A device in accordance with claim 8, wherein the plurality of leg segments further includes: a) an upper leg pivotally coupled at the axis to a body; b) a lower leg pivotally coupled to the upper leg; and c) a foot pivotally coupled to the lower leg. 10. A device in accordance with claim 8, further comprising: at least one actuator, coupled between at least two leg segments, to move the leg segments with respect to each other in the leg configuration. 11. A device in accordance with claim 8, further comprising: a circular cap, disposable over the leg segments in the wheel configuration. 12. A device in accordance with claim 8, wherein one of the leg segments is coupled to the axis and remaining leg segments extend sequentially around an axis in the wheel configuration. 13. A device in accordance with claim 8, wherein at least one of the leg segments extends transversely to one of the other leg segments in the wheel configuration. 14. A combined and transformable wheel and leg device, comprising: a) an array of leg segments pivotally joined in series, including at least: i) an upper leg pivotally coupled at an axis to a body; and ii) a lower leg pivotally coupled to the upper leg; b) a plurality of semi-circular portions, associated with at least some of the leg segments; c) the leg segments defining at least two configurations, including: i) a leg configuration in which the leg segments are movable with respect to one another; and ii) a wheel configuration in which the leg segments are rigidly affixed with respect to one another, and the semi-circular portions are combined to form a substantial circular outer surface, and being rotatable about an axis in a rotational motion; d) actuators, coupled between adjacent leg segments, to move the leg segments with respect to each other in the walking configuration. 15. A device in accordance with claim 14, wherein the plurality of leg segments further includes a foot pivotally coupled to the lower leg. 16. A device in accordance with claim 14, wherein the plurality of leg segments further includes at least one intermediate leg segment interconnecting the upper and lower legs. 17. A device in accordance with claim 14, further comprising: a circular cap, disposable over the leg segments in the wheel configuration. 18. A device in accordance with claim 14, wherein remaining leg segments extend from the upper leg sequentially around an axis in the wheel configuration. 19.
