Omniwheel
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 (robotics), 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 wh ...

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] |

Ball Transfer Unit
Ball transfer units are omnidirectional load-bearing spherical balls mounted inside a restraining fixture (tool), fixture. They are identical in principle to a computer trackball (pointing device). Typically the design involves a single large ball supported by smaller ball bearings. They are commonly used in an inverted ball up position where objects are quickly moved across an array of units, known as a ball transfer table, a type of conveyor system. This permits manual transfer to and from machines and between different sections of another conveyor system. They are used in airports for luggage delivery, or in industry as part of manufacturing systems. Prior to the invention of the ball transfer unit, first patented by Autoset Production Ltd in 1958, these applications were solved by the use of inverted casters. However, casters recognise a trail, meaning that the wheels had to align before directional change could be achieved. Ball transfer units can also be used in a non-inver ...

Boeing C-17 Globemaster III
The McDonnell Douglas/Boeing C-17 Globemaster III is a large military transport aircraft that was developed for the United States Air Force (USAF) from the 1980s to the early 1990s by McDonnell Douglas. The C-17 carries forward the name of two previous piston-engined military cargo aircraft, the Douglas C-74 Globemaster and the Douglas C-124 Globemaster II. The C-17 is based upon the McDonnell Douglas YC-15, YC-15, a smaller prototype airlifter designed during the 1970s. It was designed to replace the Lockheed C-141 Starlifter, and also fulfill some of the duties of the Lockheed C-5 Galaxy. Compared to the YC-15, the redesigned airlifter differed in having swept wings, increased size, and more powerful engines. Development was protracted by a series of design issues, causing the company to incur a loss of nearly US$1.5 billion on the program's development phase. On 15 September 1991, roughly one year behind schedule, the first C-17 performed its maiden flight. The C-17 formally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cargo Aircraft
A cargo aircraft (also known as freight aircraft, freighter, airlifter or cargo jet) is a fixed-wing aircraft that is designed or converted for the carriage of air cargo, cargo rather than passenger aircraft, passengers. Such aircraft usually do not incorporate passenger amenities and generally feature one or more large doors for loading cargo. Freighters may be operated by civil passenger or cargo airlines, by private individuals or by the armed forces of individual countries. Aircraft designed for cargo flight usually have features that distinguish them from conventional passenger aircraft: a wide/tall fuselage cross-section, a high-wing to allow the cargo area to sit near the ground, numerous wheels to allow it to land at unprepared locations, and a high-mounted tail to allow cargo to be driven directly into and off the aircraft. By 2015, dedicated freighters represent 43% of the 700 billion ATK (available tonne-kilometer) capacity, while 57% is carried in Airliner#Baggage ...

Robotino
Robotino is a mobile robot system made by ''Festo Didactic'', and used for educational, training and research purposes. Operation Robotino is based on an omnidirectional drive assembly, which enables the system to roam freely. The robot is controlled by an industry-standard PC system, which is powerful enough to plan routes for fully autonomous driving. Via a WLAN-Link, Robotino can send all sensor readings to an external PC. In the other direction, control commands can be issued by the external PC. This way, control programs can run on the external PC or on Robotino directly. Mixed mode or shared control are also possible. For users with little prior robotics knowledge, Robotino can be readily programmed in its “native” programming environment RobotinoView II. More experienced programmers may find it useful that the robot can also be programmed in C, C++, Java, .NET, Matlab, Simulink, Labview and Microsoft Robotics Developer Studio. Hardware The omnidirectional drive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robot Soccer
A robot is a machine—especially one Computer program, programmable by a computer—capable of carrying out a complex series of actions automatically. A robot can be guided by an external control device, or the robot control, control may be embedded within. Robots may be constructed to evoke Humanoid robot, human form, but most robots are task-performing machines, designed with an emphasis on stark functionality, rather than expressive aesthetics. Robots can be autonomous robot, autonomous or semi-autonomous and range from humanoids such as Honda's ''Advanced Step in Innovative Mobility'' (ASIMO) and TOSY's ''TOSY Ping Pong Playing Robot'' (TOPIO) to industrial robots, robot-assisted surgery, medical operating robots, patient assist robots, dog therapy robots, collectively programmed Swarm robotics, ''swarm'' robots, UAV drones such as General Atomics MQ-1 Predator, and even microscopic Nanorobotics, nano robots.

London Free Press
''The London Free Press'' is a daily newspaper based in London, Ontario, London, Ontario, Canada. It has the largest circulation of any newspaper in Southwestern Ontario. History ''The London Free Press'' began as the ''Canadian Free Press'', founded by William Sutherland. It first began printing as a weekly newspaper on January 2, 1849. In 1852, it was purchased for $500 by Josiah Blackburn (and Stephen Blackburn), who renamed it ''The London Free Press and Daily Western Advertiser''. In 1855 Blackburn turned the weekly newspaper into a daily. From 1863 to 1936 ''The London Free Press'' competed for readership with the ''London Advertiser'', which was a daily evening newspaper. The ''Free Press'' has usually been a morning paper, but for many years, it also published an evening paper. Both morning and evening editions were published from the 1950s through to 1981, when the evening edition was permanently retired. The Blackburn family was also involved in other forms of media ...

The Spaceships Of Ezekiel
''The Spaceships of Ezekiel'' (1974) is a book by Josef F. Blumrich (March 17, 1913 – February 10, 2002) about a spaceship that was supposedly observed by the prophet Ezekiel, written while the author was chief of NASA's systems layout branch of the program development office at the Marshall Space Flight Center. It was originally published in German by Econ Verlag GmbH under the title ''Da tat sich der Himmel auf'' (March 1973). History After ufologists such as Erich von Däniken had pointed to the possibility of interpreting Ezekiel's Merkabah vision as a report of an extraterrestrial spacecraft, Blumrich decided to disprove the hypothesis. However, a thorough examination convinced him that Ezekiel had, in fact, seen a spaceship. He then made detailed drawings of the alien craft. He decided the technology of the builders must have been somewhat higher than mankind's at the present, and added he had seldom felt as delighted, satisfied, and fascinated by being proven wrong. ...
