If it initially points exactly to the south, at the end of the one-kilometre trip it will point almost to the Considerable scepticism is therefore warranted as to whether this type of south-pointing chariot, using a differential gear for the whole time, was used in practice to navigate over long distances. The charioteer could have kept the stationary wheel from turning by controlling the horses appropriately. The south-pointing chariot was an ancient Chinese two-wheeled vehicle that carried a movable pointer to indicate the south, no matter how the chariot turned. There are several methods that could have been used, for example: If the chariot was turning, the pointing doll was connected by gears to one or other of the two main road wheels (e.g. 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. If a third road wheel was included, this type of south-pointing chariot could have worked quite accurately as a compass when used for short journeys under good conditions, but if used for long journeys it would have been subject to cumulative errors, like chariots using the differential mechanism. If (instead) it turns (and goes) westwards, the (back end of the) pole is pushed to the left; the subordinate wheel attached to the left road-wheel will turn forward with the road-wheel 12 teeth, drawing with it the left small horizontal wheel one revolution, and pushing the central large horizontal wheel to revolve a quarter turn to the right. The carriage wheels were 5.7 ft. in diameter, the In the lower story were 13 wheels. The ancient descriptions are often unclear, but they suggest that the Chinese implemented several different designs, at least some of which did not include differentials.

The chariot was supposedly used as a compass for navigation and may also have had other purposes. Usually, the pointer took the form of a doll or figure with an outstretched arm. The ancient Chinese chariot design has a pointer which always points in the same direction -irrespective of how the chariot moves. Some of the ancient descriptions suggest that some south-pointing chariots could move in only three ways: straight ahead, or turning left or right with a fixed radius of curvature. Each of the lower component gears was 2.1 ft. in diameter and 6.3 ft. in circumference, with 32 teeth, at intervals of 2.1 inches apart. If in fact there was no third road wheel, the chariot might have functioned as a compass if turns were always made so that one of the two wheels was stationary and only the other rotated, with the pointing doll connected to it by gears. If turns were brief and rare, this would have greatly reduced the pointing errors, since they would have accumulated only during the short periods when the doll and differential were connected. Considering that a large mechanical wagon or chariot would be obligated to travel on roads, the destination in question would typically not be in an unknown direction.
That lets your car go around turns, where the inner wheel will travel less distance than the outer wheel. These methods can work accurately over long distances, unlike the mechanical designs for the chariot. Conceivably, the south-pointing doll was fixed to the body of the chariot while it was travelling in straight lines, and coupled to the differential only when the chariot was turning. Someone riding inside the chariot may have used some non-mechanical method of determining the compass directions, and turned the doll on top of the chariot accordingly. South dealing with home is one during which the primary entrance door opens on to the south.As indicated by Vastu Shastra, all course impression equally home Vastu, nevertheless, the first passage must be within the north or east-facing course for essentially the most excessive benefit of the household. Differential gears. In the middle was the largest horizontal wheel, 3.8 ft. in diameter, 11.4 ft. in circumference, and having 100 teeth at intervals of 2.1 inches apart. Some non-mechanical method of finding the south must have been used when a mechanical south-pointing chariot was If any south-pointing chariot was really used for long-distance navigation, it must have relied (after initialization) on a non-mechanical direction-finding method. In a south-pointing chariot, according to the hypothesis, Shaft B was connected to one road wheel and Shaft C was connected The hypothesis that there were south-pointing chariots with differential gears originated in the 20th century.
