A robotic assistant includes a wheeled base, a storage unit including drawers, a foldable arm connected to a top of the storage unit and including an end of arm tooling (EOAT) connected to a distal end of the foldable arm, an elevation mechanism positioned on the wheeled base and used to move the storage unit up and down, and a control system that receives command instructions. In response to the command instructions, the control system is configured to move the wheeled base, open or close the one or more drawers, actuate movement of the foldable arm and the EOAT to pick up and place external objects from/to a determined location, and control the storage unit to move up/down.

This disclosure includes an item storage and retrieval device comprising one or more stacked circular disks, each disk having a slot on its radius to the center and rotating on a central column such that, when slots on higher disks are aligned, a target disk may be accessed below for item storage or retrieval; which device may further comprise a disk item access unit for placement, orientation, and retrieval; which device may further comprise one or more RFID readers; and which device may further comprise a system and interface for managing and optimizing item storage to and retrieval from stacked circular disks.

An example curtain system can include: a curtain forming a flexible body with an opening at each corner of the body; a tensioning device at each corner of the body of the curtain to couple the curtain to a backside of a rack, wherein each tensioning device includes a hook member with a first end sized to engage an opening in the rack and a threaded second end; and a nut configured to be threaded onto the threaded second end of the hook member to tension the curtain relative to the rack.

Goods storage and retrieval systems and materials handling vehicles are provided. The goods storage and retrieval system includes a multilevel warehouse racking system; a materials handling vehicle comprising a mast assembly, a picking attachment, and vehicle-based cart engagement hardware; a mobile storage cart; and a transporter comprising transporter-based engagement hardware. The transporter-based engagement hardware enables the transporter to engage, transport, and disengage the mobile storage cart. The vehicle-based cart engagement hardware is coupled to the mast assembly to (i) engage and disengage the mobile storage cart and (ii) transport the mobile storage cart to multiple levels of the multilevel warehouse racking system. The mast assembly and the picking attachment are configured to access multiple levels of the multilevel warehouse racking system. The picking attachment is configured to transfer totes between the multilevel warehouse racking system and the mobile storage cart.
