Abstract
This disclosure describes, in part, systems and techniques for determining compensation models to adjust load cell data and ensure accuracy of the load cells on a mobile apparatus through changing environments and conditions. This disclosure relates, specifically, to generating a compensation model by gathering sensor data for known weights of items over a range of weights, locations, temperatures, and humidity values and building a compensation model to infer compensation error to apply to the estimated weight data from the load cells. The compensation model can be used by a fleet of carts to infer weights of items in a manner accurate enough for sale-by-weight of items.
