Multi-story robotic drive package sortation

Abstract:

Within a sortation center, robotic drives may coordinate to sort packages. In some instances, first robotic drives on a third floor may deposit packages into first chutes that transfer the packages to a second floor. Awaiting second robotic drives on the second floor may receive the packages and may deposit the packages into second chutes that transfer the packages to a first floor. At the first floor, the packages may arrive into a container associated with shipping the packages. Depositing the packages in the first chutes may align the packages with a respective container on the first floor in a first direction and depositing the packages in the second chutes may align the packages with their respective container on the second floor in a second direction.
