Ronald Shrewsbery II used to be the Robot Doctor. Now he's known by the more bureaucratic-sounding title "WCM (World Class Manufacturing) Electrical Technical Specialist," but he still doctors the robots. There are a thousand of these machines inside Ohio's Toledo Assembly Complex, a 312-acre manufacturing leviathan dedicated to producing Jeeps. The Toledo Assembly Complex is one of the most heavily automated car factories in the United States. It can extrude 500 cars in a shift, far more than the Cove, the old Jeep plant that was shut down in 2006. And the machines make the work easier. There used to be a lot more lifting, more pushing.
