This model represents one of Leonardo da Vinci's most intriguing designs. It has been known as "Leonardo's Automobile" but recent studies consider it one of the first robots in history. The machine is drawn on folio 812/r/ of the Codex Atlanticus together with other devices. The robot's engine is hidden internally: a spring held fast by a stopping mechanism trasmits motion to the gears that move the wheels on the sides.
