Leonardo da Vinci designed a mechanical humanoid known as the robot knight for a Milanese pageant in 1495.
The machine was created for festivities organized by Ludovico Sforza, Leonardo’s patron in Milan. Leonardo’s surviving notes and drawings show a knight in armor whose internal cables and pulleys could produce human-like movements, including sitting, standing, and moving its arms. The mechanism was operated by a system of cranks and cables rather than by electricity or digital control.
The robot is often described as the first humanoid robot in Western history. That claim refers to the surviving design and its mechanical behavior, not to a modern autonomous robot. No original machine is known to survive, and the exact performance of the historical version remains uncertain.
In 2002, roboticist Mark Rosheim built a working reconstruction based on Leonardo’s drawings. The project helped demonstrate that the design’s articulated movements were mechanically plausible.
