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.
I, Robot (short story)
The story is about a robot's confession. Some weeks earlier, its builder, Dr. Charles Link, built it in the basement. Link teaches his robot to walk, talk and behave civilly. Link's housekeeper sees the robot just enough to be horrified by it, but his dog is totally loyal to it. The robot is fully educated in a few weeks, Link then names it Adam Link, and it professes a desire to serve any human master who will have it. Soon afterwards, a heavy object falls on Dr. Link by accident and kills him. His housekeeper instantly assumes that the robot has murdered Dr. Link, and calls in armed men to hunt it down and destroy it. They do not succeed; in fact, they provoke the robot to retaliate, both by refusing to listen to it and by accidentally killing Dr. Link's dog. Back at the house, the robot finds a copy of "Frankenstein", which Dr. Link had carefully hidden from the robot, and finally somewhat understands the prejudice against it. In the end the robot decides that it simply is not worth killing several people just to get a hearing, writes its confession, and prepares to turn itself off.
