This Sunday, January 28 starting at 8:00pm the National Geographic Channel is going inside three high-tech U.S, factories for Ultimate Factories. The first stop is the Harley-Davidson factory at 8:00pm, followed by the Peterbuilt factory at 9:00pm and the Anheuser-Busch Brewery at 10:00pm. If you enjoy getting drunk, riding motorcycles, trekin' across the country on a big rig, or doing all those things at once, then you might want to check out these programs to see how it all comes together. You'll find out how humans and robotics work together at Harley-Davidson to make sure the motorcycles run perfectly, and how every Peterbuilt semi is constructed so that no two are exactly alike.
