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.

Abstract: According to the subject matter of the present disclosure, an automated warehouse environment is provided where designated materials handling vehicles are programmed to initiate permission inquiries at primary and secondary nodes of a travel route in the warehouse environment. Alternatively, or additionally, the present disclosure also presents an automated warehouse environment where an asset manager comprises an occupancy grid generator, and a designated materials handling vehicle is programmed to avoid otherwise unpermitted travel along path segments that overlap the locked cells of the occupancy grid.

Abstract: An image of a physical environment is acquired that comprises a plurality of pixels, each pixel including a two-dimensional pixel location in the image plane and a depth value corresponding to a distance between a region of the physical environment and the image plane. For each pixel, the two dimensional pixel location and the depth value is converted into a corresponding three-dimensional point in the physical environment defined by three coordinate components, each of which has a value in physical units of measurement. A set of edge points is determined within the plurality of three-dimensional points based, at least in part, on the z coordinate component of the plurality of points and a distance map is generated comprising a matrix of cells. For each cell of the distance map, a distance value is assigned representing a distance between the cell and the closest edge point to that cell.
