Robots are being used in China to replace human workers who are demanding higher wages.
A factory which produces lenses for the German company Carl Zeiss assigned the automated tasks to the robotic workers include applying protection films, cutting, polishing and packaging.
The factory’s manager explained that the change came as a solution to increase productivity. The installation of machines to carry out the tasks has seen the workforce shrink from 440 workers - who were producing four million lenses every year - to 370 humans in 2015 - with output increased to five million. "We used to have 60 workers in one shift but now we only need 48. And they’re only responsible for quality control and machine maintenance," he explains.
