Hiroshi Ishiguro's laboratory · research humanoid

ibuki

A child android styled after a 10-year-old boy that rolls on wheels yet moves its upper body to look as if it is walking; built for research with no fixed commercial use. The launch report names the lab as an 'Intelligent Robotics Laboratory, Wakayama University', which conflicts with other descriptions of Ishiguro's lab.
