Robot
Walter stressed the importance of using purely analogue electronics to simulate brain processes at a time when his contemporaries such as Alan Turing and John von Neumann were all turning towards a view of mental processes in terms of digital computation. His work inspired subsequent generations of robotics researchers such as Rodney Brooks, Hans Moravec and Mark Tilden. Modern incarnations of Walter's "turtles" may be found in the form of BEAM robotics.
The first digitally operated and programmable robot was invented by George Devol in 1954 and was ultimately called the Unimate. This ultimately laid the foundations of the modern robotics industry. Devol sold the first Unimate to General Motors in 1960, and it was installed in 1961 in a plant in Trenton, New Jersey to lift hot pieces of metal from a die casting machine and stack them. Devol's patent for the first digitally operated programmable robotic arm represents the foundation of the modern robotics industry.
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.
