Singapore and Korea are second and third respectively on the chart, but significantly behind Japan in numbers [illustration by Mike Vella; more on IEEE]

“Japan has highest industrial robot density”
why am i not surprised? =P
I doubt anyone would be surprised that Japan is on top… I was a bit surprised though, that Singapore actually came second on the chart.
you should visit singapore and see. labor cost so high here, and population low… we need a lot of machines and robots to replace the human labor.
