At a factory south of Toyota City, Aichi Prefecture, robots have started sharing the work of quality-control inspectors, as the coronavirus pandemic accelerates a shift from Toyota's vaunted "go and see" system which helped revolutionize mass production in the 20th century.
Inside the auto-parts plant of Musashi Seimitsu Industry Co. Ltd., a robotic arm picks up and spins a bevel gear, scanning its teeth against a light in search of surface flaws. The inspection takes about two seconds — similar to that of highly trained employees who check around 1,000 units per shift.
"Inspecting 1,000 of the exact same thing day-in day-out requires a lot of skill and expertise, but it's not very creative," Chief Executive Hiroshi Otsuka said. "We'd like to release workers from those tasks."
