1. A system for transporting inventory items, comprising:
- a mobile drive unit;
a plurality of inventory holders; and
a management module operable to;
determine a capability state of the mobile drive unit based at least in part upon a capability message transmitted by the mobile drive unit, the capability message transmitted in response to a determination by the mobile drive unit that a state associated with an ability of the mobile drive unit to complete tasks is changed to a degraded capability state;
select a task for the mobile drive unit to transport an inventory holder from a first location to a second location based on determining that the mobile drive unit is capable of transporting the inventory holder in the degraded capability state; and
transmit information to the mobile drive unit identifying the selected task to transport the inventory holder from the first location to the second location.
