Our conversation, though limited to half-an-hour, spanned many topics but mostly centered around the role robotics can play in bringing back manufacturing to America. Brooks was on the faculty of MIT as the Panasonic Professor of Robotics and is also the man who started iRobot, the company well known for its household chores robot, Roomba. It was during the process of building iRobot when he realized that robots were going to be key for rethinking and re-imagining low-cost manufacturing in the twenty-first century.
During his Roomba-phase, it became quite clear to Brooks that low-cost manufacturing economies often run into the ceiling of rising standards of living. From Japan to South Korea, from Taiwan to China and more recently to Vietnam — the low cost manufacturing hot-spots continue to shift and there is nothing wrong with the shift, Brooks argues.
However, what happens when the world runs out of shifting manufacturing bases such as those in Asia? Another thing on the mind of Brooks: oil price spikes were adding a fuel surcharge on the low cost products. And there is always the looming threat of intellectual property being compromised. Brooks points out that there are a lot of Roomba replicas. “The big question to me was, ‘can we make low cost goods in the US?’” he said. “It is clear we can’t pay the same wages as places like China.”
It was this backdrop which lead him to start Rethink Robots in 2008 to work on manufacturing robots. It was originally called Heartland Robotics and has raised $57 million in funding from the likes of Jeff Bezos’ Bezos Expeditions, Highland Capital Partners, Charles River Ventures, Sigma Partners and Draper Fisher Jurvetson.
Cheap but not cheesy
Today when we think of manufacturing robots, we quickly recall giant robots that are installed in the car plants inside body shops and paint shops. They cost millions of dollars and are programmed by specialists to do very specific tasks. They are like the mainframes of manufacturing robots.
And that is why the development and release of Baxter is so interesting. It is an inexpensive (sub-$25,000) semi-anthropomorphic line robot that is relatively simple to program. It is very flexible. And it has the potential of reshaping the manufacturing processes — first in mind-numbingly boring tasks such as packaging and removing things off a conveyer belt. “It doesn’t have the dexterity to build an iPhone, but it sure can package an iPhone,” Brooks quipped.
As technology has become more pervasive in our lives, most of us (and by that I don’t mean the early adopters) have gotten used to working with technology without needing manuals. The popularity of touch-based smartphone and society’s growing ease of using search and Facebook means that today, if you make robots simple enough, it is less likely that folks are going to be overwhelmed by them. The trick is to make them augment the humans in the manufacturing process.
What about society’s natural fear of robots and them taking over the world? Brooks laughed, and then pointed out that just as electric drills have made the jobs of construction workers easier, the same goes for these manufacturing robots. Just as computers opened up new opportunities, Baxter and its descendants are going to create new opportunities. Brooks knows it is going to take a long time.
“Simple tasks today,” Brooks said. More complex task will follow in time, thanks to the marriage of hardware and software, he added. In thirty years we have gone from mainframes to computers in our pocket and soon they will be embedded into our bodies, Brooks says. Robots are going to go through the same curve as well.
Smartphones say hello to robots
Like Brooks, I am a firm believer in a future where such machines start to assist in our daily tasks, though the final shape and form of these machines might look entirely different. Will robotics progress fast enough to bring manufacturing back to U.S.? Who knows. After all, we are still not clear as to what kind of manufacturing base we want to build. But the future is exciting and full of possibilities nonetheless.
What is even more exciting — well, at least to me — is that the road to this robotic future is littered with billions of smartphones. The reason why we can build robots like Baxter today is because of the falling prices of sensors and other components. Before the iPhone rolled around, phones didn’t use that many chips. Apple came along and made it normal to demand pyrometers, accelerometers, digital cameras, touch and other such sensors.
