The Zhang Heng odometer, invented by the Chinese polymath Zhang Heng in the 2nd century, operates using a system of gears and a rotating wheel. As a vehicle travels, the wheel turns and drives a series of gears that activate a mechanism to drop a ball into one of several receptacles. Each receptacle corresponds to a specific distance traveled, allowing the user to measure the distance accurately. This innovative design provided a way to track distances without manual counting, enhancing navigation and transportation efficiency.
