Abstract

A system for determining material characteristics of a material of a work surface includes a position sensor and a controller. The controller stores a first estimate of the material characteristics and utilizes a planning system to determine an expected profile. The expected profile is based at least in part upon the first estimate of the material characteristics. The controller determines an actual profile of the work surface, compares the expected profile to the actual profile, and determines a second estimate of the material characteristics based at least in part upon the difference between the expected profile and the actual profile.
