Method for traversing surface with magnetic omni-wheel

1. A method for traversing a magnetically inducible surface using a multidirectional wheel, the method comprising:

providing a vehicle having the multidirectional wheel, wherein the wheel comprises:

a hub having hollow section;

at least one magnet within the hollow section of the hub;

the hub having a first axial direction of rotation and being made of a magnetically inducible material which is sized, shaped, and positioned to concentrate a flux of the at least one magnet through the hub and toward the magnetically inducible surface being traversed and thereby increase the attractive force between the wheel and the surface; and

a plurality of rollers disposed around an outer periphery of the hub, the rollers being mounted for rotation in a second axial direction that is at an angle to the first axial direction, at least a first roller in the plurality of rollers contacting a first portion of the magnetically inducible surface while a second roller in the plurality of rollers does not contact the magnetically inducible surface;

rotating the hub of the wheel along the first axial direction of rotation; and

continuing rotation of the hub of the wheel so as to cause the first roller disposed about the periphery of the hub to move out of contact with the first portion of the magnetically inducible surface and to cause the second roller disposed about the periphery of the hub in the plurality of rollers to contact a second portion of the magnetically inducible surface,

wherein at least one roller among the plurality of rollers is in contact with the magnetically inducible surface throughout rotation of the wheel, and

wherein the flux of the at least one magnet is concentrated toward portions of the surface being traversed adjacent to one or more of the plurality of rollers throughout rotation of the wheel.

2. The method as in claim 1 , wherein the vehicle further comprises a drive system, wherein the step of rotating the hub of the wheel uses the drive system.

3. The method as in clam 1 , further comprising protecting the magnet from the environment.

4. The method as in claim 1 , further comprising:

continuing rotation of the hub of the wheel so as to cause the second roller disposed about the periphery of the hub to move out of contact with the second portion of the magnetically inducible surface and to cause a third roller disposed about the periphery of the hub in the plurality of rollers to contact a third portion of the magnetically inducible surface,

wherein the third portion of the magnetically inducible surface is at an angle from the second portion of the magnetically inducible surface.

5. The method as in claim 4 , wherein the angle between the second portion and third portion of the magnetically inducible surface is orthogonal.

6. The method as in claim 1 , further comprising:

attaching at least one ferrous disk to the hub, wherein the ferrous disk includes an axial mounting hole;

connecting an axle to the axial mounting hole; and

driving the multidirectional wheel with the axle.

7. The method as in claim 6 , wherein the connecting step comprises a rotational connection between the axle and the at least one ferrous disk.

8. The method as in claim 1 , further comprising arranging at least one ferrous disk on the magnet mounted within the hub.

9. The method as in claim 8 , further comprising directing the magnet flux force away from the magnet and toward the ferrous disk.

10. The method as in claim 8 , further comprising:

disposing a non-magnetically inducible ring around the magnet, and

locking the rotation of the ferrous disk or hub.
