What robotic figure did Leonardo da Vinci design around 1495 for a Milanese court celebration?

Leonardo da Vinci designed a mechanical knight around 1495 for a Milanese court celebration.

The automaton was commissioned by Ludovico Sforza, Duke of Milan, and was probably intended for a pageant or festival. Leonardo's drawings show an armored figure operated by an internal system of gears, cables, and pulleys. The mechanism could reportedly make movements such as sitting, standing, and moving its arms, although the exact original performance remains uncertain.

The machine was not an autonomous robot in the modern electronic sense. It was a mechanical automaton powered by physical linkages and possibly hand operation. Leonardo's anatomical studies helped him think about how joints and limbs could move within an armored body.

No original mechanical knight has survived. In the early 2000s, engineers built reconstructions based on Leonardo's drawings and demonstrated that the mechanism was feasible. The design is therefore important both as an early automaton concept and as evidence of Leonardo's close connection between engineering and anatomy.
