Abstract
A method of propelling a wheeled platform, which includes creating a source of energy upon a first change in orientation of the platform relative to an axle housing of the wheeled platform by rotating the platform around an axis approximately parallel to a longitudinal axis of the platform. The source of energy is stored and released to propel the wheeled platform.
Claims16
A method of propelling a wheeled platform comprising the steps of:
- creating a source of energy upon a 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;
- storing the source of energy;
- and
- releasing the source of energy to propel the wheeled platform by converting the source of energy into a rotational force to drive at least one wheel of the wheeled platform.
