When it has turned round 12 teeth, the carriage moves due west, but still the wooden figure stands crosswise and points south. The ancient Chinese invented a mobile-like armored cart in the 5th century BC called the There are legends of earlier south-pointing chariots, but the first reliably documented one was created by the Chinese mechanical engineer There were probably several types of south-pointing chariot which worked differently. On each of the road-wheels of the carriage, left and right, was a vertical wheel 2.2 ft. in diameter, 6.6 ft. in circumference, with 32 teeth at intervals of 2.25 inches apart. It might have been attached to the pole to which the horses were harnessed. If the real purposes of the chariot and the accounts of it were amusement and impressing visiting foreigners, rather than actual long-distance navigation, then its inaccuracy might not have been important. If the chariot was turning, the pointing doll was connected by gears to one or other of the two main road wheels (e.g. Even initialization could have been avoided by simply declaring some arbitrary direction to be "south". In order to counter Chi You’s fog, the Yellow Emperor had his minister, Feng Hou, invent the south-pointing chariot. As a navigator device, the south-pointing chariot would not have been quite accurate, unless it was regularly adjusted to correct the errors that arose over time.
The story goes that the Yellow Emperor was at war with Chi You, the leader of the Nine Li tribe.
This description, which may be found in the Based on the technical description of Yan Su and Wu Deren’s south-pointing chariot, scholars are able to have an understanding of the way this device worked.
Simple geometry shows that if the chariot's mechanism is based on a differential gear and if, for example, the width of the track of the chariot (the separation between its wheels) is three metres, and if the wheels are intended to be identical but actually differ in diameter by one part in a thousand, then if the chariot travels one kilometre in a straight line, the "south-pointing" figure will rotate nearly twenty degrees. However, it raises the problem of how the chariot could have been kept travelling in straight lines with sufficient accuracy without using the pointing doll.
Mathematically the device performs The chariot can be used to detect straight lines or Real machines are never built perfectly accurately. When it runs (and goes) eastwards, the (back end of the) pole is pushed to the right; the subordinate wheel attached to the right road-wheel will turn forward 12 teeth, drawing with it the right small horizontal wheel one revolution (and so) pushing the central large horizontal wheel to revolve a quarter turn to the left.
Putting such a wheel on the chariot and making it function properly would not have been difficult.
