Leonardo's robot or Leonardo's mechanical knight refers to a humanoid automaton designed by Leonardo da Vinci around the year 1495.[1]

The design notes for the robot appear in sketchbooks that were rediscovered in the 1950s.[1] Leonardo displayed his "robot" at a celebration hosted by Ludovico Sforza at the court of Milan in 1495. The robot knight could stand, sit, raise its visor and independently maneuver its arms. The entire robotic system was operated by a series of pulleys and cables. Since the discovery of the sketchbook, the robot has been built faithfully based on Leonardo's design; this proved it was fully functional, as Leonardo had planned.[2]

The robot is clad in German-Italian medieval armor, and is able to make several human-like motions. These motions included sitting up and moving its arms and neck, and it had an anatomically correct jaw. It is partially the fruit of Leonardo's anatomical research in the Canon of Proportions as described in the Vitruvian Man.

Beginning in the 1950s, investigators at the University of California began to ponder the significance of some of da Vinci's markings on what appeared to be technical drawings ... It is now known that da Vinci's robot would have had the outer appearance of a Germanic knight.
