Killough Platform
A Killough platform is a three-wheel drive system that uses traditional wheels to achieve omni-directional movement without the use of omni-directional wheels (such as omni wheels/ Mecanum wheels). Designed by Stephen Killough, after which the platform is named, with help from Francois Pin, wanted to achieve omni-directional movement without using the complicated six motor arrangement required to achieve a controllable three caster A caster (or castor) is an undriven wheel that is designed to be attached to the bottom of a larger object (the "vehicle") to enable that object to be moved.

This led to the Killough system: With Francois Pin, who he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Killough Platform - Range Of Movement
Killough ( ; ) is a village and townland in County Down, Northern Ireland. It lies on the Irish Sea shore near Ardglass, five miles southeast of Downpatrick. It is a conservation area notable for its sycamore-lined main street. In the 2001 Census it had a population of 845 people.http://www.ninis.nisra.gov.uk/ NI Neighbourhood Information Service History The townland of Killough appears in the Down Survey as ''Kiltaghlins.'' The owner in 1641 was given as Thomas Cromwell Viscount of Lecale, a direct descendent of Thomas Cromwell chief minister to Henry VIII. The harbour was built in the 18th century by the Wards of Castle Ward house, just outside Strangford. Michael Ward had the straight road from Castle Ward to Killough built in 1740. Ward called the village Port St Anne but that name did not stick. The name ''St Anne's Port'' was also used. After the outbreak of war between Great Britain and France in 1793 the growing of cereals increased in Lecale and Killough, as one of t ...

Omni Wheel
Omni wheels or poly wheels, similar to Mecanum wheels, are wheels with small discs (called rollers) around the circumference which are perpendicular to the turning direction. The effect is that the wheel can be driven with full force, but will also slide laterally with great ease. These wheels are often employed in holonomic drive systems. A platform employing three omni wheels in a triangular configuration is generally called Kiwi Drive. The Killough platform is similar; so named after Stephen Killough's work with omnidirectional platforms at Oak Ridge National Laboratory. Killough's 1994 design used pairs of wheels mounted in cages at right angles to each other and thereby achieved holonomic movement without using true omni wheels. They are often used in intelligent robot research for small autonomous robots. In projects such as VEX Robotics, Robocup and FIRST Robotics, many robots use these wheels to have the ability to move in all directions. Omni wheels are also somet ...

Mecanum Wheel
The mecanum wheel is an omnidirectional wheel design for a land-based vehicle to move in any direction. It is sometimes called the Swedish wheel or Ilon wheel after its inventor, Bengt Erland Ilon (1923–2008), who conceived of the concept while working as an engineer with the Swedish company Mecanum AB, and patented it in the United States on November 13, 1972. Design The mecanum wheel is a form of tireless wheel, with a series of rubberized external rollers obliquely attached to the whole circumference of its rim. These rollers typically each have an axis of rotation at 45° to the wheel plane and at 45° to the axle line. Each Mecanum wheel is an independent non-steering drive wheel with its own powertrain, and when spinning generates a propelling force perpendicular to the roller axle, which can be vectored into a longitudinal and a transverse component in relation to the vehicle. The typical Mecanum design is the four-wheel configuration as demonstrated by one of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caster
A caster (or castor) is an undriven wheel that is designed to be attached to the bottom of a larger object (the "vehicle") to enable that object to be moved. Casters are used in numerous applications, including shopping carts, office chairs, toy wagons, hospital beds, and material handling equipment. High capacity, heavy duty casters are used in many industrial applications, such as platform trucks, carts, assemblies, and tow lines in plants. Types Casters may be fixed to roll along a straight line path, or mounted on a pivot or pintle such that the wheel will automatically align itself to the direction of travel. Rigid casters A basic, rigid caster consists of a wheel mounted to a stationary fork. The orientation of the fork, which is fixed relative to the vehicle, is determined when the caster is mounted to the vehicle. An example of this is the wheels found at the rear of a shopping cart in North America. Rigid casters tend to restrict vehicle motion so that the vehicle t ...
