query: Who invented the first robot?
passage: Robot
In 1928, one of the first humanoid robots, Eric, was exhibited at the annual exhibition of the Model Engineers Society in London, where it delivered a speech. Invented by W. H. Richards, the robot's frame consisted of an aluminium body of armour with eleven electromagnets and one motor powered by a twelve-volt power source. The robot could move its hands and head and could be controlled through remote control or voice control.[44] Both Eric and his "brother" George toured the world.[45]
passage: Social robot
While robots have often been described as possessing social qualities (see for example the tortoises developed by William Grey Walter in the 1950s), social robotics is a fairly recent branch of robotics. Since the early 1990s artificial intelligence and robotics researchers have developed robots which explicitly engage on a social level. Notable researchers include Cynthia Breazeal, Tony Belpaeme, Aude Billard, Kerstin Dautenhahn, Yiannis Demiris, Hiroshi Ishiguro, Maja Mataric, Javier Movellan, Brian Scassellati and Dean Weber. Also related is the Kansai engineering movement in Japanese science and technology --- for social robotics, see especially work by Takayuki Kanda, Hideki Kozima, Hiroshi Ishiguro, Micho Okada, Tomio Watanabe, and P. Ravindra S. De Silva.
