11 Predictions From Leonardo da Vinci That Actually Came True
The Italian polymath from the Renaissance era, best known for his works of art like the "Mona Lisa" and "The Last Supper," was also a prolific inventor and avid researcher. Da Vinci's natural genius and relentless scientific curiosity led him to fill countless notebooks with sketches, inventions, observations about the world, and theories — many of which were later found to be true.
Da Vinci designed what may have been the very first humanoid robot. The inventor's "armored knight" was capable of sitting up, waving its arms, moving its head, and opening and closing its jaw. This robotic knight was made up of a knight suit that was filled with gears and wheels connected to a pulley and cable system, enabling the primitive "robot" to move on its own.
