I am convinced that a genius like Leonardo could have developed studies on new machines that imitated man and his structure with their mechanisms. When he was examining parts of the human body, perhaps the idea of making some project occurred to him. After all, he also loved experimenting with machines and what better thing than to combine the two passions? We don’t know and maybe it was too early for humanity. What could he and many other geniuses of the past have invented if they had worked in this direction? It is now easy for me to examine this project and so I tried to make hypotheses and drawings as if all this had really happened.
