    Abstract: A system, apparatus, and method is configured to retrieve items and particularly items that are stored in high-density storage solutions. The system can include one or two-piece manipulators with retractable grippers. The manipulators can be relatively low profile and/or low friction to facilitate their placement between a target item and adjacent items on densely packed shelves or trays. In a retracted position, the grippers can be stowed beneath the surface of the manipulators to further facilitate the placement of the manipulators. In a deployed position, the grippers can extend above the surface of the manipulators to increase the contact area, coefficient of friction, and/or surface pressure of the manipulators on the target item. The grippers can enable the manipulators to be thinner than would otherwise be possible to enable retrieval of items from tightly packed storage solutions—e.g., warehouses with higher gross cubic utilization (GCU).

    Abstract: Described herein is an inventory management system and methods of operating a robotic arm assembly in which the level of compliance of the robotic arm assembly is altered in order to achieve a high gross cubic utilization. In at least some embodiments, a robotic arm assembly may adopt a low level of compliance when grasping an item. The inventory management system may identify an appropriate storage location for the item and move the item to that storage location. Upon reaching the storage location, the robotic arm assembly may adopt a higher level of compliance. The robotic arm assembly may then push the item against one or more other items in order to insert the item into the determined storage location.

    Abstract: Tray flipper automation tools are described. In one example, a tray flipper includes a flip arm positioned along a conveyor, a tamper arm, a drive system, and a controller. The controller is configured to detect alignment of a tray on the conveyor with the flip arm, direct the drive system to rotate the tamper arm to a position over the tray, and actuate a tamper plate of the tamper arm to secure contents in the tray. The controller is also configured to rotate the tamper arm and the flip arm, with the tray secured between them, to an inverted position off of the conveyor. Items positioned within the tray can be flipped over when the tamper arm and the flip arm rotate away from the conveyor. The flip arm and tray can then be rotated back, leaving the items resting on the tamper plate for inspection and materials handling steps.
