Abstract
Systems and methods for a materials handling vehicle to navigate a vehicle transit surface in a warehouse environment including a navigation subsystem configured to cooperate with a traction control unit, a braking system, a steering assembly, and an obstacle detection subsystem to: determine whether the materials handling vehicle is approaching, or has arrived at, a potentially contested intersection; associate with the intersection pre-positioned warehouse object data, a set of road rules, and obstacle data; and navigate the materials handling vehicle through the intersection utilizing warehouse navigation maneuvers in combination with the associated set of road rules, obstacle avoidance maneuvers, or both, the warehouse navigation maneuvers accounting for the associated pre-positioned warehouse object data and the obstacle avoidance maneuvers accounting for the obstacle data derived from the obstacle detection subsystem.
