  2. Odometry - Wikipedia

    en.wikipedia.org/wiki/Odometry

    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 ...

  3. Odometer - Wikipedia

    en.wikipedia.org/wiki/Odometer

    An odometer or odograph is an instrument used for measuring the distance traveled by a vehicle, such as a bicycle or car. The device may be electronic, mechanical, or a combination of the two ( electromechanical ).

  4. Tachometer - Wikipedia

    en.wikipedia.org/wiki/Tachometer

    Slotted-disk devices are typical sensors used in odometer systems for rail vehicles, such as are required for train protection systems — notably the European Train Control System. As well as speed sensing, these probes are often used to calculate distance travelled by multiplying wheel rotations by wheel circumference.

  5. Roadometer (odometer) - Wikipedia

    en.wikipedia.org/wiki/Roadometer_(odometer)

    A machine commonly displayed as Clayton's odometer is actually one built in 1876 by Thomas G. Lowe. Lowe created his odometer to calculate the distance between villages in northern Arizona. He gave his odometer to the Deseret Museum in Salt Lake City, and it was on display with accurate information from 1876 until it closed for a period in 1903 ...

  6. Tachograph - Wikipedia

    en.wikipedia.org/wiki/Tachograph

    This includes the drivers name, the date(s) the disc refers to, the start and end odometer readings and the registration mark of the vehicle. Three traces are made in the wax surface by the head. These traces are either made by three separate styli or a single multipurpose stylus. The trace closest to the centrefield is the distance trace. The ...

    Hubodometer Veeder-Root Hubodometer Veeder-Root Original Veeder Counter Veeder Company Cyclometer Poster 1900. A hubometer (from hub, center of a wheel; -ometer, measure of) or hubodometer, is a device mounted on the axle of any land vehicle to measure the distance traveled by a vehicle based on the rotations of the wheel hub.

  8. Speedometer - Wikipedia

    en.wikipedia.org/wiki/Speedometer

    A speedometer showing mph and km/h along with an odometer and a separate "trip" odometer (both showing distance traveled in miles) The amended Road Vehicles (Construction and Use) Regulations 1986 permits the use of speedometers that meet either the requirements of EC Council Directive 75/443 (as amended by Directive 97/39) or UNECE Regulation 39.

  9. Surveyor's wheel - Wikipedia

    en.wikipedia.org/wiki/Surveyor's_wheel

    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.
