Tote Based Item Tracking

摘要

This disclosure describes a system for managing inventory as it transitions into a materials handling facility, as it transitions between locations within a materials handling facility and/or as it transitions out of a materials handling facility. In some instances, a user (e.g., picker or picking agent) may retrieve an item from an inventory location and place the item into a tote. The systems described herein detect the item when it is added to or removed from the tote.

主权项

1. A tote configured to identify items contained in the tote, the tote comprising:
a base surface; a plurality of side surfaces coupled to the base surface and positioned to define a cavity; a first antenna coupled to at least one of side surfaces and defining a first plane substantially parallel with the base surface, the first antenna configured to detect an interruption of the first plane as an item passes through the first plane; a second antenna coupled to at least one of side surfaces and defining a second plane substantially parallel with the base surface, the second antenna configured to detect an interruption of the second plane as the item passes through the second plane; a computing system coupled to the tote and in communication with the first antenna and the second antenna, the computing system including:
one or more processors; anda memory coupled to the one or more processors and storing program instructions that when executed by the one or more processors cause the one or more processors to:
receive from the first antenna first information, the first information identifying that the first plane was interrupted;receive from the second receiving component second information, the second information identifying that the second plane was interrupted;determine, based at least in part on the first information and the second information, that the item was added to the tote or removed from the tote; andbased on a determination that the item was added to the tote, add an item identifier to a tote item list.
