Abstract:
1. A method for skid steering, comprising: applying a differential torque to each of a first side and a second side of a wheeled vehicle including an articulated suspension system, the first side having a plurality of first wheel assemblies and the second side having a plurality of second wheel assemblies; articulating a subset of the plurality of first wheel assemblies to a height above a ground that is different from a height above the ground of each of the plurality of second wheel assemblies, to vary a cumulative traction of the plurality of first wheel assemblies with respect to a cumulative traction of the plurality of second wheel assemblies, and affect a turning capability of the wheeled vehicle; and modifying the articulation to approach a critical damped response of a vehicle turning rate with respect to a commanded rate.
