SYSTEM AND METHOD FOR GENERATING A PATH FOR A MOBILE DRIVE UNIT
First Claim
1. A method of transporting inventory items, comprising:
- receiving a route request from a mobile drive unit, the route request identifying a destination location within a workspace, wherein the workspace comprises at least one cell associated with a first cell attribute and at least one cell that is not associated with the first cell attribute;
determining a state of the mobile drive unit;
in response to determining that the mobile drive unit is associated with a first state, generating a path to the destination location for the mobile drive unit that traverses cells associated with the first cell attribute;
in response to determining the mobile drive unit is not associated with the first state, generating a path to the destination location for the mobile drive unit that does not traverse cells associated with the first cell attribute; and
transmitting the path to the mobile drive unit.

Abstract
A method of transporting inventory items includes receiving a route request from a mobile drive unit. The route request identifies a destination location within a workspace. The workspace includes at least one cell associated with a first cell attribute and at least one cell that is not associated with the first cell attribute. The method includes determining a state of the mobile drive unit. The method also includes generating a path to the destination location for the mobile drive unit that traverses cells associated with the first cell attribute, in response to determining that the mobile drive unit is associated with a first state. The method includes generating a path to the destination location for the mobile drive unit that does not traverse cells associated with the first cell attribute, in response to determining the mobile drive unit is not associated with the first state. The method further includes transmitting the path to the mobile drive unit.
