What Leonardo da Vinci automaton was designed as a seated, armored human figure?

Leonardo da Vinci’s robotic knight was an automaton designed as a seated, armored human figure.

Leonardo developed the design in Milan around 1495, probably for a pageant or court spectacle sponsored by Ludovico Sforza. The knight’s internal system of cables, pulleys, and gears was intended to reproduce human-like movements, including raising its arms and moving its head and jaw.

The original machine has not survived, and Leonardo’s surviving drawings do not provide a complete construction manual. In 2002, roboticist Mark Rosheim built a working model based on Leonardo’s sketches and notes, demonstrating that the mechanism could perform several movements.

The device is often called Leonardo’s robot, but that label is modern. It was a mechanical automaton, not an autonomous robot in the contemporary electronic or computer-controlled sense. Its importance lies in Leonardo’s study of anatomy translated into mechanical motion.
