Masahiro Mori (森 政弘; Mori Masahiro, born 1927) is a Japanese roboticist noted for his pioneering work on the emotional response of humans to non-human entities, as well as for his views on religion and robots.

In 1970, Mori published “Bukimi No Tani” (不気味の谷 The Uncanny Valley) in Energy. The article forwarded the hypothesis that as robots become more humanlike, they appear more familiar until a point is reached at which subtle imperfections of appearance make them look eerie. The observation led Mori to the belief that robot builders should not attempt to make their creations overly lifelike in appearance and motion.

In 1974, Mori published The Buddha in the Robot: a Robot Engineer’s Thoughts on Science and Religion in which he discussed the metaphysical implications of robotics. In the book, he wrote “I believe robots have the buddha-nature within them—that is, the potential for attaining buddhahood.”^[1]

In 1988, Mori founded the first nation-wide robot-building competition in Japan and has widely promoted robot competitions in the years since then.^[2]

Mori is currently president of the Mukta Research Institute, which he founded in Tokyo in order to promote his views on religion and robots. The institute also provides consultation on the use of automation and robotics in industry.^[3]
