  • Publication number: 20250313408
    Abstract: A robotic structure having a robotic arm is autonomously operated to pick an item using an end effector of the robotic arm along a predetermined path from a source location to a destination location. A number of identifiers for the item are known in advance. The picked item is moved by the end effector in a manner that improves a likelihood that at least one identifier on the picked item is obtained by one or more sensors. A number of obtained identifiers associated with the picked item is compared to a number of expected identifiers. The robotic structure is autonomously operated to place the item at the destination location based at least in part on the comparison.

  • Publication number: 20240391101
    Abstract: A robotic system to load or unload pallets or other receptacles is disclosed. Image data is received and used to identify an item associated with a topmost receptacle in a stack of one or more stackable receptacles. A robotic arm is controlled to perform a pick and place operation on the item with respect to the topmost receptacle in the stack of one or more stackable receptacles. Successive iterations of identifying, picking, and placing items are performed until a stop condition is determined to have been met, the stop condition including one or more of determining no further items remain to be processed and determining that the stack of one or more stackable receptacles includes a maximum permitted number of stackable receptacles.

  • Publication number: 20240367917
    Abstract: A robotic system configured to detect a target feature and place an item at an orientation determined based at least in part on the location of the target feature on the item is disclosed. In various embodiments, sensor data from a sensor in a workspace is received via a communication interface. The sensor data is used to determine the location of a target feature on an item.

  • Publication number: 20240359927
    Abstract: Data associated with a plurality of items to be stacked on or in a destination location is received. The data associated with the plurality of items enables a first attribute associated with a first item of the plurality of items to be identified. A plan to stack the items on or in the destination location is generated based at least in part on the received data. The plan includes with respect to the first item a plan, determined based at least in part on the first attribute, to place the first item in a stackable container along with one or more other items and to place the stackable container, once filled, in a corresponding location on or in the destination location. The plan is implemented at least in part by controlling a robotic arm to pick up the items and stack them on or in the destination location according to the plan.
