Sony is predicting that robots will take over its manufacturing lines of televisions, smartphones and cameras as the entertainment conglomerate shifts its attention to services to drive sales of consumer electronics devices. Kimio Maki, head of Sony's electronics businesses, said that installing unmanned production lines was expected to cut costs 70 per cent at Sony's mainstay TV factory in Malaysia by the fiscal year 2023, compared with 2018. The group also has ambitions of using robotics in smartphone and camera manufacturing in the future, although it will maintain some factory workers.
