Nikkei BOOK Plus publishes article on why humanoid robots are being developed

Nikkei BOOK Plus published an article on Nov. 5, 2026, about why humanoid robots are being developed.

The article is an explanatory piece excerpted and reworked from a book; it does not report company development announcements or provide evidence of robots in operation. It is important to distinguish explanations about humanoid robots from evidence of specific deployments or operations.

This article is not about announcements or experimental results from robotics companies, but an explanatory piece excerpted and reworked from a book. Its publication therefore cannot be taken as evidence of companies’ development decisions or of robots operating in the field. See the original source for more details on the article published by Nikkei BOOK Plus. A related article from this newspaper introduces a guide comparing humanoids with autonomous mobile robots (AMRs), but its publication is not an announcement of a specific company’s deployment. The comparison guide on warehouse automation provides information for comparing options, while this explanatory article is a feature about the background to development; they serve different purposes. Neither shows which tasks a particular robot performs or what results it has achieved. When assessing robots in operation, it is important not to confuse fundraising activity or explanations of why robots are being developed with operating records. Regarding a Bloomberg report on fundraising trends in China’s robotics sector, this newspaper noted that funding amounts alone cannot establish business progress or how funds are allocated among companies. Report on a slowdown in fundraising in China’s robotics sector. Meanwhile, a proposal for “Worken,” a metric for measuring robot activity, relates to the discussion of how operations are evaluated, but the article does not clarify how the formula is measured or applied to pricing. Proposal for “Worken,” a metric for measuring robot activity. Explanations of background, funding and operational metrics address different questions. To connect explanations of development rationales to an assessment of actual business activity, future reporting should clarify the tasks and deployment conditions, as well as the measures being evaluated and how they are measured, such as the number of robots in operation, autonomous operating hours and output efficiency ratios. These are not facts that can be confirmed from this article, but verification points based on issues raised in related articles. Rather than extending the article’s explanations into claims about individual companies’ performance or overall market trends, readers should separately verify the evidence behind announcements, deployments and measurements.
