Abstract
Embodiments are directed to an inventory system having one or more drive units that are used, in part, to measure traction of a surface. Traction of the surface may be one of many features that can help with the operation of drive units and may also help avoid collisions between drive units when little room is available between the drive units for navigational errors.
