1 A caster is a wheel mounted to a fork, with an optional, additional offset steering joint. 2  An omni-directional wheel (Mecanum wheel, Omni wheel, or Swedish wheel) is made of a large central hub with many additional smaller wheels mounted along the perimeter such that their axes are perpendicular to the central wheel.
The caster is the amount by which a steered wheel trails behind the vertical axis about which it is steered. Positive caster projects the load of the vehicle to a point on the road ahead of the tire contact. If the caster angle is too large, it will cause heavy steering and the driver will quickly get tired. Negative caster helps to center the steering wheel after a turn, and makes the front tires straighten quicker.
