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 ...
A 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), [ 1 ] who conceived of the concept while working as an engineer with the Swedish company Mecanum AB, and patented it in the United ...
the BattleBot OMINOUS, shown here with a Kiwi Drive. A Kiwi drive is a holonomic drive system of three omni-directional wheels (such as omni wheels or Mecanum wheels), 120 degrees from each other, that enables movement in any direction using only three motors.
By combining two the motion of two-wheel the vehicle can move in the direction of the perpendicular wheel, or, by rotating all the wheels in the same direction, the vehicle can rotate in place. By using the resultant motion of the vector addition of the wheels a Killough platform is able to achieve omni-directional motion. [2]
A hemispherical omnidirectional gimbaled wheel (HOG wheel) is a drive system utilizing a hemisphere spinning continuously on its axis. When the hemisphere is horizontal, it is like a spinning top, and applies negligible torque to its contact point on the ground. When tipped on edge, however, it pulls like a traditional circular wheel.
In watches, the "drive" wheel is the one that winds up the spring, and the Geneva wheel with four or five spokes and one closed slot prevents overwinding (and also complete unwinding) of the spring. This so-called Geneva stop or "Geneva stop work" was the invention of 17th or 18th century watchmakers.
The channel officially launched on 6 October 2015. Living in Tampere, Finland, [6] Vuohensilta was inspired to create the Hydraulic Press Channel after discovering other YouTube channels committed to destroying objects, especially a channel called carsandwater, popular for videos of a man using a red-hot ball of nickel to melt various objects.

Path of wheels through a turn. The wheels are not connected, despite how it appears. If both the wheels are driven in the same direction and speed, the robot will go in a straight line. If both wheels are turned with equal speed in opposite directions, as is clear from the diagram shown, the robot will rotate about the central point of the axis.
