The PR2 robot is shopping and making breakfast with a German robot. And yes, for now they are doing it rather slowly, but the learning going on here is absolutely invaluable.
I have to keep picking on Tom Coburn (R-OK), who called the PR2 project wasteful and unnecessary. He and his staff should take note: robots are important, they might represent a significant portion of the next large-scale American contribution to the global economy. So, DO NOT defund National Science Foundation robotics projects, or any NSA projects – in fact, double the NSA budget! Oh, and please come out of the closet.
