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.
Wu Yulu
In the late 1970s, Wu got a job at a farm machinery factory, and the small income helped him turn used sewing machine parts and some steel wire into his first robot. "Until now, I don't know the theory of physics, but I knew that electricity can drive motors and power can be transferred to the robot's hands and legs with levers and wires," Wu said. After his first robot turned out to be "disabled," Wu continued to experiment. In 1982, the first movable robot, Wu Laoda (the first son of the Wu), was born.
