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.
Robotic art
Advances in engineering created new possibilities for robotic art. In 1893, Prof. George Moore created "The Steam Man", a humanoid mechanism powered by a boiler, which he exhibited in New York City. Supported by a horizontal bar attached to a vertical post, it was capable of walking in a circle at a speed of four or five miles an hour; reportedly, it could not be held back by two men. In 1898, the physicist and engineer Nikola Tesla demonstrated a remote-controlled boat in Madison Square Garden, making use of a specially built indoor pond. This device has been identified as the world's first radio-controlled vessel. Tesla described it as having "a borrowed mind", and envisioned a fleet of fifty or a hundred submarines, or any other kind of vehicle, under the command of one or several operators.
