Robots: There are over 200,000 robots are in use in Japan alone. In India there are just over 10000 robots are in use, mainly due to availability of huge manpower. But it is expected that the number of robots employed in India also will increase considerably as the demand for higher productivity and quality is fully realised by the Indian industries nowadays, especially in the automobile sector. Lights off manufacturing is a new method where the production is done without any manpower and it is practised in Japan now.
