We just learned about Leonardo da Vinci's Paris Manuscripts.
Another one of his famous inventions was called Leonardo's Robot.
Some time around 1495, Leonardo da Vinci came up with the idea to make a mechanical knight, that could move around.
He made some sketches on how to make it using pulleys and cables that were inside metal armor.
He showed it off to some people in Milan, and by pulling on cables he could make it stand, sit, and move its arms and head.
His robot has been lost, but some people have followed his designs and made copies of what they think his looked like long ago.
