When you hear the name Leonardo Da Vinci, do you imagine the famous painting called Mona Lisa? Yes, Leo was a great artist, but he wasn't just great at art. He was a brilliant inventor and an extraordinary architect. He invented vehicles and machines far ahead of his time. His notebook contained many designs of machines and vehicles. Leo was interested in human anatomy and spent countless hours dissecting cadavers to discover how humans functioned. This gave him an idea of ​​how certain muscles moved certain bones. Leonardo thought these things could be applied to a machine. Unlike most of Leo's inventions, Leo apparently actually built the robotic knight. “If Leonardo's self-propelled chariot had been the first working design of a robotic vehicle, then the robotic knight would have been the first humanoid robot, a real 15th century C-3PO,” says Christopher Lampton. The knight didn't survive long enough for people to know exactly what it did, but based on Leo's writings, scientists have an idea of ​​how it worked. The wooden robot was apparently able to sit, move and even use its jaw. His writings note that it was driven by pulleys and gears. In 2002, a robotics expert named Mark Rosheim used Da Vinci's notes to recreate it. Some concepts were used by Rosheim to create designs for robots in planetary exploration. Who knows, if the robot had been mass-produced, robotics today would have been more advanced than it is now. But a wooden robot was not Da Vinci's only invention. He also created a design for a tank that would be devastating in war. While working for Ludovico Sforza, Leo proposed what might have been his most lethal war machine of its time: the arm... in the center of the paper... the moving machine in Leo's notebooks was an interesting project for a self-propelled car. The drawings drawn in his notebooks do not actually show the mechanism inside. So engineers today had to guess what made it move. The best guess is that the mechanism used was just like the mechanism of a clock. But for some strange reason Da Vinci didn't create the machine. Leo thought what he had drawn was just a toy, but it wasn't. if it had been created, machine applications would have followed. Long story short, Da Vinci was an incredibly brilliant man. His inventions would completely change the course of history. Today's school textbooks might have said something about the steampunk era that might have existed if Leo's inventions had been mass-produced. The war, the cities, the escape and everyday life would have been very different from how we know them today.
