What mechanical device did Leonardo da Vinci design to imitate human walking and movement?

Leonardo da Vinci designed a mechanical knight to imitate human walking and movement.

The automaton was created around 1495 for a pageant or celebration connected with the court of Ludovico Sforza in Milan. Leonardo’s drawings show a suit of armor containing a system of gears and mechanisms. The figure could reportedly sit, stand, and move its arms, although the surviving evidence comes from designs and later reconstruction rather than a fully preserved original machine.

The device is often called Leonardo’s robot, but it was a mechanical automaton, not an electronic robot in the modern sense. It worked through mechanical power, linkages, and programmed movement.

In 2002, roboticist Mark Rosheim built a working reconstruction based on Leonardo’s notes. That reconstruction helped demonstrate that the design could produce several of the movements suggested by the drawings, while also showing how much interpretation is required when reconstructing incomplete Renaissance plans.
