2. Tire rotation - Wikipedia

   en.wikipedia.org/wiki/Tire_rotation

   [citation needed] If the tires are unidirectional, the rotation can only be rotated front to back on the same side of the vehicle to preserve the rotational direction of the tires, unless they are remounted. More complex rotation patterns are required if the vehicle has a full-size spare tire that is part of the rotation, or if there are snow ...

3. Mecanum wheel - Wikipedia

   en.wikipedia.org/wiki/Mecanum_wheel

   a) Moving straight ahead, b) Moving sideways, c) Moving diagonally, d) Moving around a bend, e) Rotation, f) Rotation around the central point of one axle A Mecanum wheel is an omnidirectional wheel design for a land-based vehicle to move in any direction.

4. Skid (automobile) - Wikipedia

   en.wikipedia.org/wiki/Skid_(automobile)

   Once the vehicle is rotating sufficiently rapidly, its angular momentum of rotation can overcome the stabilizing influence of the tires (either braking or skidding), and the rotation will continue even if the wheels are centered or past the point that the vehicle is controlled. This can be caused by some tires locking up in braking while others ...

5. Killough platform - Wikipedia

   en.wikipedia.org/wiki/Killough_platform

   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]

6. Slip (vehicle dynamics) - Wikipedia

   en.wikipedia.org/wiki/Slip_(vehicle_dynamics)

   In (automotive) vehicle dynamics, slip is the relative motion between a tire and the road surface it is moving on. This slip can be generated either by the tire's rotational speed being greater or less than the free-rolling speed (usually described as percent slip), or by the tire's plane of rotation being at an angle to its direction of motion (referred to as slip angle).

7. Tire - Wikipedia

   en.wikipedia.org/wiki/Tire

   Rotation: Tires may exhibit irregular wear patterns once installed on a vehicle and partially worn. Front-wheel drive vehicles tend to wear the front tires at a greater rate compared to the rear tires. Tire rotation is moving the tires to different car positions, such as front-to-rear, in order to even out the wear, with the objective of ...

8. Caster angle - Wikipedia

   en.wikipedia.org/wiki/Caster_angle

   Caster causes a wheel to align with the direction of travel, and can be accomplished either by caster displacement or caster angle. Caster displacement moves the steering axis ahead of the axis of wheel rotation, as with the front wheels of a shopping cart. Caster angle moves the steering axis from vertical. [3]

9. Omni wheel - Wikipedia

   en.wikipedia.org/wiki/Omni_wheel

   The wheel was first patented in 1919 by J. Grabowiecki. US patent 1305535, J. Grabowiecki, "Vehicle wheel", issued 1919-06-03 . A variant of the wheel was patented by Josef F. Blumrich in 1972.
