Leonardo da Vinci’s robot was a life-sized mechanical knight powered by cables, pulleys, and gears. He designed it around 1495 for a pageant in Milan, probably under the patronage of Ludovico Sforza.
The armored figure could reportedly sit, stand, raise its arms, and move its jaw. Internal mechanisms translated motion from a hand-operated crank into coordinated movements. Leonardo’s knowledge of anatomy helped him arrange joints and linkages in a body-like structure.
No contemporary machine survives, and the original performance is not documented in detail. In 2002, roboticist Mark Rosheim built a working reconstruction from Leonardo’s drawings. The robot is important in robotics history because it demonstrates programmable mechanical movement centuries before electronic control systems.
