The odometer, from the ancient Greek meaning “path measure,” has evolved from mechanical to electronic devices used to measure distance in vehicles like automobiles and bicycles. Scholars like Vitruvius, Hero of Alexandria, and Leonardo da Vinci studied and designed odometers throughout history. Vitruvius’ odometer used a gear coupling system and a toothed wheel to measure miles traveled. Leonardo da Vinci’s odometer designs showcased his innovative thinking, including a dual-wheel system and intricate gear mechanisms. The Fano Exhibition highlighted the influence of Vitruvius on Leonardo’s work, showcasing original drawings and digital reconstructions of their machines. Leonardo’s redesign of Vitruvius’ odometer demonstrated his engineering prowess and problem-solving skills.
