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.
Susan Calvin
According to Asimov's fictional history of robotics, Susan Calvin was born in 1982, the same year that US Robots and Mechanical Men was incorporated. At 16, she wrote the first of many papers on robotics, a Physics-1 paper entitled "Practical Aspects of Robotics". This was after attending a Psycho-Math seminar at which Dr Alfred Lanning of US Robots demonstrated the first mobile robot to be equipped with a voice. As quoted in "I, Robot"; "Susan said nothing at that seminar; took no part in the hectic discussion period that followed. She was a frosty girl, plain and colorless, who protected herself against a world she disliked by a mask-like expression and a hypertrophy of intellect. But as she watched and listened, she felt the stirrings of a cold enthusiasm".
