"The thing about the future is this: we'll still have to do menial things like answer the door, or take out the trash, or get up off our couches to get our own brews after a long, hard day at the office... unless we're smart enough to invent robots to do such menial things, that is. Well, Willow Garage has spent some time building a \"Beer Me\" application for its PR2 robot which gets at least one of these tasks under its belt. They added a four-holed foam block placed behind the robot's navigation laser so that it can safely carry four bottles across the terrain, and equipped their refrigerator with a tilted \"self-stocking\" shelf. Check out its operation in the video below."^^<http://www.w3.org/2001/XMLSchema#string>
