Unimate at General Motors (1961)
General Motors installed the first industrial robot, Unimate, in a Trenton, New Jersey die-casting plant. The 4,000-pound arm lifted hot metal parts from die-casting machines, a job that injured human workers.
GM expanded use of Unimate arms across plants; other automakers followed within a decade.
Automotive became the dominant robot market for 60 years, a position it still holds today.
The 5-million milestone is the endpoint of a 65-year arc that began with a single robotic arm lifting die castings at GM.
