A storage array system including an open undeterministic transport surface, a navigation array disposed in connection with the transport surface, the navigation array includes a distributed feature, a first waypoint at a first position of the distributed feature, a second waypoint displaced from the first waypoint along the distributed feature and offset with respect to the first waypoint in a direction angled to the distributed feature, and a guided bot, arranged to traverse the transport surface, with a non-holonomic steering system, the guided bot having a bot pose determination system employing sensor data detecting the distributed feature, wherein the guided bot includes a controller configured to generate a substantially smooth curved bot traverse path on the transport surface connecting the first and second waypoints with a predetermined optimal trajectory of the guided bot along the traverse path determined based on a bot dynamic model.

Storage and retrieval system

A storage array in an automated storage and retrieval system includes storage spaces arrayed on racks along picking aisles, multiple level decks, where at least one deck communicates with each aisle, where the decks and aisles are configured to define a rolling surface for an autonomous transport vehicle at each level of the decks, racks along at least one aisle at each level are at multiple rack levels that are accessed from a respective rolling surface that is common to the multiple rack levels, and a vertical pitch between rack levels varies for a portion of a respective aisle, the vertical pitch between at least two rack levels of the portion of the respective aisle is related to another vertical pitch between at least two other rack levels of another aisle portion of the respective aisle so the vehicle effects multiple picks in ordered sequence in a common aisle pass.

An automated storage and retrieval system includes an autonomous rover and a multilevel rack structure. The multilevel rack structure includes columns connected by rail beams transversely spanning between the columns. The rail beams define storage and transport levels and provide riding surfaces for the autonomous rover. The rail beams include integral fatigue resistant rover location apertures.
