Toyota Motor Manufacturing, Indiana (TMMI) uses high-tech manufacturing systems to assemble some of the most technologically advanced vehicles on the road today. TMMI has assembled more than 6 million vehicles — and counting. Since the plant’s groundbreaking in 1996, Toyota has invested $6.6 billion to make high-quality vehicles through smarter, flexible manufacturing and innovation. For instance, at TMMI employees work in tandem with robots to help increase efficiency. It’s not uncommon to see an employee donning an exoskeleton — like a harness — to get a boost and some support when working on a task that’s elevated. Employees also program the robots to perform various operations, including welding car body panels and painting bumper covers.
