Claim 0:
1. A system comprising:
a plurality of sensors;
a container positioned on at least one of the plurality of sensors, the container holding a plurality of items, wherein the at least one of the plurality of sensors is configured to determine a first weight of the container;
a robotic arm configured to lift an item out of the container, wherein the at least one of the plurality of sensors is configured to determine a second weight of the container after the robotic arm has lifted the item out of the container; and
an identification server comprising a hardware processor configured to receive output from the plurality of sensors and further configured to:
determine a weight of the item;
determine a visual appearance of the item;
determine, using the visual appearance, a preliminary identity of the item before the robotic arm has lifted the item out of the container, wherein the robotic arm is configured to use the preliminary identity to determine which item of the plurality of items to lift out of the container;
determine a dimension of the item;
determine a barcode of the item;
compare the weight, visual appearance, dimension, and barcode of the item to a manifest for the container, wherein the manifest identifies the plurality of items;
determine, based on comparing the weight, visual appearance, dimension and barcode of the item to the manifest, an identity of the item; and
communicate an instruction to the robotic arm to sort the item based on the determined identity, wherein the determined identity is different than the preliminary identity.
