Gyrocar
A gyrocar is a two-wheeled automobile. The difference between a bicycle or motorcycle and a gyrocar is that in a bike, dynamic balance is provided by the rider, and in some cases by the geometry and mass distribution of the bike itself, and the gyroscopic effects from the wheels. Steering a motorcycle is done by precessing the front wheel. In a gyrocar, balance was provided by one or more gyroscopes, and in one example, connected to two pendulums by a rack and pinion. The concept was originally described in fiction in 1911 "Two Boys in a Gyrocar: The story of a New York to Paris Motor Race" by Kenneth Brown, (Houghton Mifflin Co). However the first prototype Gyrocar, The Shilovski Gyrocar, was commissioned in 1912 by the Russian Count Pyotr Shilovsky, a lawyer and member of the Russian royal family. It was manufactured to his design by the Wolseley Tool and Motorcar Company in England in 1914 and demonstrated in London the same year. The gyrocar was powered by a modified Wolse ...

Gyro Monorail
A gyro monorail, gyroscopic monorail, or gyro-stabilized monorail is a single-rail land vehicle that uses the gyroscopic action of one or more spinning wheels to overcome the inherent instability of balancing atop a single rail. For a similar steerable vehicle, see Gyrocar. The monorail is associated with the names Louis Brennan, August Scherl and Pyotr Shilovsky, who each built full-scale working prototypes during the early part of the twentieth century. A version was developed by Ernest F. Swinney, Harry Ferreira and Louis E. Swinney in the US in 1962. The gyro monorail was never developed beyond the prototype stage. The principal advantage of the monorail cited by Shilovsky is the suppression of hunting oscillation, a speed limitation encountered by conventional railways at the time. Also, sharper turns are possible compared to the multi-kilometre radius of turn typical of modern high-speed trains such as the TGV, because the vehicle will bank automatically on ben ...

Gyroscope
A gyroscope (from Ancient Greek γῦρος ''gŷros'', "round" and σκοπέω ''skopéō'', "to look") is a device used for measuring or maintaining Orientation (geometry), orientation and angular velocity. It is a spinning wheel or disc in which the axis of rotation (spin axis) is free to assume any orientation by itself. When rotating, the orientation of this axis is unaffected by tilting or rotation of the mounting, due to the angular momentum#Conservation of angular momentum, conservation of angular momentum. Gyroscopes based on other operating principles also exist, such as the microchip-packaged Vibrating structure gyroscope#MEMS gyroscopes, MEMS gyroscopes found in electronic devices (sometimes called gyrometers), solid-state ring laser gyroscope, ring lasers, fibre optic gyroscopes, and the extremely sensitive quantum gyroscope. Applications of gyroscopes include inertial navigation systems, such as in the Hubble Space Telescope, or inside the steel hull of a submer ...

Pyotr Shilovsky
Pyotr Petrovich Schilovsky () (September 22, 1872 – June 30, 1955 in Herefordshire) was a Russian count, jurist, statesman, and governor of Kostroma from 1910 to 1912 and of Olonets Governorate from 1912 to 1913. He is best known as the inventor of the gyrocar, which was built under his direction by the Wolseley Tool and Motorcar Company beginning in 1912, and was demonstrated for the first time in London in April 1914. In 1922, Schilovsky emigrated to the United Kingdom. File:Portrait of the governor of the Olonets province P. P. Shilovsky.jpg, P. P. Shilovsky in 1913 Gyrocar After developing a model gyro monorail in 1911, he designed a gyrocar which was built by Wolseley Motors Limited and tested on the streets of London in 1913. Since it used a single gyro, rather than the counter-rotating pair favoured by Brennan and Scherl, it exhibited asymmetry in its behaviour, and became unstable In dynamical systems instability means that some of the outputs or internal st ...

The Russian Two-wheel Car In London
''The'' is a grammatical article in English, denoting nouns that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pronoun ''thee' ...

Ford Gyron
The Ford Gyron was a futuristic two-wheeled gyrocar first shown to the world in 1961 at the Detroit Motor Show as a concept car designed by Syd Mead and McKinley Thompson. One wheel was at the front and the other at the rear like a motorcycle and the car was stabilized by gyroscopes. The two occupants of the vehicle were seated side by side and, when the vehicle was stationary, two small legs appeared from the sides to support it. The vehicle was created for research and marketing purposes, with no intention to put it into production. Alex Tremulis was the designer and the gyroscopic systems were based on Louis Brennan's theories. The Ford Motor Company of Detroit gave credit for the Gyron to Louis Brennan. Alex Tremulis had started his career with the US Air Force and worked in 1948 at the Wright-Patterson Air Force Base on the concept of Military flying saucers. He then became the chief designer for the ill-fated Tucker automobile before joining Ford, and was also involved with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lit Motors
Lit Motors Inc. is a San Francisco-based startup founded by Daniel K. Kim in 2010. Lit Motors designs conceptual two-wheeled vehicles with a focus on innovative technologies, including the AEV (Auto-balancing Electric Vehicle), often referred to as the "C-1," a fully electric, gyroscopically stabilized vehicle, and the Kubo cargo scooter. The inspiration for Lit Motors came to Kim in 2003, when he was injured by a chassis while manually assembling a bio-diesel Land Rover Defender 90. This experience led Kim to "chop a car in half," leading to the creation of the C-1 concept. Since 2011, the company has developed a number of prototypes, but as of July 2024, has not given an exact release date for a production model. Legal Issues Lit Motors has been sued by four early investors, resulting in approximately $300,000 in legal judgments against Lit Motors and an arrest order against Kim for failure to appear at court hearings related to these lawsuits. On January 7, 2020, a San ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Self-balancing Unicycle
An electric unicycle (often initialized as EUC or acronymized yuke or Uni) is a self-balancing personal transporter with a unicycle, single wheel. The rider controls speed by leaning forwards or backwards, and steers by twisting or tilting the unit side to side. The self-balancing mechanism uses accelerometers and gyroscopes. Most manufacturers of EUCs are based out of China, including Segway, Inmotion, Kingsong, Begode, and Leaperkim. Operation Similar to Self-balancing scooter, hoverboards, Onewheels, and Segways, electric unicycles are self-balancing in a forward and backward direction, with side-to-side (lateral) stability being provided by human steering motions that tilt or twist the unit, similar to Bicycle and motorcycle dynamics. The control of a unicycle can be considered to be similar to an inverted pendulum. Many electric unicycles have suspension, either operated by air or springs. Electric unicycles come in varying speeds, battery capacities, and motor wattages. L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bicycle And Motorcycle Dynamics
Bicycle and motorcycle dynamics is the science of the motion of bicycles and motorcycles and their components, due to the forces acting on them. Dynamics falls under a branch of physics known as classical mechanics. Bike motions of interest include balancing, steering, braking, accelerating, suspension activation, and vibration. The study of these motions began in the late 19th century and continues today. Bicycles and motorcycles are both single-track vehicles and so their motions have many fundamental attributes in common and are fundamentally different from and more difficult to study than other wheeled vehicles such as dicycles, tricycles, and quadracycles. As with unicycles, bikes lack lateral stability when stationary, and under most circumstances can only remain upright when moving forward. Experimentation and mathematical analysis have shown that a bike stays upright when it is steered to keep its center of mass over its wheels. This steering is usually supplied b ...

Segway PT
A Segway is a two-wheeled, self-balancing personal transporter device invented by Dean Kamen. The name is a registered trademark of Segway Inc. It was brought to market in 2001 as the Segway HT, and then subsequently as the Segway PT. ''HT'' is an initialism for "human transporter" and ''PT'' for "personal transporter." Ninebot, a Beijing-based transportation robotics startup rival, acquired Segway Inc. in April 2015, broadening the company to include other transportation devices. In June 2020, it was announced that it would no longer make the Segway PT. History Independent company The Segway PT, referred to during development and initial marketing as the Segway HT, was developed from the self-balancing iBOT wheelchair which was initially developed at University of Plymouth, in conjunction with BAE Systems and Sumitomo Precision Products.
