Local robotics firms will accelerate the development of autonomous robots, as cleared by the recent passage of a bill authorizing high-tech robots to use sidewalks for delivery, patrol, information providing and cleaning services, according to market watchers, Tuesday. Further anchoring their business prospects is a robust industrial outlook, as indicated by International Federation of Robotics (IFR) data which estimated the size of the industrial and services robot market to surpass $50 billion (67 trillion won) by 2025, up from $30 billion in 2021, growing 17 percent a year.
