Unimate

There is a Robot Hall of Fame, One of the inductees is the first automobile assembly line robot: Unimate:

In 1961 the first industrial robot, Unimate, joined the assembly line at a General Motors plant to work with heated die-casting machines. Unimate took die castings from machines and performed welding on auto bodies; tasks that are unpleasant for people. Obeying step-by-step commands stored on a magnetic drum, the 4,000-pound arm is versatile enough to perform a variety of tasks.
