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.

Among the vast number of projects of Leonardo, there is a “mechanical knight” that has entered into the common imagination. In 1957 Carlo Pedretti was the first person to discover it, hidden amongst da Vinci’s countless designs. The mechanical knight was again mentioned in 1974, in the Codex Madrid edited by Ladislao Reti. Nevertheless, there was no attempt to reconstruct it until 1996. It was then that Mark Rosheim published an independent study of the robot, followed by a joint enterprise with the Florence Institute and Museum of the History of Science which mounted an exhibition with an entire section dedicated to Rosheim’s research on the subject. However, it was only in 2002 that Rosheim built a complete physical model for a BBC documentary. Since then, many exhibitions and museums of da Vinci’s models have included a soldier on wheels labeled, “Leonardo’s robot”.
