1. A mobile cart comprising:
one or more cameras;
one or more processors; and
one or more computer-readable media storing computer-executable instructions that, when executed, cause the one or more processors to perform acts comprising:
receiving image data generated by the one or more cameras, the image data representing one or more items in a facility;
analyzing the image data using a first classifier to determine first classification data associated with the one or more items;
analyzing the image data using a second classifier that is different than the first classifier to determine second classification data associated with the one or more items;
determining, based at least in part on the first classification data and the second classification data, a first item category represented by the image data and of multiple item categories in the facility;
determining, based at least in part on the first item category represented by the image data, a location of the first item category;
determining a location of the mobile cart in the facility based at least in part on the location of the first item category, wherein the location of the mobile cart is proximate to the location of the first item category; and
performing an action associated with the mobile cart based at least in part on the location of the mobile cart.
