  • Publication number: 20240374391
    Abstract: An acetabular shell insertion tool with an anti-rotation feature is provided. The insertion tool attaches to an acetabular shell including a center hole having an internal threading and an anti-rotation recess disposed around the center hole and having a predetermined shape. The insertion tool includes an outer shaft and an inner shaft disposed within the outer shaft. The outer shaft has an anti-rotation projection shaped to be received in the anti-rotation recess of the acetabular shell so as to prevent rotation of the outer shaft relative to the acetabular shell, thereby preventing the insertion tool from disengaging from the shell. The inner shaft has a threaded tip adapted to be threaded into the internal threading of the center hole to lock the insertion tool to the acetabular shell.

  • Patent number: 10144591
    Abstract: Robotic arms or manipulators can be used to toss inventory items within an inventory system. Tossing strategies for the robotic arms may include information about how a grasped item is to be moved and released by a robotic arm to achieve a trajectory for moving the item to a receiving location. A tossing strategy may also use a trajectory that avoids time and/or space reserved for a trajectory of another tossed item. The receiving location can include surfaces and/or other features that can be manipulated for receiving the item based on one or more characteristics of the tossed item and/or a trajectory of the tossed item.

  • Patent number: 9926138
    Abstract: An item that is moving along a moving surface of an inventory conveyance system may be identified. An orientation of the item with respect to the moving surface may be determined based on sensing information that describes the item and a portion of the moving surface surrounding the item. A removal strategy for operating a robotic arm to remove the item from the moving surface may be determined based at least in part on the item and the orientation. The removal strategy may include a trajectory for the robotic arm to follow as part of removing the item from the moving surface.
