Abstract: This disclosure describes a system for presenting items to a user at a presentation area within a materials handling facility. In some instances, a predicted items list that identifies items that are likely to be picked by a user are determined and, when the user arrives at the materials handling facility, those predicted items are presented to the user for selection. For example, predicted items may be determined and inventory holders that contain the predicted items may be routed to a presentation area and positioned for presentation to the user. The user may browse the presented items and pick the items they desire.

Abstract: The present disclosure describes delivery and/or retrieval of inventory holders to different transfer locations using an automated ground vehicle. In accordance with the described implementations, rather than the vehicle waiting at the transfer location for the agents to arrive and retrieve the items from the inventory holder, the autonomous ground vehicle, working in conjunction with an autonomous transition unit that accompanies the vehicle, transfer the inventory holder containing the items to the transfer location and departs without waiting for the agents to retrieve the items from the inventory holder and continues on to another transfer location at which it will deliver another inventory holder and/or retrieve an inventory holder. Once all the items have been retrieved from an inventory holder delivered to a transfer location, the autonomous ground vehicle may update its route to navigate back to the transfer location and retrieve the inventory holder.
