The Automaton Knight (also known as Leonardo’s Robot) is a humanoid robot designed by Leonardo da Vinci between 1495 and 1497, in order to animate the festivities at the court of Milan of Ludovico Sforza.

There aren’t news that was ever actually built. However, since 1996 there have been numerous reproductions made especially by museums.

The description of this automaton was found in the Codex Atlanticus (a collection of drawings and writings by Leonardo da Vinci) and is considered the first draft of a humanoid robot in history.
