Prof. Hiroshi Ishiguro has been doing research on teleoperated robots, for more than two decades. In his research, he developed a series of avatars, called Geminoids, which resemble himself. The study not only helps to understand humans and apply methods from engineering, cognitive science and neuroscience to various research topics, but also practically allows a person to be physically present and work in different places without travelling. The talk will introduce research and development of teleoperated androids, such as Geminoids, and discuss how humans and robots can coexist in future society.
