1. A method of propelling a wheeled platform comprising steps of:

  • creating an accumulated source of energy upon a first change in orientation of the platform around an axis approximately parallel to a longitudinal axis of the platform and wherein the platform rotates around the axis, and wherein the accumulated source of energy created to rotate the platform around its longitudinal axis is primarily stored and accumulated and not instantaneously transferred into driving at least one wheel of the wheeled platform, and wherein the accumulated source of energy does not directly drive the at least one wheel of the wheeled platform upon the first change in orientation of the platform around the longitudinal axis of the platform;

    storing the accumulated source of energy;

    distributing the accumulated source of energy upon sensing a second change in orientation of the platform around the longitudinal axis by converting the accumulated source of energy into a rotational force to drive at least one wheel of the wheeled platform; and

    controlling a distribution of the accumulated source of energy to propel the wheeled platform in response to the change in orientation of the platform.
