What name is given to Leonardo da Vinci’s mechanical warrior?

Leonardo da Vinci’s mechanical warrior is commonly called Leonardo’s robot.

Leonardo designed the machine around 1495 for a pageant in Milan, probably under the patronage of Ludovico Sforza. It was intended to resemble a medieval armored knight. Internal cables, pulleys, and gears allowed it to sit, stand, raise its arms, and move its head and jaw.

The surviving evidence is mainly a series of sketches and notes rather than a complete original machine. In the 1950s, researchers studying Leonardo’s Codex Madrid discovered drawings that helped clarify how the mechanisms might have worked. The machine therefore belongs to the history of automata, not to modern robotics with electronic sensing or software.

In 2002, Mark Rosheim built a full-scale model based on Leonardo’s plans and demonstrated it publicly. The reconstruction helped show that the knight’s movements were mechanically plausible. Its popular label “robot” is modern; Leonardo himself would have treated it as an automaton or mechanical device.
