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. Both Eric and his "brother" George toured the world.
Computer art
One of the first robot painters was AARON, an artificial intelligence/artist developed by Professor Harold Cohen, UCSD, in the mid-1970s. Another pioneer in the field, Ken Goldberg of UC Berkeley created an 11' x 11' painting machine in 1992. Multiple other robotic painters exist though none are currently mass-produced.
