The Draughtsman
Made between 1772 and 1774, mainly by Henri-Louis Jaquet-Droz and Jean-Frédéric Leschot, The Draughtsman is an automaton capable of producing four different drawings: a portrait of Louis XVI, Marie-Antoinette, a dog and a Cupid driving a chariot drawn by a butterfly. The Draughtsman works by using a system of cams to that allow the hands to move in the three dimensions required to make a drawing. Thanks to a small air pump concealed in the head of the automaton, he periodically blows on his drawing to remove shards of lead pencil.
