41 years ago today, April 9th, 1984 (March 9th, 1984), Japan built the world's first "no-working factory". April 9th, 1984, the world's first experimental "no-working factory" was built in Japan, and began its trial operation. The trial operation proved that the latest machinery controlled by a hundred skilled workers and electronic computers, took two weeks to manufacture small gear engines, diesel and other machines, and now only four workers spent a day to manufacture no-working factory" with various processing tools that can be automatically switched. From the processing parts to the assembly to the final finished product inspection, can be completed automatically without a person. This success will further accelerate the "factory automation" process of the entire manufacturing industry. This project is co-operated
