What type of machine did Leonardo da Vinci design with a humanoid body and movable limbs?

Leonardo da Vinci designed a mechanical knight with a humanoid body and movable limbs.

The machine was created around 1495 for a Milanese court celebration or related display. Leonardo’s drawings show an armored figure operated by an internal system of gears, cables, and pulleys. The mechanism was intended to make the figure sit, stand, and move its arms, creating the appearance of an artificial knight.

It was not a robot in the modern electronic sense. The machine had no computer, sensors, or electric motor; its actions came from Renaissance mechanical engineering. Because Leonardo’s surviving notes are incomplete, modern reconstructions have interpreted some details differently.

The mechanical knight demonstrates how Leonardo applied his studies of human anatomy and movement to automata. It is also distinct from his mechanical lion, another celebrated design associated with court spectacle and symbolic display.
