  • Patent number: 11591168
    Abstract: A robotic system for arranging packages at a destination according to a stacking sequence. The robotic system uses a storage area for temporarily storing packages that arrive out-of-sequence until they are next-in-sequence for placement at the destination. The robotic system processes an incoming package, determines if it is next-in-sequence for placement at the destination, and if it is, places the package at the destination. On the other hand, if it is not next-in-sequence for placement at the destination, it stores the package in the storage area. A package in the storage area is transferred to the destination when it is next-in-sequence for placement at the destination. By using the temporary storage for storing out of sequence packages, the robotic system eliminates the need for receiving the packages in a stacking sequence, which also eliminates the need for sequencing machines.
