What humanoid automaton did Leonardo da Vinci design for a Milanese court celebration in 1495?

Leonardo da Vinci’s 1495 humanoid automaton is known as Leonardo’s robot.

Leonardo designed the machine in Milan, probably for a court pageant or celebration associated with Ludovico Sforza. It was dressed in armor and could perform human-like movements, including sitting, standing, moving its arms, and moving its jaw. These actions were driven by cables and mechanical linkages inside the armor.

The robot was not an electronic machine and did not have artificial intelligence. “Robot” is a modern label applied because the device could operate mechanically and imitate a person. Its design was reconstructed from drawings and notes discovered in the Codex Atlanticus and related studies.

A full-scale reconstruction by Mark Rosheim was displayed in 2002. The machine demonstrates Leonardo’s interest in anatomy, mechanics, theater, and the controlled transmission of motion through gears, pulleys, and cables.
