Claim:
1. A steering system, comprising: a first wheel that is rotatable about a first steering axis perpendicular to an axis of rotation of said first wheel; a second wheel that is rotatable about a second steering axis perpendicular to an axis of rotation of said second wheel; a first modified elliptical gear having its center collinear with said first steering axis; a second modified elliptical gear connected to said first modified elliptical gear, wherein said first and second modified elliptical gears are operable to rotate said first wheel about said first steering axis wherein a ratio of a minimum radius to a maximum radius of at least one of said first and second gears is substantially equal to a ratio of an incremental angle of rotation of said first wheel about said first steering axis to an angle of rotation of said second wheel about said second steering axis that is applied based on the incremental angle of rotation of said first wheel to maintain a predetermined Ackerman geometry; a sprocket operable to turn said second wheel about said second steering axis; and one or more linking members operably coupling rotational movement of said second gear to rotation of said sprocket.
