Abstract
An automated guided vehicle (AGV) that is configured to operate with a navigation and guidance system includes a base frame structure that supports a material handling apparatus. Casters may be attached at peripheral portions of the base frame structure to movably support the base frame structure away from a ground surface. Drive wheel assemblies may be disposed between two of the casters and configured to propel and steer the AGV. A suspension system may have intersecting swing arms that are pivotally mounted at the base frame structure and independently attach at each of the drive wheel assemblies. The suspension system biases the drive wheel assemblies against the ground surface to maintain friction of the drive wheel assemblies against the ground surface, such as for traversing sloped or uneven surfaces.
