What Leonardo da Vinci machine is considered an early mechanical knight?

Leonardo da Vinci’s robot knight is considered an early mechanical knight.

Leonardo designed the automaton around 1495 for a pageant in Milan organized under the patronage of Ludovico Sforza. The armored figure was powered by an internal system of pulleys, cables, and gears. Reconstructions based on Leonardo’s notes suggest that it could sit, stand, move its arms, and operate its jaw.

The machine was not a programmable robot in the modern electronic sense. It had no computer, sensors, or artificial intelligence. Its movements came from mechanical linkages controlled by an operator or by preset mechanisms. “Robot” is therefore a modern label for a Renaissance automaton.

The original device has not survived, and historical evidence about the performance is limited. In 2002, roboticist Mark Rosheim built a reconstruction based on Leonardo’s drawings. The project helped demonstrate that the concept could work mechanically, while still leaving uncertainty about the exact original version.
