Abstract

This paper shows the international comparisons of industrial robot penetration. The results of comparisons are summarized as follows: (a) There is a big gap of robot density between the leading country, Japan and other major developed market economy countries. (b) However, the penetration trend curves show a very similar pattern among those countries. (c) Therefore, the differences of I.R. penetration can be expressed by introducing a time-lag for each country. The time-lag of other countries are estimated by regression analysis for multi-national time-series data, resulting in a figure of 4.4 to 7.8 years behind Japan. (d) With regard to the application and industrial distribution of I.R., remarkable differences are found between Japan and other countries, namely, with regard to assembly robots in the Japanese electric/electronics industry as opposed to welding robots in the automotive industry of other countries.
