Hiroshi Ishiguro (born 1963) is a Japanese roboticist and Distinguished Professor at Osaka University. A world-leading pioneer in humanoid android robotics, he is best known for developing lifelike robots, including the Geminoid series modeled on himself, to explore the fundamental question of what it means to be human. His best-known book, "Robotto to wa Nanika: Hito no Kokoro o Utsusu Kagami" ("What Is a Robot?: A Mirror Reflecting the Human Mind"), examines how research on humanoid robots can deepen our understanding of the human mind, the body, communication, and the future relationship between humans and machines.
