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.
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.
