Leonardo's robot

Leonardo's robot, or Leonardo's mechanical knight (Italian: Automa cavaliere, lit. "Automaton knight"), is a humanoid automaton designed and possibly constructed by Leonardo da Vinci in the late 15th century.

The robot’s design largely consists of a series of pulleys that allow it to mimic human motions. Operational versions of the robot have been reconstructed by multiple researchers after the discovery of Leonardo’s sketches in the 1950s. Leonardo’s designs may have served as inspirations for robotics projects backed by NASA and Intuitive Surgical.
