1. A method for traction control for a device having at least one wheel for providing motion on a surface, comprising:
detecting a first wheel slip event of a first wheel having a wheel speed;
responding to the first wheel slip event by stopping the first wheel, gradually increasing the wheel speed of the first wheel;
detecting a second wheel slip event of the first wheel; and
responding to the second wheel slip event by, stopping the first wheel, determining if a steering angle α of the first wheel is less than or equal to a maximum steering angle, adjusting the steering angle α of the first wheel to some first defined angle less than or equal to the maximum steering angle, and
gradually increasing the wheel speed of the first wheel while the steering angle is the first defined angle.
