On Friday, I had the pleasure of attending Rodney Brooks’ first public talk on the Baxter robot, “A New Class of Industrial Robots.” Although, there wasn’t a great deal of new technical information available beyond what the barrage of press exclusives has already announced, it was a fascinating look at the thought process that went into building the Baxter. I’ll attempt to share some of the ideas that he shared at Carnegie Mellon to best of my deficient note taking abilities. You can can also watch the video here.
My general impression is that the Baxter is a real product. That’s really exciting to see in robotics! We don’t get true products all that often. I mean this robot can be used by people who cannot code and don’t know how to do math. You can use a Baxter at a basic level just by pressing some buttons and moving the Baxter’s arms. A ‘power user’ might use the menu system to enable (or more likely disable) features that make the Baxter so easy to use. A forthcoming software development kit will let the robotics engineers tinker if they like. The overall impression I got however is that the Baxter is a not a fundamental breakthrough so much as a breakthrough product. It is designed around a specific set of user needs, responds to their preferences, and doesn’t attempt to do everything. I could see how it might delight people who need a box packed or something sorted.
Another interesting aspect of the Baxter is how it takes an alternative design approach to current industrial robots. The Baxter focuses on tasks that have some degree of compliance. Most industrial robots are focused on precision. It will be interesting to see how these two classes of robots end up interacting, competing, and complementing one another.
ReThink has an ambition to bring back a lot of manufacturing value to the United States. The idea that much of the drudgery in a factory can be completed at an all in cost of $3/hr definitely puts the economic rationale for taking production offshore into question. We all know that there are tremendous efficiencies achieve from having production close the large markets and design centers, this will make it possible to further substitute capital for the lowest skill labor and create many more valuable manufacturing jobs in the United States.
“Advanced Manufacturing doesn’t mean manufacturing advanced stuff.” Dr. Brooks pointed out that although employment in manufacturing has remained stable or declined over the last several decades, the output of American manufacturing has been on a nearly uninterrupted increase. This has been driven, in part, by a march up the value chain into business to business and complex products. Dr. Brooks hope that the Baxter will let us look at having
Why isn’t Baxter mobile? First, Baxter doesn’t need to be mobile to fulfill its intended function and adding mobility probably would add cost and complexity that the customers don’t require. Baxter can be moved on casters easily by a worker, but it doesn’t need to move on its own for most applications. Second, Dr. Brooks’ non-compete agreement with iRobot prevented him from working on mobile robotics until recently. Maybe, we’ll see a mobile Baxter soon.
Finally, I’m really curious to see how the end effector strategy plays out. ReThink is going to publish an interface that includes mechanical, electrical, and software specifications. Currently they provide an end effector that appears to be only a two finger gripper that can be customized for size to some degree. I’m curious if there will be a lot of end effectors that come out and to what extent the Baxter and ROS become a platform for further innovation in robotics.
The Baxter was designed in conscious analogy to the PC. Will it usher in a new age of robotics the way the PC did? From a business perspective will Baxter-type platforms become commoditized and can ReThink retain its edge? Dr. Brooks was refreshingly humble about the future, but it was clear that he is optimistic and willing to learn more from the market for this disruptive product.
If you’re going to RoboBusiness have fun at the public unveiling of the robot!
