What was Leonardo da Vinci's humanoid mechanical invention commonly called?

Leonardo da Vinci's humanoid mechanical invention is commonly called the mechanical knight. He designed it in Milan around 1495, probably for a festival or court performance sponsored by Ludovico Sforza.

The knight was enclosed in armour and could reportedly sit, stand, raise its arms, and move its head and jaw. A system of pulleys, cables, and gears inside the armour translated the motion of cams into movements resembling those of a human figure.

Leonardo's original working machine has not survived, and the design was reconstructed from notes and drawings discovered in the Codex Madrid manuscripts. In 2002, roboticist Mark Rosheim built a working model based on Leonardo's plans.

The mechanical knight is often labelled the first humanoid robot. That description is modern rather than a term Leonardo used, but the machine clearly demonstrates his interest in programmable-looking mechanical movement and theatrical automation.
