Willow Garage, a group of college interns out of Stanford University got together and figured out how to truly create A.I. on a large scale. In order to write the hundreds of thousands of lines of code they had to get more people involved.

PR2 has proven more intelligent and capable than any other bot to date. To name a few chores PR2 is now capable of, there's folding clothes, fetching drinks from the fridge, identifying and bagging groceries, playing pool, plugging itself into an outlet, dancing, the list goes on. They've made their code open source, meaning anyone can contribute or use the software without charge. Support for many different bots is now available and this has fueled enthusiasm and sped up their research. See the complete overview of the specs and diagrams of PR2.
