DARPA’s Gill Pratt: Cloud Robotics Next Big Thing
Dr. Gill Pratt, the man behind the DARPA Robotics Challenge, discusses what's next for robotics and how robots will soon learn from each other.
Pratt: There may be others. We had a number of workshops on multiple robots, but it’s not clear that that’s what’s going to go forward next. I don’t know. We change program managers in my job. You only stay there between two and five years, and so every year or two there’s something new that comes up.
Guardian: Google, Daimler and Uber all have self-driving cars now; how do you anticipate humanoid robots reaching the private sector?
Pratt: I think the next big thing to conquer is cost. All the prototypes that you saw were in the hundreds of thousands to millions of dollars. And once a market is identified, whether it’s in manufacturing or agriculture or ageing society, once someone kind of finds the match between the technology and the market, the costs will go way down, and that will be an amazing thing. The next neat thing that’s going to happen is cloud robotics: that’s where when one robot learns something they all learn something.
Let’s say you have a group of robots used for ageing society and their job is to clean up within your house. As each machine does its work, eventually one of them will come across an object and not know what it is, and it’ll reach out to the cloud, through the internet, and say: “Does anyone know what this thing is?” Let’s say that no one does. Then it’ll reach out to a person and the person will say: “Oh, that’s a jar of oil, and that belongs in the cupboard next to the jar of vinegar.” And the robot will say: “Got it!” And now every single one of them knows. In this way, you can bootstrap up the confidence of all the machines throughout the world. I think that will be the next technology.
Guardian: That sounds like robots using the cloud the way reporters use Twitter.
Pratt: Right, and that’s an amazing thing! And it’s enabled by the internet, right, so a sort of old Darpa thing feeding into a new Darpa thing and working together. Some of the computation can be done on the cloud, too, so you can offload that so the robot itself doesn’t have to burn up the power onboard to do lots of that work.
Guardian: Are you going to miss this?
Pratt: I am going to miss it tremendously. [DRC] was an amazing event. An extraordinary dream come true, actually.
