry training program where technicians will be trained to work on robotic machinery; (2) a test facility for NASA and the US Army for research and testing of leading edge robotics for defense and space exploration; and (3) a facility to allow start-up companies to build and adapt robots for new industries. Imagine if this kind of state-inspired public-private forethought were done on a national level... now that's a Sputnik II moment.

Alison Diana at InformationWeek just did a piece on 12 Advances in Medical Robotics but failed to note that 2/3 of the vendors were not American.  Eight out of the 12 were Japanese, Korean or European. The ratio of industrial robot providers in America is even worse: although integrators, engineers and consultants tend to be American-owned, the major robot providers (KUKA, ABB, Comau, Denso, Schunk, Motoman, Daihen, Reis, Fanuc) are all foreign-owned. That is also a Sputnik II moment.

English Teaching Robot
In South Korea, robotic guides and docents patrol the Presidential Museum as 70,000 monthly visitors experience an advertisement of the nation’s cutting-edge technologies that made it a global leader in chips, mobile phones, TVs, display panels, and robotics that combine them all. South Korea is into the 5th year of a 10-year $1 billion investment in robotic technologies with a series of national goals endorsed by their President.

An example of how a nationally-directed strategic program works is when a shortage of English teachers compelled the South Korea government to use robotic teachers. They are deploying them in 500 preschools in 2011, and 8,000 preschools and kindergartens by 2013. It helps address the lack of English teachers in rural areas or remote islands. Learning English represents a necessary educational step for competitive South Korean students, and especially those aiming to study abroad at major universities in the U.S. Now that's a Sputnik II moment.

This is what was missing from President Obama's speech: the recognition that part of the underbelly of America's productivity and efficiency is automation and robotics. It's a very necessary industry which needs national direction. Mark Ingebretsen, the new editor of Robotic Trends Business Review,  adds an additional dimension to Pres. Obama’s exclusion of robotics, “the robotics that drive America’s economy and defense will be in the hands of other countries that have spent the early 21st century developing robot technologies.”

President Obama's call for action using the Sputnik II example is moot in relation to robotics without the formulation and acceptance of a roadmap and the establishment of a public-private consortium to implement it fully. A roadmap was presented in May, 2009 and some of it's provisions are slowly making their way through the halls of Congress. But there is no executive leadership thus far. If there were, Pres. Obama's Sputnik II moment would be a true call to action instead of pointless rhetoric.

Big Changes in Robotic Manufacturing

2011 is a pivotal year for industrial and service robots. In fact, we may see the marriage of industrial with service robots to be used as assistants in manufacturing. The recent launches in Europe of pi4-robotics' workerbot and Japan's Motoman's two-armed headless robot, and the anticipated 2011 launch in the U.S. of Heartland Robotics' factory assistant robot are examples of this trend.

Henrik Christensen (Director Robotics and Intelligent Machines, Georgia Institute of Technology) said in a recent ROBOTICA Forum:
In manufacturing only through use of automation can we reduce the need to out-source. Our workers are not going to be more effective in doing manual labor, but with the right tools they can be more effective and the motivation to outsource less pronounced. Companies are starting to realize that once you start an out-sourcing process it may result in all of the process going off-shore. That happened in textiles and apparel and the poster child in the IT industry is the IBM ThinkPad transformation to Lenovo laptops. Also the disk drive industry had a similar move to Singapore.

To be effective, robots have to be lower cost and higher dexterity. We are starting to see this - and the cost of integration is also coming down.
The recently released 2010 robotics industry reports from the International Federation of Robotics said:
Dramatic advances in robotics and automation technologies are even more critical with the next generation of high-value products that rely on embedded computers, advanced sensors and microelectronics requiring micro- and nano-scale assembly, for which labor-intensive manufacturing with [low-skilled] human workers is no longer a viable option.
Here are some quotes from the Heartland Robotics website that are more real than hyperbole:
Today's manufacturing robots are big and stiff, unsafe for people to be around, engineered to be precise and repeatable, not adaptable. Normal workers can't touch them.

Our robots will be intuitive to use, intelligent and highly flexible.  They'll be easy to buy, train, and deploy and will be unbelievably inexpensive.
Similar wording can be found on the pi4-robotics website and Motoman's.

Today's industrial robots are truly expert systems

Lest we forget, industrial robots encapsulate years of translating the skills of craftsmen to the mechanical capabilities of robots.  There's no other way that robots could have replaced their human counterparts were it not for the fact that the robot can do the same task equal to or better than the human.

Industrial robots in car factory
The know-how, where robots mimic human actions in the various aspects of the auto industry, represents decades of accumulated knowledge transfer by veteran craftsmen.

In welding, for example, the finish of welding varies, depending on the kind of metal used, its thickness and the power voltage. Craftsmen adjust the speed of welding by observing how sparks fly to get the best finish. From a story in Asahi:
About 10 years ago, Yasakawa (Motoman) started filming its craftsmen at work, using a high-speed camera to record their hand movements. The accumulated data was programmed into robots to enable them to perform tasks from several thousand options of welding that craftsmen had established over the years.

Because Yaskawa makes and uses robots at its main factory, it enables the company to pass along technical expertise from elders to their juniors.

"You can copy a robot, but not control technology that craftsmen created," said Junji Tsuda, president of Yaskawa. "(Exporting robots) is like shipping the craftsmen themselves."

"Chinese and South Korean makers are less likely to come up with such technology because they are more inclined to want results in the short term," said Akira Yoshino, the engineer-inventor of the lithium-ion battery.
Presently, robots in manufacturing are, except for the auto industry and welding apps, mostly involved in post processing and packaging rather than in the manufacturing process. [This latter point is not to be minimized - in fact, it is a booming area of robotics: picking, packing, packaging, processing, sorting and warehousing.]

But not general manufacturing!

The near-term future will see the gradual appearance of multi-purpose, flexible, easily trainable robots. We are likely to see the bridging between the expert systems of the past and these flexible systems of the future - in manufacturing in 2011.

I see three issues involved:
  1. Robotics for Small and Medium-sized manufacturers and factories (SME's)
  2. National strategies to solve important issues
  3. Training and retraining people for the future
SME's are the life-blood of the middle class and the area of greatest jobs growth.  SME's create new jobs, contribute to the community, and produce needed products.

Yaskawa Motoman
Two-armed Factory Robot
A few years ago, in Europe, the EU recognized the need to support SME businesses with improved robotics - robotics that were easily trainable, safe to work alongside, relatively inexpensive and flexible enough to handle all sorts of ad hoc tasks in any quantity. The EU invested in the development of SME robots because they felt that without their investment production efficiencies couldn't be maintained and more and more manufacturing would move offshore. The SME project ended early in 2009 and the consortium members quickly brought products to market that address the needs of SME's. These include two-armed robots, safety sensors and train-by-example programming. The EU also invested in the PiSa Project which had a similar goal.  The pi4-robotics "workerbot" mentioned above is the result of that effort. Motoman's two-armed robot is an outgrowth of the SME project and is presently replacing older robots in the Mercedes factories.

America doesn't have a national robotics agenda (roadmap) just yet even though there is effort in that direction. Congress was presented with a roadmap in May, 2009. There has been some movement from the Obama Administration's Office of Science and Technology Policy including some SBA funding and some targeted areas of robotic development funding opportunities from five different government agencies. But robotics are not yet on the national agenda - there's no U.S. Robotics Initiative as there is for other areas of development.

Nor is there a real training and retraining mechanism for keeping up with the changing technological landscape. Instead, we fear losing jobs rather than understanding that we will instead change the mix of workers (as is generally the case when robots enter the picture).  Yes we have FIRST programs, and interesting robo-competitions all oriented to interest students in STEM education. But we are very lax in our science education overall and really don't have a national reeducation program for our workforce.

What America has is an entrepreneurial system of funding (which I described back in January ("Financing the Strawberry Project")) supplemented by irregular special purposes like national defense (DARPA), homeland security and space exploration. If an inventor/business has a good enough idea to get past the angel investors and on to the real VCs, he/she will get enough money to get it off the ground.  It's part salesmanship, part product, and timing, rather than an outgrowth of a national agenda to help society.

It's great to wish Heartland Robotics well but it isn't right that they are America's only knight in shining armor (if it turns out that they really are). Also, if they are successful they will be contributing to the jobs issue by changing the mix of workers from low-skilled to highly skilled. Without a retraining program in place, there will likely be serious repercussions, a lot of bad press, and slowdowns.

Bill Gates, Samsung, the government of South Korea, Toyota, Ray Kurzweil and many others are predicting that there will be a robot in our homes, companies and cars in this decade.  It truly is a political issue - one of technological complexity, national importance and economic strategy - to make sure that we don't derail ourselves with pettiness, greed, apathy and inaction.
