Can wall-climbing robots and AI that learns from master craftsmen close the gap?Car plants are full of robots, yet ships are still mostly built by hand. Japan has now decided to build about twice as many ships by 2035, and at today's productivity it would be about 60,000 workers short. DATA TIMES collected 72 robot and AI projects at Japanese shipyards and 28 shipyard tech job postings to show why ships are so hard for robots, how many robots are actually running, and how far Korea, China and the US are ahead, from wall-climbing quadrupeds to AI that learns from master craftsmen.
