Hyundai uses more than 400 robots throughout the plant to assemble the Sonata and Elantra sedans. These robots weld and paint and precisely place windshields. Although two different cars are built at the plant, they're both built on one assembly line for efficiency's sake, something that's made possible by robots and human team members working in harmony. The Santa Fe crossover was added to the line on June 22.

Not all of Hyundai's robots require arms to so their job. The OneKit system employs a number of autonomous drones to transport parts across the assembly line. The wheeled automatons drive along a set path and can stop when a person or object is detected in front of it. After the object moves, the robot continues on its way. The Alabama plant is one of only two in the world to use these robots.
