     TECHNICAL FIELD 
     Generally, the present disclosure relates to transportation. More particularly, the present disclosure relates to motorized transportation. 
     BACKGROUND 
     In the present disclosure, where a document, an act and/or an item of knowledge is referred to and/or discussed, then such reference and/or discussion is not an admission that the document, the act and/or the item of knowledge and/or any combination thereof was at the priority date, publicly available, known to the public, part of common general knowledge and/or otherwise constitutes prior art under the applicable statutory provisions; and/or is known to be relevant to an attempt to solve any problem with which the present disclosure is concerned with. Further, nothing is disclaimed. 
     A rider can ride a lateral sliding roller board, such as a freeboard, on a city street, a sidewalk, a playground, a sports complex, or some other surface to simulate unique movements of snowboarding. However, such board is typically configured for riding down an incline, a mountain, or a hill since a lateral sliding movement unique to such board usually cannot be sustained while riding on a flat terrain or up an inclined terrain. If the rider does not have access to the incline, the hill, or the mountain, then the board typically cannot operate as designed. Resultantly, such state of being has generally contributed to a limited adoption of such board, as public access to the incline, the hill, or the mountain is not widespread. Although a powered skateboard allows the rider to ride without human power, such as in a “carving” style using a set of skateboard trucks, the powered skateboard is typically unable to provide the lateral sliding movement of the snowboard or the lateral sliding roller board.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
     The present disclosure is now described more fully with reference to the accompanying drawings, in which example embodiments of the present disclosure are shown. The present disclosure may, however, be embodied in many different forms and should not be construed as necessarily being limited to the example embodiments disclosed herein. Rather, these example embodiments are provided so that the present disclosure is thorough and complete, and fully conveys the concepts of the present disclosure to those skilled in the relevant art. 
     Features described with respect to certain example embodiments may be combined and sub-combined in and/or with various other example embodiments. Also, different aspects and/or elements of example embodiments, as disclosed herein, may be combined and sub-combined in a similar manner as well. Further, some example embodiments, whether individually and/or collectively, may be components of a larger system, wherein other procedures may take precedence over and/or otherwise modify their application. Additionally, a number of steps may be required before, after, and/or concurrently with example embodiments, as disclosed herein. Note that any and/or all methods and/or processes, at least as disclosed herein, can be at least partially performed via at least one entity in any manner. 
     The terminology used herein can imply direct or indirect, full or partial, temporary or permanent, action or inaction. For example, when an element is referred to as being “on,” “connected” or “coupled” to another element, then the element can be directly on, connected or coupled to the other element and/or intervening elements can be present, including indirect and/or direct variants. In contrast, when an element is referred to as being “directly connected” or “directly coupled” to another element, there are no intervening elements present. 
     Although the terms first, second, etc. can be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not necessarily be limited by such terms. These terms are used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer, or section discussed below could be termed a second element, component, region, layer, or section without departing from the teachings of the present disclosure. 
     The terminology used herein is for describing particular example embodiments and is not intended to be necessarily limiting of the present disclosure. As used herein, the singular forms “a,” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises,” “includes” and/or “comprising,” “including” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence and/or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. 
     As used herein, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless specified otherwise, or clear from context, “X employs A or B” is intended to mean any of the natural inclusive permutations. That is, if X employs A; X employs B; or X employs both A and B, then “X employs A or B” is satisfied under any of the foregoing instances. 
     Example embodiments of the present disclosure are described herein with reference to illustrations of idealized embodiments (and intermediate structures) of the present disclosure. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, the example embodiments of the present disclosure should not be construed as necessarily limited to the particular shapes of regions illustrated herein, but are to include deviations in shapes that result, for example, from manufacturing. 
     Any and/or all elements, as disclosed herein, can be formed from a same, structurally continuous piece, such as being unitary, and/or be separately manufactured and/or connected, such as being an assembly and/or modules. Any and/or all elements, as disclosed herein, can be manufactured via any manufacturing processes, whether additive manufacturing, subtractive manufacturing, and/or other any other types of manufacturing. For example, some manufacturing processes include three dimensional (30) printing, laser cutting, computer numerical control routing, milling, pressing, stamping, vacuum forming, hydroforming, injection molding, lithography, and so forth. 
     Any and/or all elements, as disclosed herein, can be and/or include, whether partially and/or fully, a solid, including a metal, a mineral, an amorphous material, a ceramic, a glass ceramic, an organic solid, such as wood and/or a polymer, such as rubber, a composite material, a semiconductor, a nanomaterial, a biomaterial and/or any combinations thereof. Any and/or all elements, as disclosed herein, can be and/or include, whether partially and/or fully, a coating, including an informational coating, such as ink, an adhesive coating, a melt-adhesive coating, such as vacuum seal and/or heat seal, a release coating, such as tape liner, a low surface energy coating, an optical coating, such as for tint, color, hue, saturation, tone, shade, transparency, translucency, opaqueness, luminescence, reflection, phosphorescence, anti-reflection and/or holography, a photo-sensitive coating, an electronic and/or thermal property coating, such as for passivity, insulation, resistance or conduction, a magnetic coating, a water-resistant and/or waterproof coating, a scent coating and/or any combinations thereof. Any and/or all elements, as disclosed herein, can be rigid, flexible, and/or any other combinations thereof. Any and/or all elements, as disclosed herein, can be identical and/or different from each other in material, shape, size, color and/or any measurable dimension, such as length, width, height, depth, area, orientation, perimeter, volume, breadth, density, temperature, resistance, and so forth. 
     Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and should not be interpreted in an idealized and/or overly formal sense unless expressly so defined herein. 
     Furthermore, relative terms such as “below,” “lower,” “above,” and “upper” can be used herein to describe one element&#39;s relationship to another element as illustrated in the accompanying drawings. Such relative terms are intended to encompass different orientations of illustrated technologies in addition to the orientation depicted in the accompanying drawings. For example, if a device in the accompanying drawings were turned over, then the elements described as being on the “lower” side of other elements would then be oriented on “upper” sides of the other elements. Similarly, if the device in one of the figures were turned over, elements described as “below” or “beneath” other elements would then be oriented “above” the other elements. Therefore, the example terms “below” and “lower” can encompass both an orientation of above and below. 
     As used herein, the term “about” and/or “substantially” refers to a +/−10% variation from the nominal value/term. Such variation is always included in any given value/term provided herein, whether or not such variation is specifically referred thereto. 
     U.S. Pat. No. 5,975,546 is herein fully incorporated by reference for all purposes. U.S. Pat. No. 4,250,658 is herein fully incorporated by reference for all purposes. If any disclosures are incorporated herein by reference and such disclosures conflict in part and/or in whole with the present disclosure, then to the extent of conflict, and/or broader disclosure, and/or broader definition of terms, the present disclosure controls. If such disclosures conflict in part and/or in whole with one another, then to the extent of conflict, the later-dated disclosure controls. 
       FIG.  1    shows a perspective view of an example embodiment of a powered lateral sliding roller board according to the present disclosure. A powered lateral sliding roller board  100  comprises a platform  102  comprises a center portion  104 , a front portion  106 , and a rear portion  108 . The platform  102  comprises a pair of side portions  110  extending longitudinally along the platform  102  through the front portion  106 , the center portion  104 , and the rear portion  108 . The platform  102  comprises at least one of plastic, metal, rubber, wood, and glass, or any combinations thereof. In some embodiments, the front portion  106  is sufficiently different in at least one of size and shape from the rear portion  108  such that a rider can easily visually distinguish therebetween, but in other embodiments, the front portion  106  is not sufficiently different in at least one of size and shape from the rear portion  108  such that a rider can easily visually distinguish therebetween. Further, in some embodiments, the side portions  110  are symmetrical to each other, but in other embodiments, the side portions  110  are asymmetrical to each other. Also, in some embodiments, the platform  102  is at least one of wider and longer than a conventional skateboard platform, where the conventional skateboard platform is at least from about 7 inches to about 9 inches wide and from about 31 inches to about 34 inches long. For example, the platform  102  can be about 10 inches wide and about 40 inches long. 
     The board  100  further comprises a pair of foot hooks  112 , positioned on opposing sides of the platform  102 , such as the front portion  106  and the rear portion  108 . Each of the foot hooks  112  comprises a foot hook plate  114 , which can be assembled with and/or be unitary to the foot hook  112 . At least one of the foot hooks  112  comprises at least one of plastic, metal, rubber, wood, and glass, or any combinations thereof. At least one of the foot hooks  112  can be unitary and/or an assembly. Each of the foot hooks  112  comprises a pair of opposing rows defined via a plurality of openings  146 , at least one of which can be circular, square, triangular, or some other shape. Although the opposing rows are rectilinear in extension, the opposing rows can extend in other ways, such as arcuate, wavy, or zigzag. The openings  146  can be directly opposing each other or be offset from each other, such as via one position. Each of the foot hooks  112  comprises a pair of fasteners  144 , such as a screw or a bolt. At least one of the fasteners  144  comprises at least one of plastic, metal, rubber, wood, and glass, or any combinations thereof. Each of the fasteners  144  corresponds to each of the rows defined via the openings  146 . For each of the rows defined via the openings  146 , each of the fasteners  144  extends through one of the openings  146 . Such extension provides for foot hook  112  adjustment based on rider comfort, such as for accommodating various rider foot sizes, whether as measured in length, width, and/or height. Accordingly, the fasteners  144  can be fastened and unfastened selectively. 
     At least one of the foot hook plates  114  can be unitary and/or an assembly. At least one of the foot hook plates  114  comprises at least one of plastic, metal, rubber, wood, and glass, or any combinations thereof. Each of the foot hook plates  114  defines an opening  116  therein. Each of the foot hooks  112  is secured to the platform  102  via a fastener  118  extending through the opening  116 . Note that the opening  116  in the foot hook  112  secured in the rear portion  108  is circular and the opening  116  in the foot hook  112  secured in the front portion  106  is arcuate. Resultantly, the foot hook  112  secured in the rear portion  108  is positionally fixed, as the opening  116  precludes any movement of the foot hook  112  secured in the rear portion  108 . In contrast, the foot hook  112  secured in the front portion  106  is laterally rotatable, as the opening  116  enables a lateral movement of the foot hook  112  secured in the front portion  106 . Such rotation provides an ability change an angle of a rider&#39;s foot. For example, the angle can range from about 0 degrees to about −45 degrees and about 0 degrees to about 45 degrees relative to a roughly perpendicular plane to an imaginary longitudinal center line  120  on of the platform  104 . For another example, such rotation can be at least about 5 degrees from a central alignment position along the line  120  toward at least one of the side portions  110 . Note that other ways of securing the foot hook  112  to the platform  102  can be used, such as nailing, adhering, mating, interlocking, bolting, or clamping. Also, note that both of the foot hooks  112  can be fixed in position, such as the foot hook  112  secured in the rear portion  108 , or both of the hooks  112  can be laterally rotatable, such as the foot hook  112  secured in the front portion  106 . In some embodiments, the board  100  comprises at most one foot hook  112 , whether in a fixed position configuration or a laterally rotating configuration. In other embodiments, at least one of the foot hooks  112  is at least one of U-shaped, C-shaped, E-shaped, T-shaped, O-shaped, P-shaped, J-shaped, D-shaped, H-shaped, L-shaped, or V-shaped. Note that such foot hook  112  can be coupled to the platform  102  in any manner, such as via fastening, adhering, mating, or interlocking, at any point of the foot hook  112 , whether upright, sideways, or inverted, for foot insertion thereinto such that a rider&#39;s foot is relatively secured to the platform  102 . In some embodiments, the board  100  lacks at least one of the foot hooks  112 . In some embodiments, the board  100  lacks both of the foot hooks  112  as the rider does not need to use the foot hooks  112  to ride the board  100  as at least one of the foot hooks  112  is operably coupled to the platform  102  to provide additional control and support. 
     An energy source  122  provides energy to a motor such that the motor is able to propel the board  100 . The source  122  comprises at least one of plastic, metal, rubber, wood, and glass, or any combinations thereof. The source  122  may be an engine, a motor, a battery, a fuel tank, a photovoltaic cell, a capacitor, or another energy source. For example, the fuel tank can contain gasoline which is combusted in the engine such that the engine powers the motor to propel the board  100 . The source  122  can be rechargeable whether in a wireless manner, such as via induction, and/or a wired manner, such as via a line. The source  122  is secured to the platform  102 , between the foot hooks  112  on an upper side of the platform  102 . The source  122  is secured to the platform  102  via fastening, but in other embodiments, the source  122  is secured to the platform  102  via nailing, adhering, mating, interlocking, bolting, clamping, or any combinations thereof. In yet other embodiments, the source  122  is secured to the platform  102 , between the foot hooks  112  on a lower side of the platform  102 . In still other embodiments, the source  122  is not between the foot hooks  122 , such as in the front portion  106  and/or the rear portion  108 . Note that more than one source  122  can be used in any manner, whether powering one or more motors in any manner, whether synchronously and/or asynchronously, independently and/or dependently, in one manner and/or in different manners, and/or in any type of correspondence, such as one-to-one, many-to-many, one-to-many, and/or many-to-one. 
     The board  100  further comprises a front truck  124  comprising a pair of frontal wheels  126  and a rear truck  128  comprising a pair of rear wheels  130 . The front truck  124  is secured to the platform  102  in the front portion  106 , such as via fastening, adhering, mating, or interlocking. The rear truck  128  is secured to the platform  102  in the rear portion  108 , such as via fastening, adhering, mating, or interlocking. At least one of the front truck  124 , the rear truck  128 , at least one of the frontal wheels  126 , and at least one of the rear wheels  130  comprises at least one of plastic, metal, rubber, wood, and glass, or any combinations thereof. 
     In one mode of operation, a rider R stands on the platform  102  such that the rider&#39;s R feet are under the foot hooks  112  in a stance similar to that used for snowboarding, surfing, or skateboarding. The rider R stands sideways with a back foot BF roughly perpendicular or at a varying angle to the line  120  and a front foot FF being roughly perpendicular or at a varying angle to the line. This stance allows the rider R to easily shift the rider&#39;s R weight onto the rider&#39;s R toes or onto the rider&#39;s R heels. However, note that the rider&#39;s R feet can be at any angle, as measured from the line  120 , as many riders have their own ‘stance’ preferences with known angles. For example, some riders ride at a 30/15 orientation where 30 degrees in the front foot FF and 15 degrees on the back foot BF, as measured from the line  120 . The rider R can also move freely about the upper side of the platform  102 , assuming different stances for different maneuvers. As with a conventional skateboard, the front portion  106  and the rear portion  108  angle upwards from the platform  102 . Via transferring the rider&#39;s R weight to the front portion  106  or the rear portion  108 , the rider R can perform numerous tricks and maneuvers where part or all of the powered lateral sliding roller board  100  becomes elevated from a ground surface on which at least one of the wheels  126  and the wheels  130  roll. Note that the board  100  can ride forwards, backwards, or laterally. 
       FIG.  2    shows an underside view of an example embodiment of a powered lateral sliding roller board according to the present disclosure. Some elements of this figure are described above. Thus, same reference characters identify identical and/or like components described above and any repetitive detailed description thereof will hereinafter be omitted or simplified in order to avoid complication. 
     The truck  124  comprises a fixed wheel assembly  132  and the truck  128  comprises a fixed wheel assembly  134 , both of which are positioned along the line  120  opposing each other. In other embodiments, the assembly  132  and the assembly  134  are offset from each other. In some embodiments, at least one of the assembly  132  and the assembly  134  is powered via a motor, at least as described herein, whether independently from each other and/or dependent on each other, whether in a synchronized manner and/or a non-synchronized manner. In some embodiments, at least one of the assembly  132  and the assembly  134  is not fixed, such as rotating, for instance within about 50 degrees to each side of the platform  102  from the line  120 . Note that each of the wheel assembly  132  and the assembly  134  can have two wheels, less than two wheels, and/or more than two wheels, whether per assembly and/or per side. 
     The board  100  further comprises a plurality of motorized roller assemblies  136 ,  138  secured to the platform  102 , such as via fastening, adhering, mating, or interlocking, between the assembly  132  and the assembly  134 . However, in other embodiments, at least one of the roller assemblies  136 ,  138  is not between the assembly  132  and the assembly  134 , such as between a frontal tip of the platform  102  and the assembly  132  or between a rear tip of the platform  102  and the assembly  134  or no roller assemblies  136 ,  138  are between the assembly  132  and the assembly  134 . The roller assemblies  136 ,  138  are aligned with each other and along the line  120 . However, in other embodiments, the roller assemblies  136 ,  138  are not aligned with each other and/or along the line  120 , such only one of the roller assemblies  136 ,  138  is aligned along the line  120  or the roller assemblies  136 ,  138  are offset from each other while not being aligned to the line  120 . Each of the roller assemblies  136 ,  138  is configured to rotate 360 degrees with respect to the platform  102 . Each of the roller assemblies  136 ,  138  is configured to be elastically biased, such as via a spring, for instance a coiled spring, while constantly contacting the ground surface and self-aligning with a direction of force applied onto the platform  102  during riding. More particularly, each of the roller assemblies  136 ,  138  is elastically biased, such as via a spring, to self-align along the line  120 , pointed either forward towards the front portion  106  or backward towards the rear portion  108 , without interfering with motor-powered operation of each of the roller assemblies  136 ,  138 . Such bias simulates a natural tracking tendency of a ski and/or a snowboard, while enhancing rider control. Also, note that the bias is sufficiently strong to add rider control, yet configured such that the rider is substantially precluded from rotating the platform  102  into sideways riding. In some embodiments, the bias manifests via a roller being attached to a frame, while rotating about a horizontal axis of rotation, with a cam follower being pivotally coupled to the frame and including a torsion spring. The cam follower comprises a bearing. The cam follower is forced by an elastic member, such as a spring, to be positioned against a cam which is fixed relative to the platform  102 , which causes the frame to rotate to a position of least force between the cam and the cam follower. Accordingly, a bias profile is established via adjusting at least one of a cam shape and a spring force on the cam follower. One example of the cam is a pair of M-shaped curves symmetrically coupled to each other at their ends at a pair of apexes. In some embodiments, only one of the roller assemblies  136 ,  138  is motor powered. In some embodiments, at least one of the roller assemblies  136 ,  138  comprises the source  122 . Note that although the roller assemblies  136 ,  138  are described in a context of the board  100 , at least one of the roller assemblies  136 ,  138  can be applied to other environments, functions and/or structures, at least in a manner as described herein, such as in a luggage item, a suitcase, a travel bag, a roller skate, an industrial equipment device, a material handling equipment item, a furniture item, a toy, a cart, a robot, a wheelchair, a medical device, a stretcher, a bed, a gurney, a chair, a table, a shopping cart, a platform truck, a tow line in a plant, a pallet, a skid, a video game console, a computer, and/or a vehicle, whether land, aerial, and/or marine, whether manned and/or unmanned, whether for recreation, construction, military, industrial, law enforcement, or medical purposes. 
     The fixed wheel assemblies  132 ,  134  provide a different functional characteristic and a different effect on maneuvering than do the roller assemblies  136 ,  138 . Resultantly, arranging the fixed wheel assemblies  132 ,  134  with the roller assemblies  136 ,  138  as shown simulates snowboarding relatively effectively, while travelling under power across flat terrain, down inclined terrain, or up inclined terrain. At least one of the fixed wheel assemblies  132 ,  134  comprises at least one of plastic, metal, rubber, wood, and glass, or any combinations thereof. At least one of the roller assemblies  136 ,  138  comprises at least one of plastic, metal, rubber, wood, and glass, or any combinations thereof. 
     Note that the roller assemblies  136 ,  138  can be identical to and/or different from each other in any way, at least as described herein, whether structurally and/or functionally. For example, one of the roller assemblies  136 ,  138  can be biased and the other one of the roller assemblies  136 ,  138  can be non-biased, although both can be biased or non-biased. Also, for example, one of the roller assemblies  136 ,  138  can be powered in one manner and the other one of the roller assemblies  136 ,  138  can be powered in another manner, although both can be both can be powered in one manner. Additionally, for example, one of the roller assemblies  136 ,  138  can comprise one type of motor and the other one of the roller assemblies  136 ,  138  can comprise another type of motor, although both can comprise one type of motor. Moreover, for example, one of the roller assemblies  136 ,  138  can comprise one type of driving mechanism and the other one of the roller assemblies  136 ,  138  can comprise another type of driving mechanism, although both can comprise one type of driving mechanism. 
     Note that the fixed wheel assemblies  132 ,  134  are sufficiently spaced apart such that the board  100  is relatively stable to ride on. Resultantly, as a distance between the fixed wheels assemblies  132 ,  134  increases, the board  100  rides in a more stable manner. For example, a distance from a transverse axis  140  of the fixed wheel assembly  132  to a transverse axis  142  of the fixed wheel assembly  134  is longer than the conventional skateboard, such as by about 33% in some embodiments. Also, note that the fixed wheel assemblies  132 ,  134  and the roller assemblies  136 ,  138  are sufficiently close such that the fixed wheel assemblies  132 ,  134  and the roller assemblies  136 ,  138  avoid mechanical interference with each other. Similarly, note that as a distance between the roller assemblies  136 ,  138  grows, the board  100  rides in a more stable manner. 
       FIG.  3    shows a frontal view of an example embodiment of a powered lateral sliding roller board in a first state according to the present disclosure. Some elements of this figure are described above. Thus, same reference characters identify identical and/or like components described above and any repetitive detailed description thereof will hereinafter be omitted or simplified in order to avoid complication. 
     The roller assembly  136  comprises a roller  140 , which is motorized, as powered via the energy source  122 . The board  100  is in a first riding state where the board  100  rides on the left wheel  126  and the roller  140 , with the right wheel  126  being raised above the ground surface at a height differential of Δh. The first state can be initiated via the rider R leaning toward the left side  110 . The left wheel  126  is assisted in rolling via the roller  140 , as powered via the motor. Note that similar state of being exists with respect to the rear truck  128  and the rear roller assembly  138 . Also, note that via the rider R shifting weight from one side to another, the rider R can use the powered lateral sliding roller board  100  to carve under power without entering into a sliding mode. 
       FIG.  4    shows a frontal view of an example embodiment of a powered lateral sliding roller board in a second state according to the present disclosure. Some elements of this figure are described above. Thus, same reference characters identify identical and/or like components described above and any repetitive detailed description thereof will hereinafter be omitted or simplified in order to avoid complication. 
     The board  100  is in a second riding state where the board  100  rides on the roller  140 , with the left wheel  126  and the right wheel  126  being raised above the ground surface. The second state can be initiated via the rider R centering and/or sufficiently balancing on the platform  102  without overly leaning toward the left side  110  or the right side  110 . The roller  140 , whether motor powered or not, enables such riding of the board  100 . Note that similar state of being exists with respect to the rear truck  128  and the rear roller assembly  138 . Also, note that the rider&#39;s R weight rests solely on the roller assemblies  136 ,  138  and the board  100  can ride, whether motor powered or not, in any direction according to an omnidirectional rotation of the roller assemblies  136 ,  138 , such as 360 degrees. However, note that such type of riding and/or omnidirectional rotation can be limited via elastic biasing, such as via a spring, of the roller assemblies  136 ,  138 . Also note that entering the omnidirectional riding mode does not necessarily depend on the wheels  126  being raised from the ground surface. One factor is how much force is being applied onto the wheels  126 . For example, if the rider R is generally centered over the platform  102 , then the rider&#39;s R weight substantially rests on the pivoting rollers  140 , which decreases friction between the wheels  126  and the ground surface to a level where the board  100  can slide laterally. 
       FIG.  5    shows a frontal view of an example embodiment of a powered lateral sliding roller board in a third state according to the present disclosure. Some elements of this figure are described above. Thus, same reference characters identify identical and/or like components described above and any repetitive detailed description thereof will hereinafter be omitted or simplified in order to avoid complication. 
     The board  100  is in a third riding state where the board  100  rides on the right wheel  126  and the roller  140 , with the left wheel  126  being raised above the ground surface at the height differential of Δh. The third state can be initiated via the rider R leaning toward the right side  110 . The right wheel  126  is assisted in rolling via the roller  140 , as powered via the motor. Note that similar state of being exists with respect to the rear truck  128  and the rear roller assembly  138 . Also, note that via the rider R shifting weight from one side to another, the rider R can use the powered lateral sliding roller board  100  to carve under power without entering into a sliding mode. 
     As seen at least from above,  FIGS.  3 - 5    show how the rider R can implement variable speed control while riding under motor power. The rider can also use at least one of the foot hooks  112  to secure the rider&#39;s R feet in place to gain additional control of the board  100 .

For example, the drive shafts  160  extend in opposing directions from the motor  158 . In some embodiments, the motor  158  is configured to provide 5,000 rotations per minute (RPM). In some embodiments, the motor  158  is a 2,000-watt brushless electric motor. In some embodiments, the motor  158  is able to propel the board  100  between about 20 miles per hour (MPH) and about 30 MPH. Note that at least one of the mounts  148  is operably coupled to the roller  156  and therefore the at least one of the mounts  148  rotates with the roller  156 . However, in other embodiments, at least one of the mounts  148  comprise the roller  156  or the motor  158 . In some embodiments, the board  100  comprises a plurality of sources  122 , where the sources  122  power the motors  158  in a one-to-one correspondence, many-to-one correspondence, one-to-many correspondence, and/or many-to-many correspondence. In some embodiments, the motors  158  are of one type, such as the motors  158  are electric, while in other embodiments, the motors  158  are of different types, such as one is brushed and one is brushless. 
     Each of the roller assemblies  136 ,  138  comprises a motor pulley wheel  162 , a roller pulley wheel  164 , and a timing belt  166  mounted under tension over the wheel  162  and the wheel  164  to synchronize rotation therebetween, as driven via the motor  158 . The wheel  162  is mounted onto the shaft  160 , with the mount  148 B interposed therebetween. The wheel  162  comprises at least one of plastic, metal, rubber, wood, and glass, or any combinations thereof.

The fastener  170  can be a bolt or a screw. In some embodiments, at least one of the assemblies  136 ,  138  comprises a nut  172  fastened onto the fastener  170  such that the mount  1486  is interposed therebetween and the wheel  168  is more secured thereby. The wheel  168  adds tension to the timing belt  166  between the wheel  162  and the wheel  164 , thus precluding substantial slippage of the belt  166  while riding under power of the motor  158 . Although the wheel  168  is above the belt  166 , in other embodiments, the wheel  168  is below the belt  166 , such as shown in  FIG.  2   .

In other embodiments, the ring  176  is stationary and the brush  178  rotates. 
       FIG.  10    shows a pair of top views and a front side view of an example embodiment of a powered lateral sliding roller board and a segment of the powered lateral sliding roller board respectively according to the present disclosure. Some elements of these figures are described above. Thus, same reference characters identify identical and/or like components described above and any repetitive detailed description thereof will hereinafter be omitted or simplified in order to avoid complication. 
     The platform  102  is defined via a first segment  102 A and a second segment  102 B when the segments  102 A,  102 B are assembled with each other, such as manually. Accordingly, the platform  102  is configured for disassembly along a width of the platform  102 , which is substantially perpendicular to the line  120 . In other embodiments, the platform  102  configured for disassembly along a length of the platform  102 , which is substantially parallel to the line  120 . In yet other embodiments, the platform  102  is configured for disassembly along a slant of the platform  102 , which is substantially diagonal to the line  120 . Note that disassembly along at least one of a wavy line, an arcuate line, and a zigzag line is possible as well. The segments  102 A,  102 B can be symmetrical and/or asymmetrical to each other. 
     Each of the segments  102 A,  102 B comprises a male connector  180  and a female connector  182  configured for interlocking and/or mating with the other female connector  182  and the other male connector  180 , respectively. The male connector  180  can be unitary to and/or assembled with at least one of the segments  102 A,  102 B. In other embodiments, the segments  102 A,  102 B are assembled via a single male connector  180  and a single female connector  182 . 
     Each of the segments  102 A,  102 B comprises at least one electrical interface connector  184  in contact with at least one wire running along the respective segment  102 A,  102 B. When the segments  102 A,  102 B are assembled with each other, such as via the male connector  180  and the female connector  182 , the respective connectors  184  electrically interface with each other to create a path, such as a circuit, for conduction of at least one of electrical circuit and data. In other embodiments, at least one pair of the male connector  180  and the female connector  182  comprise a pair of corresponding electrical contacts, such as a pair of leads. For example, an electrical circuit is created along the platform  102 , such as via a wire, whether internal to the platform  102  and/or external to the platform  102 , when electrical current can flow from one of the segments  102 A,  1026  to the other across such electrical contacts as such contacts are in electrical contact with each other based on the segment  102 A being assembled with the segment  1026  to form the platform  102 . 
       FIG.  11    shows a flowchart of an example embodiment of a computer-implemented process for traction control software employed on a powered lateral sliding roller board according to the present disclosure. Some elements of these figures are described above. Thus, same reference characters identify identical and/or like components described above and any repetitive detailed description thereof will hereinafter be omitted or simplified in order to avoid complication. 
     The board  100  comprises a hardware processor, such as a single core chip or a multi-core chip, and a memory, such as non-volatile memory, for instance flash memory, operably coupled to the processor. The memory storing a set of instructions for execution by the processor, whether serially and/or in parallel. For example, the processor and the memory can be installed in a controller unit coupled to the platform  102 , such as via mating, adhering, fastening, or interlocking. The controller unit comprises a transceiver operably coupled to the processor and an antenna operably coupled to the transceiver for wireless communication with a remote control, such as via a short-range wireless communication protocol, such as infrared based and/or radiofrequency (RF) based. In some embodiments, the controller unit includes a receiver alternative to the transceiver. The set of instructions is instructive to assist in board traction control in order to optimize a riding speed of at least one of the roller assemblies  136 ,  138  relative to a specific rider input, such as a setting. Some examples of such setting comprise fast speed, slow speed, extreme speed, high performance speed, or some other setting level that controls traction, acceleration, speed, and/or control. The set of instructions is instructive to process a set of inputs, which can comprise a first motor speed, a first motor electrical current, a second motor speed, a second motor electrical current, a user setting, or a remote control potentiometer level. The set of instructions is instructive to provide a set of outputs, which can control at least one of a first motor speed, a first motor acceleration, a first motor current, a second motor speed, a second motor acceleration, and a second motor current, for at least one of the motors  158 . In some embodiments, the set of outputs can also control each of the motors  158  independently so that only one motor  158  can be used at a time, if necessary. 
     In block  1002 , the processor determines speed level data, which is based on speed control data obtained from a remote control, as per block  1010 . The remote control can be wireless and/or wired. The remote control can be configured to be handheld in the rider&#39;s R hand during riding. For example, the remote control can be a wearable computer or a mobile phone. 
     In block  1004 , the processor sends the determined speed level data to a first motor speed controller and a second motor speed controller. One of the roller assemblies  136 ,  138  comprises the first motor speed controller and the other one of the roller assemblies  136 ,  138  comprises the second motor speed controller. Accordingly, the first motor controller and the second motor controller respectively sets the first motor  158  and the second motor  158  to a specific speed based on such determined speed level data. Each of the first motor speed controller and the second motor speed controller comprises an electronic circuit which varies at least one of a speed of the motor  158  and a direction of the motor  158 . In some embodiments, at least one of the first motor speed controller and the second motor speed controller is configured for dynamic braking. At least one of the first speed controller and the second speed controller can be a stand-alone unit. 
     In block  1006 , the processor determines an actual speed of the first motor  158  and the second motor  158 , which is based on speed data obtained from the first motor speed controller and the second motor speed controller, as per block  1012  monitoring. Note that the actual speed of each of the first motor  158  and the second motor  158  is monitored from the speed level data from the first motor speed controller and the second motor speed controller since shifting of the rider&#39;s R weight puts different loads on each of the first motor  158  and the second motor  158 , which causes one of the motor  158  to potentially spin faster. 
     In block  1008 , the processor calculates the speeds of each of the motors  158  and then slows the faster one of the motors  158  to match the speed of the slower motor  158  based on such calculation, with this new speed data being sent to each corresponding speed controller, or vice versa, via speeding up the slower one of the motors  158 . The processor then iteratively loops back to analyze the speed control data input from the remote control, as per block  1014 . 
       FIG.  12    shows a perspective view of an example embodiment of an elastically adjustable foot hook according to the present disclosure.  FIG.  13    shows a perspective view of an example embodiment of an elastically-adjustable foot hook engaging a rider&#39;s foot according to the present disclosure. Some elements of these figures are described above. Thus, same reference characters identify identical and/or like components described above and any repetitive detailed description thereof will hereinafter be omitted or simplified in order to avoid complication. 
     The foot hook  112  is secured to the platform  102  via the plate  114  and the fastener  118  extending through opening  116 , which enables lateral rotation of the foot hook  112 . The foot hook  112  comprises of a pair of sections adjustably coupled to each other in a biased manner via at least one elastic member, such as a spring  186 . When the rider&#39;s R foot is underneath the foot hook  112 , the spring  186  is in an expanded state such that the spring  186  applies tension to a lateral side of the rider&#39;s R foot in order to secure the rider&#39;s foot to the board  100 . Likewise, when the rider&#39;s R foot is not underneath the foot hook  112 , the spring  186  is in a contracted state. Note how that the contracted state is shown in  FIG.  12    and the expanded state is shown in  FIG.  13     
       FIG.  14    shows a perspective view of an example embodiment of an fasten-adjustable foot hook according to the present disclosure. Some elements of these figures are described above. Thus, same reference characters identify identical and/or like components described above and any repetitive detailed description thereof will hereinafter be omitted or simplified in order to avoid complication. 
     The pair of sections of the foot hook  112  are adjustably coupled to each other via the fastener  144  extending through one of the openings  146 , as shown in  FIG.  1   . Each of the openings  146  corresponds to a foot hook position for a foot size. Accordingly, the rider R can manually adjust foot hook section positioning based on the rider&#39;s R foot size via selectively fastening or unfastening the fastener  144 . 
       FIG.  15    shows a perspective view of an example embodiment of a pivoting foot hook engaging a rider&#39;s foot according to the present disclosure.

     The board  100  can drivably travel via a ducted fan in addition to, or without, a powered caster wheel, as disclosed herein. For example, the board  100  includes a plurality of ducted fans  210 , one placed on a first end portion, such as a front portion or a leading edge portion, and a second end portion, such as a back portion or a trailing edge portion, of the platform  102 . Note that the fans  210  can be equivalent to or different from each other, in structure or function or shape or size or power output or aerodynamics. Note that the fans  210  can be directionally fixed or rotatable, whether manually or automatically, such as based on direction of travel as automatically determined via an-onboard sensor coupled to the board  100 , such as a compass or a board orientation sensor. The fans  210  can be placed in a variety of numbers and configurations on a top side, lateral sides, a front portion, a back portion, a bottom portion or underside of the platform  102  or even attached to the rider or any other part of the board  100 . One example of the ducted fan  210  can be found in U.S. Pat. No. 4,250,658, which is fully incorporated by reference herein for all purposes. However, note that there are many examples of devices, such as electronic motors, engines, ducted fans, and other propulsion devices, which can be used in or on the board  100 . 
     Accordingly, the board  100  brings a new freedom of movement to skateboarding, approximating many of movements found in snowboarding, while traveling under power across terrain. The board  100  provides an ability to “carve,” as a conventional skateboard can, where leaning the rider&#39;s R weight to one side causes the board  100  to turn in that direction, while permitting a mode of omnidirectional motion, where the board  100  can easily travel forwards, backwards, sideways, and/or any combination thereof, and an ability to transition smoothly and controllably between the carving mode and the omnidirectional mode. The board  100  is configured to allow all of such snowboard movements across terrain where such movements were traditionally impossible, such as flat terrain and up inclined terrain.
