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.

In the thirteenth century AD, Badi Al-Zaman'Isma'il Al-Razzaz Al-Jazari was a Muslim inventor who devoted himself to mechanical engineering. Like Hero, he experimented with water clocks and other hydraulic mechanisms. Al-Jaziri’s life's work culminated in a book which he called "The Book of Knowledge of Ingenious Mechanical Devices", completed in 1206 AD, and often known simply as "Automata". In Europe, also in the thirteenth century, Villard de Honnecourt is known to have built mechanical angels for the French court, and in the fifteenth century Johannes Muller built both a working mechanical eagle and a fly.
