The “points of development” are clearly stated for each stage leading to the nal commercialization, and the technical progress is described comprehensibly. In addition to technological hurdles, the ways in which unexpected hurdles such as the re-organization of the research institute and the Lehman Shock were surmounted are described, which makes this paper very thought-provoking.Comment (Ken’ichi Fujii, AIST)This research is very valuable on the point that automated
