After reaching the maximum reading, an odometer or trip meter restarts from zero, called odometer rollover. Digital odometers may not rollover. [16] Most modern cars include a trip meter (trip odometer). Unlike the odometer, a trip meter is reset at any point in a journey, making it possible to record the distance traveled in any particular ...
The roadometer was a 19th-century device like an odometer for measuring mileage, mounted on a wagon wheel. One such device was invented in 1847 by William Clayton, Orson Pratt, and Appleton Harmon, pioneers of the Church of Jesus Christ of Latter-day Saints.
An odometer for measuring distance was first described by Vitruvius around 27 and 23 BC, although the actual inventor may have been Archimedes of Syracuse (c. 287 BC – c. 212 BC). It was based on chariot wheels turning 400 times in one Roman mile. For each revolution a pin on the axle engaged a 400 tooth cogwheel, thus turning it one complete ...
Archimedes has also been credited with improving the power and accuracy of the catapult, and with inventing the odometer during the First Punic War. The odometer was described as a cart with a gear mechanism that dropped a ball into a container after each mile traveled.
Some vehicles manufactured from the late 1990s to mid 2000s have a MIL that illuminates based on the odometer reading, regardless of engine operation. For example, in several Mazda models, the light will come on at 80,000 miles (130,000 km) and remain lit without generating a computer trouble code.
Clayton, along with Orson Pratt and Appleton Milo Harmon, created a novel design for a wooden odometer for use on wagons, also called a roadometer. [35]: 86–90 Clayton was assigned to record the number of miles the company traveled each day. One day, Clayton personally counted the revolutions of a wagon wheel and computed the day's distance ...
Five digit odometer of a Citroën Acadiane, 1986. Odometry is the use of data from motion sensors to estimate change in position over time. It is used in robotics by some legged or wheeled robots to estimate their position relative to a starting location. This method is sensitive to errors due to the integration of velocity measurements over ...
The origins of the surveyor's wheel are connected to the origins of the odometer. While the latter is derived to measure distances travelled by a vehicle, the former is specialized to measure distances. In the 17th century, the surveyor's wheel was re-introduced and used to measure distances.
