The utility model discloses an omnidirectional rolling spherical robot structure which belongs to the field of mechanical technology; the utility model relates to a two-dimension walking control device in a non-electrical control or regulating system relating to land and water transporting tools. The purpose that in the existing spherical robot device at present, a correspondingly stable platform and an installing instrument or installing equipment are arranged in a sphere is mainly solved to proceed with different experiments and tests is realized. The utility model comprises an outer spherical shell, a motor and a rotating disk; besides, the utility model is especially comprises an inner spherical shell, a stable platform and a platform stabilizing mechanism between the outer spherical shell and the inner spherical shell by design, wherein the inner spherical shell and the outer spherical shell are concentrically installed; the stable platform is installed in the inner spherical shell; the platform stabilizing mechanism is composed of a ball bearing and a short shaft. In the process of the omnidirectional rolling of the sphere, the stable platform always keeps the stable motion state of translational motion by the platform stabilizing mechanism. The utility model can be widely used for the aspects of detection, detection, transportation, investigation, entertainment, military, etc.
