Abstract

Embodiments relate to systems in which one or more infrared cameras or sensors are used to measure heat related to the wheels of carts, such as shopping carts. Wheels with bad bearings, that wobble, or that have other issues preventing normal operation tend to generate more heat than wheels that are in good working order, such that an infrared camera or sensor directed at wheel height (e.g., about 2-3 inches off the floor) can detect wheel issues by detecting heat emitted by the wheels.
